We were so close to being done, but hadn’t quite gotten it over the line. Just a few more hours work and we’d have a working pipe lock we could be proud of. And it is something that not a lot of blacksmiths have made.
Our big task of the evening was to get our key finished up and working smoothly to open the lock. Sounds simple enough, but it took a lot of tweaking to get the shoulders in the right place so that it would go into the lock deep enough to open the lock but not too deep as to slip over the spring and be forever stuck inside the pipe.
A bit of grinding on the key, bending of the bow, filing of the key opening as well as the opening at the end of the pipe and it started coming together.
There was also a fair amount of fussing, pondering, and consternation about how things were coming together, but in the end there was a shout and a leap and success!
This really is a piece to be proud of. It’s a very clever, if simple in concept, design that’s a challenge to execute. I’d love to make another one when I had a couple of weeks to kill. Like everything, I’m sure the next one would take less time now that we know what we’re doing, but it’s still a whole lot of steps and and whole lot of fitting to make it work. The time to create a lock like this is going to far exceed what the market would bear, but it’s a fun thing to work on anyway.
And with our apprenticeship under Doug Swenson of Goose Prairie Forge coming to an end, we did celebrate in proper fashion with some Trappist monk ale and a toast.
Sadly, we are coming to the end of our apprenticeship. But first, we have a pipe lock to finish. We left off with encasing the pipe lock in clay and leaving it to dry so that we could “bake” it in the forge and braze the pieces together.
So the clay had a chance to dry out during the week, and perhaps a bit too much. There were some pretty significant cracks that we patched up with some wet clay before we were ready to put it into the forge. Without patching the cracks, the heat would get through there and overheat those sections of the pipe.
We had a bit of a discussion about the type of clay that’s best for this type of thing. Apparently not all clay is made the same. I believe we used stoneware clay (not earthenware clay) with a bit of grit and horse manure mixed in. The horse manure has fibers in it that burn up during the heating process that provide just the right amount of venting to keep the clay from exploding open.
It was interesting to get the clay heated until it was glowing orange and then keep it there for quite a while. The whole process took somewhere around an hour. As it happened our clay did crack a bit and gave us a hot spot on the project, but it didn’t affect it too much. When it was “done” we pulled it out of the fire and rolled it around on the floor using “Viking chopsticks” which were basically pieces of kindling. They were the same tools we’d been using to turn in in the forge too. The rolling about helps get the melted brass to flow around and cover as much of the project as possible.
After several minutes of rolling it about, it was time to drop it in a bucket of water to cool it off. Believe it or not, as the water was still bubbling from the heat I plunged my arm into the water to grab the project and start breaking the clay off of the metal. It sounded insane, but it only got hot a couple of times right after I peeled off a good chunk of clay. Good news! We’d made it that far without it going completely sideways!
With the pipe part of the lock now mostly complete, it came down to details. Time to file off the rough edges and make sure the key was going to fit through the opening. It’s a lot of hand filing and you can imagine that it may have been someone’s job to do nothing by filing all day long. (And another person’s job to keep the files sharpened!)
The other piece that needed attention was the bolt. We had forged the spring onto the center, but we needed to make sure that it was the right length to lock, but also to allow the key to unlock it. That was interesting to figure out as there needed to be a gap between the shoulder of the bolt and the top of the spring, but that was inside the pipe so much of it was just guessing.
At this point in the process it was a bit of a dance between the bolt and spring, the bow that goes over the spring to lock it, and the key that goes over the spring to unlock it. Getting the sizes just right for all the moving parts took a lot of back and forth. There were times we were convinced we were going to get it locked never to get it unlocked again.
But by the end of the 35th session we had a working pipe lock with one exception – there was still a bit of work to be done on the key.
Our 35th session was technically the last of the sessions covered by the North Dakota Traditional and Folk Arts Apprenticeship grant. Looks like we’re headed for a bonus session. But mead was toasted to a successful apprenticeship and good journeys for the journeyman phase of our learning!
After the disappointment at the end of the last session, we worked during the week to get the rings ready to go. They weren’t quite perfect, so we did wind up making a few adjustments (namely grinding the ends down so they connected better). But It didn’t take us long to get those finished up.
So the next step in getting the pipe ready was to cut out the plate that covers the one end (the end with the tail) so that it fit the pipe and had a big enough opening to get the key in. It wasn’t to hard to cut the notch for the key, but we first attempted to hacksaw the thin sheet of metal to bring it closer to the shape we needed for the pipe – and then abandoned that approach pretty quickly. It wound up being a lot easier to just grind it down. So we traced on the sheet around the end of the pipe and just whittled it down on the grinder.
Now the pipe is ready to be brazed. The first step was to cut up some old brass bullet casings into small pieces that we would then lash to the pipe lock. The idea is that we need to hold that brass in place as close to where we need it to flow to seal up the joints between the pipe, plate, and rings. So we used a linen thread (which will burn up during the brazingbrazingBrazing is a metal-joining process in which two or more metal items are joined together by melting and flowing a filler metal into the joint, with the filler metal having a lower melting point than the adjoining metal.

It took a lot of tidbits and a lot of lashing to get enough pieces in place to cover all the spots we needed.
And while all this cutting and lashing was going on, we were also working on the lock piece and fullering another neck on it with the guillotine. While it takes it a bit of effort to make that happen, it’s quite a different type of job than lashing the brass pieces to the pipe.
So the last thing at the end of the day was to pack the pipe to prepare it for the actual brazing process. The first thing that got packed was the center of the pipe with the small bits of brass and charcoal. The brass will line the interior and the charcoal will help support the pipe and keep it from collapsing. Then the exterior needed to be packed in clay. The clay needs to be a certain type, stoneware clay I believe, with a bit of sand (you should be able to feel a bit of grit), and horse manure (which adds some fibers that will allow steam to vent out of the clay rather than crack it). You just pack the pipe, being careful not to disturb the brass lashing that was done, in about 1/4-to-1/2-inch thick clay all the way around, including inside the tail part. (I sure hope I got it packed in that tail part good enough.) The clay should have at least 24 hours to dry, so that’s where we left it for the day.
Next session we’ll get to do the actual brazing process which I understand to be “cooking” the clay for about an hour. We’ll also be working on the lock fitting and getting a spring made for it as well. I suspect that’s all we’ll get done and we’ll have one more session to make the key.
This pipe lock has introduced us to some very different skills than we have done in the past. It’s hard to imagine trying this project on our own without some guidance. The North Dakota Folk and Traditional Arts Apprenticeship grant has really allowed us to push our boundaries for sure!
P.S. We were late for our session today as we were hiring a contractor to build our house. Looking forward to getting our own workshop set up soon!
So the tasks for the day were to get the bands in place and ready for brazingbrazingBrazing is a metal-joining process in which two or more metal items are joined together by melting and flowing a filler metal into the joint, with the filler metal having a lower melting point than the adjoining metal.
Brazing differs from welding in that it does not involve melting the work pieces and from soldering in using higher temperatures for a similar process, while also requiring much more closely fitted parts than when soldering. and to begin work on the locking mechanism.
We started by adjusting the loop and tail on the pipe itself just a bit to make the tail just a bit longer as we’re going to be wrapping two bands over it. That went pretty well.
Then we moved on to making the bands themselves. We need three total: two to go over the loop’s tail and one at the bottom end of the pipe. The two that go over the tail need to have a small “bump” in them to accommodate the tail and that’s where our work began.
We used a fullering swage in a vise and a piece of round stock as the upper fuller to hammer in the bump. Then we put that over the tail on the pipe and started shaping the band to wrap around it.
Once again, sounds easy enough, right? Hammering that square stock to fit around the pipe was much fussier than expected and took a fair bit of time. Then, of course, the challenge was to get two of them to look the same.
Then we needed to somewhat guess where to cut the stock so that the ring would either just meet or fall just short of meeting; this is one place where we didn’t want it to overlap. You can see from that photo that where we initially put the bump in the stock became a pivot point when we started to bend it and it got a bit of a crease in it. As it turned out, that was an important development that would bite us a bit later.
After a bit of fussing, some of which involved hitting the ring simultaneously with two hammers while it was on the pipe, the first ring was looking pretty good.
So we worked on doing the same thing for the second ring and had it nearly complete. We were working on the last finishing touches to shape it around the pipe when that stress point where the bump had creased finally gave up and broke in two. Ugh, but this stuff happens in blacksmithing. We quickly then shaped the much easier third ring, the one without a bump, in the last few minutes of our session.
In the meantime, while all the work on the rings was going on, we were also starting the much harder work of getting the locking insert started. Beginning with something like a 2-inch long, 2-inch diameter piece of round stock the first task was to fuller a neck around it. Once again, simple enough, but this time it’s just plain work. A chunk of steel that size takes a bit of effort to get it moving.
By the end of the day we had one of the bump rings finished, the circle ring ready for cutting, and the lock insert with a decent looking neck fullered into it. The time went quickly!
Next time we should be able to finish up the rings and get the top plate on and perhaps get the brazing done. Then it will be more work on the lock insert and finally the key for it all. I think we’re going to be lucky to finish this before our time under the Folk Arts grant is finished.
After finishing our hinge experiments, we turned to our next interest – locks. We’re starting with a pipe lock, which is pretty ingenious for a simple lock. This is going to be like nothing we have made so far. It’s going to take a bunch of tricky cutting and filing and fitting and brazingbrazingBrazing is a metal-joining process in which two or more metal items are joined together by melting and flowing a filler metal into the joint, with the filler metal having a lower melting point than the adjoining metal.
Brazing differs from welding in that it does not involve melting the work pieces and from soldering in using higher temperatures for a similar process, while also requiring much more closely fitted parts than when soldering. and …
What have we gotten ourselves into?!!!
So this is the example piece we are after. Ours will of course look much different, but it’s good to know where you’re headed.
So we started with a pretty hefty pipe for our pipe locks and cut the end at an angle with a hacksaw (and or angle grinder) and then cut it just a bit more to leave a “beaver tail” piece that we will draw and taper for the loop at the one end. Once that was cut it was into the forge to start drawing it out. It was fun to watch the smoke come out the end of the pipe, but it was also potentially dangerous to quench the pipe as hot steam can also come out of the pipe so you need to be careful how you hold it.
With that tail drawn out to resemble a tang, we turned our attention to the angle cut. There needs to be a small notch in it to hold the plate that seals the end and that’s a bit tricky to cut. It also has to be just right in both the depth to match the thickness of the plate and the angle to not be too sloped or too abrupt. We fussed over that for quite some time with files and rotary sanders and whatever it took to get it the to something near 45-degrees and flat and smooth.
It was a bit tough to work around the tail we had drawn out and we bent it out of the way for a bit of the process.
The next step was to cut the hole in the other end of the lock so that the clasp can be inserted into the pipe. The cuts perpendicular to the length of the pipe were easy enough, but the lengthwise cuts eluded us. Doug showed us how to do an X-cut to get that opening, well, open. We were confused about how the X would actually work as we were imagining the X on the top of the pipe where it would connect the two parallel cuts we made. And while that was technically what was needed it didn’t create the X looking at the top of the cuts, but rather from the side, which allowed the unwanted metal there to be “scraped” away. We would have never come up with that.
The last bit before ending this session was to bend the tail we had drawn out and get that ready for fastening later. We talked a bit about cutting the plate to cover the end and made a couple of initial cuts, but the time had flow by once again and it was time to lay it aside until the next session.
… with one set of arms and the tip mostly completed. So that left the second set of arms and the hinge part left to do.
I think it’s a testament to how far our skills have come that I don’t have much to write today. We simply cut the second set of arms and then rolled the hinge. We did experiment with those cuts just a bit. We started one from the bottom and cut up and the other from the top and cut down. We think the one cut from the top down worked just a bit better and reduced the amount of dressing required later.
The rolled gudgeongudgeonA gudgeon is a socket-like, cylindrical (female component) fitting attached to one component to enable a pivoting or hinging connection to a second component, the pintle. got a little tight for awhile and we monkeyed with it for a bit to get it straight, evenly thick, big enough for the pintlepintleA pintle is a pin or bolt (male component), usually inserted into a gudgeon, which is used as part of a pivot or hinge., and with enough of a scarf for weldingweldingWelding is a process that joins metal by using high heat to melt the parts together and allowing them to cool, causing fusion.
Welding is distinct from lower temperature metal-joining techniques such as brazing and soldering, which do not melt the base metal.. Once that was done the weld went pretty well. The last part we cheated on just a bit due to time. We drilled the holes rather than punching them through.
We’re reasonably happy with how this turned out. As with everything, after we make about 50 more of them we’ll probably be pretty decent with them. But for this attempt it’s not too bad.
So after taking a break for the holidays, we jumped back in to making hinges. We had decided to scrap our first attempt and start over. So being blacksmiths, the first thing we needed to do was to make some tools.
The first time we had used a double-sided chisel to make our cuts and that was something we wanted to change. So we made a couple of single-sided chisels, one wider than the other, so that we could make cleaner cuts.
Using a piece of round stock that was probably 108510851085 steel is a hardenable steel steel, we forged the one-sided taper and then ground the edge. We still need to get better at grinding, but they were ready for use. We opted to not go through the thermocycle-quench-temper routine as it was very likely that any temper would be lost as we worked. And the 1085 steel is a much stronger steel than the 1020 that we were using for the hinge, so the hardening probably isn’t necessary.
Once the chisels were made, it was on to start the hinge. We brainstormed what we wanted to do differently this time and one change was that we were going to start at the tip end rather than the hinge end. And we wanted to try straight, but angled cuts rather than a straight, then angled cut.
So we marked our “armpit” with a punch and set about cutting it with the new chisels keeping the flat side toward the center. These were much cleaner cuts than our first attempt and we were quite happy with them. The tapers basically made themselves!
Next up was bending and/or curling the arms we had just cut. We used the hot cutting hardy tool to widen the split of the arms from the center portion. Once they were bent away we used scrolling pliers to put the curves in them. We also pulled out the mandrel cone to get the curves just right. We chose to not completely perfect that at this point as it is likely they will get bent as we continue working on the piece. We can finish that up when we are further along.
Once the arms were cut and bent out of the way, we turned our focus to making the spade tip. This too was in a much better starting spot than our first attempt and all we needed to do was to taper it to a point and then pull the width out a bit wider.
The taper was easy enough and we mostly avoided making a fish mouth at the tip. But pulling the width out was a bit more challenging. We talked about using a rounding hammer, or the cross peen side of our regular hammers, but we wound up going with a ball peen hammer and that worked out pretty well. It did reduce the thickness of the tip in the middle and left it thicker towards the tip, but we may or may not be concerned about that.
After about four hours of work, we had a reasonable semblance of what we are going for and are ready to come back and cut the second set of arms before turning to the actual hinge.
Since it had been a couple of weeks since our last session, we decided to take a step back a revisit some of the basics. We had decided to scrap our attempt at and “armed” spade hinge and start over. There were several flaws to overcome and lessons learned in what we had done so far. We all agreed that it was best to begin anew with a different plan and some different tools.
So instead of getting started on a new version of the hinge, we took a detour and decided to make Thor’s hammer pendants. Thor’s hammers are just a classic Viking-age trinket that should be a nearly subconscious project to make. However, while Rob had made one or two, I had never attempted one to this point. I had been looking forward to doing so, however!
We started with some sizable round stock – maybe 3/8-inch or so – and then proceeded to shoulder it on two dimensions (sides) to make what amounted to a square tang that was even with the edge of the stock and not centered in the middle. That seemed weird, but the next step was to cut it off and then flatten what remained of the round stock and so having an edge to use for the “bottom” while pounding the thickness flat made sense. When we finished that step, we had what looked like oars or a broom ball stick.
We then used a nail header, like the one we had made earlier, to create the shoulders of the hammer. The nail header worked brilliantly and much better than any fuller or guillotine we had tried in the past.
Then it was a matter of hammer control to get the angles of the Thor’s hammer in place. That was a little tricky as the hammer can hit the anvil when you’re at an angle like that.
The last step was to bend the tang over and twist it around to form the loop. It’s really quite easy to do, except it cools off so fast. It took more heats than you’d hope to get that finished. (And we cheated and used a torch to finish it up.)
It’s interesting that they have different shapes, but both are classic, traditional Thor’s hammers. We both want to crank out scores more of these as they are fun to do – and great practice for hammer skills!
So with the completion of our “simple” spade hinge, we wanted to move the degree of difficulty up a notch. This time we wanted to make it a little more ornate and add a few additional skills. We used this as our model. We knew ours would look different, but we were going for the multiple “arms” and also adding a negative hinge.
So once again we began with a 1-inch by 1/4-inch piece of bar stock. We had a discussion around where we should begin and decided that making the gudgeongudgeonA gudgeon is a socket-like, cylindrical (female component) fitting attached to one component to enable a pivoting or hinging connection to a second component, the pintle. should come last and that we would start with the arm closest to it. We began hot cutting the “slivers” that we would bend away to become the arms. A few tricks that we used were to mark some measurements (6″ and 8″) with soapstone on the anvil and also to use a center punch to mark where the cuts should begin and end on each side. It can be hard to see marks once the metal is hot, but the center punch divots seem the best way to go about that. It took a few heats and worked best if two people helped with the cutting – one to hold the stock and set the cutter and the other to swing the hammer. Once we had cut all the way through on both sides, we used the vise to hammer the arms to a 90º angle.
We then moved on to cutting the second set of arms following the same center punch trick and these cuts were much less ragged. (The first time we do most anything we learn enough to do better the second time.)
Now came the tricky part. Smoothing out the stock between the first set of arms and the second. We started by removing the shoulder that was created by the cut. The difficulty here was finding a place to work on the anvil where the arms didn’t interfere. The back corner seemed to work best. So after we smoothed the shoulder out a bit it was a matter of smoothing out that center section and tapering it from one set of arms to the next and getting the size to be (mostly) consistent the entire length.
We finished the day with the center section in a good place, even if not entirely finished. We wanted to give ourselves room to work with the arms so we left a bit of work yet to be done.
Next session we’ll be focusing on getting the arms tapered and curled and adding the spade to the end. After that it will be to fold and weld the end to create the gudgeon before moving on to the creation of the negative hinge. We chose this project because it would challenge our skills and it proved to do just that. We’ve already decided that the next one we do we will cut the first set of arms and then work the taper before cutting the second set of arms. Every project is a learning experience! And we also recognized that if you were to make several hinges, you would have patterns and jigs and some specialized tools created to make the process easier and more consistent. (And we also believe our example hinge was created in sections and welded together.) Maybe someday ….
So with the strap part of the spade hinge finished it was time to move on to the pintlepintleA pintle is a pin or bolt (male component), usually inserted into a gudgeon, which is used as part of a pivot or hinge.. We were starting with the basic spike / bolt design for our first hinge. Our first session consisted almost entirely of taking a 1-inch by 1/4-inch piece of 1020 bar stock and creating the pin that the loop of the strap hinge would fit over. (I believe that loop part is called a gudgeongudgeonA gudgeon is a socket-like, cylindrical (female component) fitting attached to one component to enable a pivoting or hinging connection to a second component, the pintle..) Once again, it sounds simple enough, but creating shoulders on the bar stock and then drawing out the pin and rounding it to size took a few hours. We weren’t able to finish that in one session as Rob was on call and we had to cut it short after 2-1/2 hours.
So when we returned the following week it didn’t take too long for us both to get the pintle sized to the gudgeon. Then we moved on to creating the spike that would be driven into a timber to hold the hinge. The first step was once again to create a shoulder that would define where our tapered spike would begin. Once that shoulder was set it was just a matter of a lot of hammer blows to get the spike drawn out and tapered. There’s always a certain amount of fussing about keeping things square and straight, and we had to revisit our shoulder a few times to keep that crisp.
Once the spike was the length and shape we wanted, the last step was to bend it 90º so that it could be hammered into the wood. It required a yellow-hot heat and we had to make sure we weren’t burning the tips of either our pin or spike. But once it was hot we put the spike part in a vise and hammered the pin and the square below it until it got to the correct angle. After that it was just a matter of dressing any remaining bits up and then we were done!
They turned out really well and seem quite functional. We might try to use them on a garden gate in the future. We specifically kept this project simple and a bit old school because the next one is going to kick the hinge design up a notch.
So today we started on what we’re calling a spade hinge. Something “simple” like the ones shown in this photo, though ours will be a bit shorter.
While the spade part of the hinge is something I think we could handle, the business end of the hinge where a pin of some sort is used is something new to us.
So as expected we started with a piece of bar stock and chose one about three feet long where we would each work one end of it and then cut it in half. We started with the business end, so our first task was to fold over the end about two or so inches, while maintaining a space for the pin, and then forge weldingweldingWelding is a process that joins metal by using high heat to melt the parts together and allowing them to cool, causing fusion.
Welding is distinct from lower temperature metal-joining techniques such as brazing and soldering, which do not melt the base metal. it back onto the bar stock. Sounds simple enough but keeping the tube for the pin makes it a bit more challenging. We used the swage block and a piece of round stock for the pin to make sure the fold to create the tube was round and allowed the pin free movement. Then it was a matter of forge welding the stock – keeping that round tube for the pin intact. You have to get the crease where it transitions from round to flat tight without smushing the tube.
We each managed to get our ends rounded up and welded and they came out pretty even with each other’s. Next time we’ll be working on the decorative spade end, but we’ll also have to work on the other half of the hinge that attaches to the door frame and get it to match the tubes we made. I’ve no idea how that is going to happen. Stay tuned!
Today we started on our first door/cabinet hardware project which will be the focus of our work this year. We made a simple strap hinge similar to those on the Måstermyr chest. I had attempted to make one of these before but had not finished, so this was going to be the first actual hinge we had made.
The first step was to take a piece of bar stock and hammer it to thin it out a bit. We were trying to match the dimensions of the Måstermyr hinge as best we could and came pretty close. Then the next step was to draw out a “tang” for the loop that would connect the two pieces of the hinge. This involved tapering one end, setting shoulders, and then rounding the taper. On the other end of the bar stock, we used a chisel to punch a hole through and then drifted it into a circle.
After that the two ends needed to be cut to length and hammered a bit more to make the dimensions we were going for.
Next was to make the holes for the nails to go through when you attach the straps to the chest, or whatever you might be using them on. The holes actually went farther back on the strap than I initially expected, but it made sense in order to give the strap clearance around the wood joint so that it could move freely. While traditionally we would have used a punch to set the holes in the straps, we opted to use a drill press – partly for time’s sake and partly for the experience of drilling through metal. We’ve punched holes through metal several times, but never drilled a hole before. It turned out well and was very quick (and fun to do), but it felt like cheating. Not going to be our preferred way to do that going forward.
We also invented a word today – “schmoogle”. A schmoogle is those fold marks that appear when you are working the edge of a piece of metal. Apparently they can happen because the hammer you are using is too light and is only moving the surface of the metal and not getting all the way through. It happens to me a lot. Like every time I make something. It’s why we swung the big sledge hammer making our nail header, and after that experience I’m determined to start using bigger hammers when called for. I guess my arm will just have to get used to it.
“Schmoogle” is a great word for this. “I schmoogled this piece.” (Adverb) “The drift hole is starting to schmoogle.” (Verb) “My schmoogle isn’t too bad.” (Noun) Perhaps there is an official word for this phenomenon, but until we learn what it is, we are going to use this term.
The last step in making the hinges was to connect the two pieces. We started with a small curl at the very end of the tang end and then heated up the tang and slipped it through the hole of the other piece and curled it into a loop. Ideally, you’d like to do that in one heat. Then we curved the one piece that would have gone on the lid of the chest to match the curve of the wood. We used a leaf spring as a guide for the curve. And there we had it! I finished – and matching – set of strap hinges.
Something that once again I underestimated the effort to accomplish. I figured we’d be done in under three hours, but it took us nearly five. And we’ve gotten much quicker with our work, especially on a project such as this that didn’t really introduce a lot of new techniques. Really makes you appreciate the work that went into simple, every day items.
We continued work on our nail header today. Last time we had drawn out the taper on one end for the handle. It was heavy work, even on the soft steel we had chosen. It was looking pretty good, but we all agreed that it was a bit too short. So we decided to add another inch or two to it – and we also decided to speed things up and use the trip hammer. Rob and I had never used the trip hammer before and it gave us an opportunity to experience that. It’s easy to see why folks like those as it turned several hours of hard hammering into about 5 minutes of mesmerizing pounding. Doug helped us set the shoulders for the handle. It might have been a bit of “cheating”, but we got introduced to a new skill and got our handle where we wanted it in short order, which left us the rest of the day to work on forming the business end.
We took another short cut and used the chop saw to trim the stock down. We could have hot cut it using a hardy tool, but once again we wanted to use our time working on the more important aspects of the tool.
So the next step was to thicken business end by hitting the edges. Since this piece is a large mass of steel, using our usual hammers (800-1200g) would only really slide a portion of the edges rather than compressing the entire piece. So we got out the 14-pound sledge hammer to see the difference that would make in how the material moved. Boy did it make a difference! Besides moving it much more quickly, it moved it better – meaning no sliding toward the end and creating a fish mouth, no creating lips on the edge that then have to be hammered back in place (and really accomplish nothing). It was a beast to swing, but it sure felt good when it connected with the hot steel.
After we got the bar to the size we wanted, the last step was to punch a hole through. The Måstermyr nail header had five holes in it, but we opted to start with one and then decided later what other sizes/types of holes we would want to add. The idea would be to have the bigger holes closer to the handle, so we could have some pretty good sized ones before we’re done.
Since this was such a large, hot piece of metal we’d be punching through, we chose to use an essentially throw-away piece of round stock and taper the ends. It wouldn’t pay to harden it since it would lose that as it went through the hot bar. So we found something in a size that would make a decent nail, tapered the end, and started punching. It was surprising, actually, how easily and quickly that hole punched through. But we did have to cool the punch after every hit (sometimes in water and sometimes in a beeswax/olive oil mixture) and straighten it out a couple of times. When we finally got it through we just kept driving to push it all the way through. That didn’t go so well. We had failed to taper the top end of the punch which would give it some relief and allow it to drop out. So we basically had our punch stuck in the nail header and with the kind of heat involved there was a risk of it weldingweldingWelding is a process that joins metal by using high heat to melt the parts together and allowing them to cool, causing fusion.
Welding is distinct from lower temperature metal-joining techniques such as brazing and soldering, which do not melt the base metal. or simply permanently getting stuck in there.
The fix for this situation was brilliant and shows why we are apprentices and Doug is a master. He opted to cut the top of the punch to about an inch above the bar and then grind a taper on it. We then heated it up to orange-red and the cooled one side of the punch in water to harden it. Then we hammered on that end and lo and behold it went all the way through and fell to the ground. Disaster averted!
We had done it! We had forged our nail header and punched a hole in it. It was ready to be used and we just had to give it a try. We found another piece of round stock, set the shoulder, hammered it square, and then cut it off about twice as high above the shoulders as the diameter of the nail. There’s a trick to cutting it off with only cutting on two sides, but we’ll have to practice a bunch before we’re ready for that. For now, the goal is to cut equally from each side of the square nail but not quite fully through. Then you heat it up, place it in the nail header, twist the excess stock off, and hammer the nail head. The goal is to have a nice, even, , flat, centered nail head. It didn’t quite come out that way at first, but a second heat allowed us to improve it quite a bit.
This was a massive undertaking for a small, everyday tool. If a person (or actually a team of people) had to make these, you can bet they’d take care of them. They are not easily or quickly replaced.
Apprenticeship session 21 marked the beginning of our work on the FY21 grant projects. We are focusing on door and cabinet hardware this year including hinges, locks, latches, and handles. So to begin with, as all good blacksmiths do, we didn’t begin by working on our projects, we began by making a tool.
Since nails are required to fasten hinges, latches, and other hardware, we wanted to make a nail header to be used for making nails. The Måstermyr find included one that we want to emulate. It had five holes, most of which were for nails and but one was for rivets (tapered vs. straight holes). Ours may not have that many holes, but we do want to be able to make both nails and rivets.
So we started with a BIG piece of 1020 bar stock (this won’t be hardened). The measurements from the Måstermyr find were actually larger than I expected. It was 22.9 x 1.9-3.8 x 2.1 cm. (approx. 9 x .75-1.5 x .83 in.). So we were in for swinging big hammers today.
We spent the entire day working on tapering out the handle. We often were working as a 3-person team with one holding the bar, one being the blacksmith, and one being the striker. That’s a lot of fun actually. You have to watch yourself from getting wrapped up in it and not paying attention to what is happening with the piece.
One trick we did because the bar was so long and heavy was to place a brick on it when it was in the fire to keep it in place. Without that, we’d either have to had to hold it the entire time or else it would flip out and send hot coal and metal flying.
Before we arrived, I actually thought we might get the nail header finished today and even have a chance to make nails. Nope. It will be another full session, at least, to finish shaping the handle (including upsetting the end), cutting the piece, and punching the holes through.
While technically we are done with the FY20 grant, we had a couple of projects that we hadn’t yet completed and we wanted to get them done before moving on to the FY21 projects. These final projects being a hammer and an axe. We wound up doing three sessions in one week (Thursday, Saturday, Tuesday) to get these wrapped up.
Last time, we had finished shaping and thermocyclingthermocyclingThermocycling is the process of heating steel to critical temp (non-magnetic) and then letting it air cool. Usually done three times in a row. our hammer head and all that remained was to heat treat it, quench it, temper it, dress it, and add a handle. There wasn’t a lot of forging on the hammer today; mostly just finish work. We did get to heat it up and try something a bit different with the quench. The was to drip water over the face of the hammer which is where it needs hardening the most but leave the middle portion a bit softer to absorb the forces when hammering.
The rest was finish work with a bit of tempering and then putting the handle on.
The axe head had been left with the hole punched through and drifted just a bit. We still needed to draw the langetslangetLangets are the "ears" associated with a drift hole, such as on a hammer or axe, where to flatten the sides you pull the mass up into ears instead of pushing it to the sides which would distort the hole., taper the face, and draw the beard out, not to mention heat treat it and put an edge on it.
So we began by drawing out the langets again, which turned out to be similar to the hammer head, but slightly different since we were going to fullering the one side to set the beard. So after the sides of the eye were mostly flat, we started drawing the taper of the face. Not too far into that, however, we used a round fullering tool to shoulder the area for the beard and mark where the tapering needed to be done in earnest.
Once we got it to a size we liked, we forged and then ground the edge, but not too sharp. Because the next step is the heat treating. With the axe, we opted to quench in oil and then water.
Once again, the last steps were finishing the edge and tempering. We finished we a good, solid, sharp, usable axe head. Now we just need to find the right handle for it.
The North Dakota Council on the Arts has a Folk and Traditional Arts Apprenticeship Program that “is designed to honor and encourage the preservation of North Dakota’s diverse living traditions by providing grants that allow master traditional artists to pass their skills and knowledge to apprentices on a one-to-one basis over an extended period of time.” We were encouraged to apply for this program to help us continue to study under the master blacksmith Doug Swenson of Goose Prairie Forge and were lucky enough to be funded from July 2020-April 2021.
Last year our projects represented a wide sample of items and techniques. This year we are going to get more focused on hardware for doors, cabinets, and chests. This type of work requires greater precision and is going to push our skills.
The schedule is based on 15 flexible sessions of 3-6 hours in length taking place 2-4 times per month for a total of 50+ hours. The apprenticeship will begin July 1, 2020 and conclude by April 30, 2021.
These projects are going to be very challenging, but once again the challenge will be squeezing it into everyone’s busy scheduled. And the impact that COVID-19 has on our program is yet to be determined.

Wow. What a year. Honored and encouraged, for sure.
We kind of summed up the amount of growth that has taken place by another well-known quote: “Do not seek to do what the master has done, instead seek what they sought.”
When we first started on our projects this year, we were looking for direction for every step along the way in the projects. At the end of our grant period, we talk for a bit then agree on what we are working on and how to approach it and then we just dig in and ask questions when we are unsure of the next step or how to correct something. We can work independently for the most part, but we still have a lot to learn.
We had a nice selection of projects which provided a wide variety of skills and techniques to work on, and while challenging, were somewhat basic/fundamental. Or at least they seem so now, here at the end. But getting a solid foundation in the fundamentals is going to pay dividends as we continue on. You have to crawl before you can walk – we’ve taken our first steps!
The last of our official sessions under the FY20 NDCA Folk and Traditional Arts grant had us working on our hammer and starting an axe. Yay! We’re finally getting to the axe, which is a project I’ve been looking forward to for a long time.
Last week we started our hammer head and had managed to get the eye punched and drifted and the cross peen started. We still had a bit more drawing and shaping to do on the peen end today, and of course there’s still the heat treating, hardening, and dressing to do as well.
So we dug right in and started pounding on that cross-peen end. This is a solid block of tough steel and it doesn’t want to move too quickly. But after a while it started to shape up and we then turned our focus to the langetslangetLangets are the "ears" associated with a drift hole, such as on a hammer or axe, where to flatten the sides you pull the mass up into ears instead of pushing it to the sides which would distort the hole..
Langets are formed when you take the mass of metal that was pushed out when you drifted the hole for the handle and pull it upwards. Why would you do that? Because you want the side of your hammer to be flat and not have that bulge in the middle. Why is that important? It keeps the hammer from sliding off the anvil when you set it down and you can scrape the hammer scale off the anvil with the flat side. So if form follows function, you want a flat side to your hammer.
It sounds easy enough, once you understand what you are trying to do and why, but once again it’s harder to do than it sounds. The trick is to not change the shape of the hole you’ve created too much. So much of the time you are pounding on the sides of the hammer, you have the drift punch in the hole rather than using tongs. That helps keep the shape a bit and gives you better control too.
And as much as moving this rather large chunk of hard steel takes a bit of oomph, it’s surprising how it also requires finesse to get it just right. Keeping the bottom flat, the sides flat, the slopes of the langets straight, and the hole straight and true means a lot of little taps on top of the big hits from earlier in the process.
We finished the day with the shape of the hammer head where we wanted it and began the heat treating by thermocyclingthermocyclingThermocycling is the process of heating steel to critical temp (non-magnetic) and then letting it air cool. Usually done three times in a row. it three times. The final heat/quench and tempering will have to wait until next time.
We started with a chunk of 4140 bar stock to begin making our axe. It begins a lot like the hammer in that you need to drift a hole in the middle. It’s a bit tricker though as the stock is rectangular instead of square and you’re trying to cut through the narrow end. So we started with the same trick of putting the stock low in the vise and scoring it to mark the middle. This hole is further to one side since, unlike the hammer, there’s really only one business end of an axe.
Doug had spotted a jig for making axes in one of the Norwegian/Swedish blacksmithing books and had replicated it. We were a little worried that the heated block would get stuck in the jig or it wouldn’t fit in it in the first place, but it worked brilliantly and was much more sturdy than having another person hold the block with tongs. It seems nearly impossible for a solo smith to do both hammer and tongs work on this and get that hole drifted at all, much less straight. The jig makes it easier and better no matter how many folks are available for the work.
After nearly 6 hours at the forge today (time always seems to fly at the forge) we called it a day when our arms gave out. We still have next weekend to do the final touches on the hammer and get the axe into shape as well.
While this marks the “official” end of our grant work for FY20, we learned this week that we have been approved to continue our apprenticeship for FY21. Exciting! We won’t be starting on that work until July, so look for a separate post with information on our plan for the new grant and the projects we’ll be working on.
This one was a doozie as it was double, maybe triple, long. Today we focused on getting one hammer made. Sounds easy enough, right? One hammer, one long day, two (or three) people, no problem. Uh, we got a long ways but we did not get it done in the 5+ hours that we spent on it.
Because a good start to this project is everything, we started by scoring our block of 1045 square steel (maybe 1-1/4 inches) with some lines to make sure that we got our hole for the hammer centered and straight on the block. While you can make some adjustments as you go, it’s better to take your time at this stage. It’s hard to recover from a badly placed hole. So we marked some lines on the top and bottom to find the center down the longest dimension (length) and copied those to the opposite side. We then wanted to mark our “center” in the narrow dimension (width), but this mark needed to be off-center just a bit to allow for the lengthening of the one side as we draw out the cross peen. It was about a 60/40 split. We used a straight edge and a drill bit to make the score marks.
After we scored all the lines we needed, we got out a chisel and marked the spot where we wanted the drift to be. It was a fairly significant pilot cut as we were going to need to be able to see it when the block was heated to yellow hot. We made the same marks on both the top and the bottom of the hammer head.
Next was to get the block good and hot and begin to punch a hole through the block. As you can imagine, it took a lot of heat and a lot of times in and out of the forge to get the chisel to go all the way through. We punched from both sides and met in the middle. It was a two-person job as one person worked the tongs to pull the block out place in on the anvil, hold it in place, and then flip it over while the other person carefully placed the chisel and hammered the bejeezus out of it. It is a best practice to switch sides of the anvil (and therefore the block of steel) to compensate for any thing that might not be quite plumb or level. It became a bit of a dance as it was two or three strikes with the hammer, dunk the chisel in water to cool it off, switch sides of the anvil and repeat.
We finally managed to get the chisel through the entire piece and it was relatively straight. Next step is to make that hole big enough to hold a handle, so we used increasingly larger chisels/drift tools until we had a good, straight eye formed. It was easy to check if it was straight by lifting the hammer head up on the drift tool to eyeball how it was sitting. We did need to make some minor adjustments along the way.
Once it was large enough and straight enough it was time to start drawing out the peen end. That’s a pretty solid chunk of tough steel to try to get moving, but if you heated it up enough it started to move. This was where having a team of people was really handy as we had a fireman/tongs person, a lead blacksmith doing some hammering, and a striker delivering some powerful blows to get it into shape.
Due to some other commitments, we weren’t quite able to finish the hammer head in one day. We still need to finish the peen and draw out the langetslangetLangets are the "ears" associated with a drift hole, such as on a hammer or axe, where to flatten the sides you pull the mass up into ears instead of pushing it to the sides which would distort the hole. around the eye, plus there will be some work to finish the face of the hammer as well. We’ll get it done at our next session.
A couple of other things we learned today. One reason that it is preferred to drift the eye hole rather than to drill it into the block of steel is that steel has grain and fiber, somewhat like wood. Rather than break those fibers by drilling a hole it is better to split the fibers by drifting to maintain their strength.
The end of our grant is fast approaching and we’ve got a few projects left to finish up. So today is going to be another double session of basically finishing the projects we were working on last week.
With the beeswax/tar goop that we painted on the canvas last week now dry, it was time for final assembly.
We affixed a couple of crossbeams under the bellows. They serve two purposes: 1) to allow air to flow into the valves from underneath and 2) to set the angle of the bellows for best airflow effect.
The best angle for the two bellows is to have the airstreams cross about three inches in front of the snouts with the soapstone barrier about an inch in front of that. We lined up some steel rods down the centerline of each bellows to determine where the airstreams would cross and then marked the crossbeams before affixing them. There’s no special measurements of where they should go other than the back one shouldn’t obstruct the valve holes and the front one should stick out the sides so that it can be clamped or bolted or staked into place when using to keep them from moving about.
The last step today was to attach the handles and test the results.
There is one final step left to do on the hinges which is to affix the leather hinges to the sides of the side, but we want to use them for a while and break in the leather before making a slice and tacking them down. And we also need to drill the hole in the soapstone and maybe build a portable table to hold it all for using at events or just outside on nice days.
Now back to the shears…
Shears are one of those projects that seem like it should be easy, but in practice turn out to be more difficult than imagined. We had started with about 18-inches of 9/16-inch 108510851085 steel is a hardenable steel round steel stock. First we flattened out the spring area in the middle and drew out the ends to thin them out. And that’s where we left them last week.
So this week we needed to create the blades on each end and fold it and then finish it.
It’s been a while since we’ve done blades so it was a nice refresher. Drawing them out, grinding them, heat treating, and tempering are things we are familiar with but with shears the blades need to be at 90º angles to the flat spring area and facing the same direction as each other. I can neither confirm nor deny that there were mistakes made in that process. It’s really hard to get two blades that are exact mirrors of each other.
The last step was to fold them and line up the blades. Keeping them equal lengths so that the tips were even required wrapping the spring area around a big steel rod (vertical worked best) and either push/pulling the ends or hammering a bit on the spring area.
Then the big test of whether or not they would actually cut anything.
Well, they did pass the test, but we learned so many things that we’d like to do differently that we may have to try another pair soon. Things we’d do different are: 1) longer blades and not so much concern about the length of the reins, 2) have the blades be flat on two dimensions (spine and one side) that that they don’t rub and interfere with use, and 3) set shoulders to define the spring and blades areas, and 4) draw out only the reins area and not the blades area (we needed a bit more mass to work with).
Good thing we brought donuts to the smithy today because we spent over 6 hours in the forge getting these two project finished up.
We had two tasks for today’s session: 1) work on the bellows and 2) start forging a shears.
The Viking-age Bellows
We did get our homework done and got the copper snouts attached and the canvas tacked on. Both were fairly simple jobs and we were happy with how easily the canvas laid in place. Working around curves and hinges we were a bit worried that it would get fussy, but it was pretty straightforward and fun!
So the next step in the bellows process is to seal the canvas. It’s not really intended as much to make the bellows air-tight as it is to protect the canvas from the heat, sparks, and hard use.
For a sealer, we used a mixture of beeswax and tar (pitch) and heated it over a campfire. It’s highly flammable, not to mention messy. We melted the beeswax first then added the tar pitch until it became saturated – the mixture will only take so much. Once that was done, it was time to brush it on the canvas.
Painting the mix on the canvas was easy enough, if a bit sloppy. The color of the mix as it dried … well, none of our suggestions about what we would name it should be repeated here. 😀
After that we set them aside to dry and started working on our shears.
Since a shears is basically two blades on one piece of stock we weren’t sure the best way to go about that. We had considered creating the blade on one end and then putting in the flat spring portion before making the blade on the other end – basically working from one end to the other. However, Doug recommended that we actually start in the middle and flatten the spring section first, then draw out the reins, and lastly add the blades to the end. Seemed like an odd way to go about it until we got into it and then it made perfect sense. It’s easy to make one blade, it’s hard to make two that match. His suggestion would give us the greatest chance of having that happen.
We managed to (mostly) get the spring section flattened out of the 3/8″ round stock and began drawing out the reins before calling it a day. By the end, we knew we’d been working with 108510851085 steel is a hardenable steel steel rather than 1020 all day. We’ll pick this up where we left off next week – and get the handles and mount on the bellows too!
Since we’ve lost so much time this spring, today was an extra long session and we actually got to work on two projects: cooking utensils and our bellows.
I had seen these utensils – I dunno what we should call them, maybe bread bakers? – at a couple of reenactment events we had attended. They looked interesting and reminded me of the “Tonka Toasters” we use over campfires to make pies and sandwiches.
While the coiled spiral shape is something we’ve done plenty of, it’s usually been of round stock with no gaps in between. We had discussed for the past week what might be the best way to approach making these. Take round stock and flatten it out? Take square stock and flatten it out? As it turns out, the way we wound up doing it is actually one we discussed – as the most difficult – which is to coil rectangular stock on the narrow edge.
As with most coils, the start is the most critical part. There’s no fixing the taper or curl (at least very much) once you’ve started the coil. This was only a one-sided taper and I nearly forgot what those were like as most of the recent ones have been two-sided or round. That went pretty well, but continuing the coil proved to be heavy work that went much better with the stock held tight or braced up against something when striking the opposite end. One really nice thing about a coal forge is that we were able to heat specific sections of the coil to have them bend while keeping other sections cold for striking. That’s not possible in a gas forge – you have to quench sections in water to cool them off to get a similar effect.
While the concept of a one-sided taper followed by a narrow-edge coil is simple enough, the execution is another thing. Nearly every blow wants to bend and twist the piece since it doesn’t like to move on that narrow edge. And trying to keep the coil smooth and avoid flat sections is easier said than done. I found it reasonably easy to keep the outer edge smooth, but the inner edge would get some straight areas that are harder to deal with.
In the end they came out pretty well and we were able to make some small tweaks to the spacing at the end using tongs.
The last step was to work on the handles. There are lots of choices there. We could draw them out, twist them, round them up, make a tang and put on a wood handle, and so forth. In the end, Rob punched a hole through his so he could hang it and I drew another one-sided taper and made a thumb loop at the end.
This is the kind of project that will get better with practice (don’t they all). But I’d like to give this one another try and have some fun with different handles. Looking forward to cooking some bread on these!
On to the second project …
We had started making our bellows back in August but set them aside for our trip to Scotland and then the winter and then all the challenges that the spring brought. But it’s time to get them finished up!
We had left them after we attached the hinge to one set of bellows (you can catch up on that here). So we needed to get the hinge on the second set before moving on to the next steps.
Once that was complete, we moved on to getting the snout ready. We are using about a 10cm length of 2cm diameter copper tubing and attaching it to a thin sheet of copper that will sit on the end of the wood part of the bellows. We started by cutting a hole in the middle of the copper sheet that was about the size of the INSIDE diameter of the copper tube. Then we punched a few (four, to be exact) holes so that we will be able to tack it to the wood. Lastly, we soldered the tube to the sheet – something I’d never done before. It was really cool to see the solder melt and seal up the joint!
There’s still a few steps left before these will be complete. We are going to use canvas rather than leather for the sides. During the Viking-age they may have used textile, most likely wool, rather than leather for some bellows as leather may have been too expensive for such a tool. We just don’t know for sure. So we used a pattern to cut it out and that’s where we left if for the day.
So what’s left to do before these are done?
Attach the copper tube plate to the snout
Attach the canvas to the sides
Attach the handle
Treat the wood (with linseed oil)
Treat the canvas (with a beeswax/tar mixture)
Our homework is to complete four of those steps and then bring them back to the Goose Prairie Forge to complete that last, messy, smelly one to get them done. Can’t wait to see them in action!
So after a break of a few months due to the death of my mother and the outbreak of the COVID-19 pandemic, we returned to making progress on our projects. Part of today’s session was simply regrouping after the recent events, but some of it was planning for the remainder of the projects. We’ve got several things yet to accomplish and a short time to get them done, but we’ve made a plan to make it happen.
So to get back into the groove, we decided to work on a cold-cut chisel project today. It was a great choice to get back into the swing of things (see what I did there? ? ). The hammering skills were simple enough – just tapering one end of a piece of octagonal steel stock. But tool steel hammers differently than milder (aka softer) steel, so that was a good refresher. On top of that there was a bit of grinder work to do and we hadn’t been at a grinder in months. That too seemed simple enough, except you have to have a pretty steady hand to get a straight grind and we struggled with that just a bit. But after a few pointers and tips, we got the grinds looking pretty good.
So the steps to making a chisel (or pretty much any hardened tool) are essentially:
Heat treat (quench)
Chisels have a tip that has two angles on it, one that is forged in (about 15º) and one that is ground in (about 60º). So we started with forging in the taper. Then we thermocycled the pieces before we started grinding. (Thermocycled means that we heated them up to critical temperature where they become non-magnetic and then set them aside to air cool, repeated three times.) After that it was time for a heat treat. So we heated the pieces once again to critical temp and then quenched them in oil and then water. They had the nice gray color we were looking for and a file just skated off of them. So the last step was tempering the steel and we did that by heating a 4-inch length of 2-inch pipe to red hot and then holding the chisel inside the pipe for short periods of time (maybe 10 second or less) and then looking to watch for the blue almost purple color we were looking for. That means the chisel is done!
The chisel was a nice quick project that called on a variety of skills we have learned. They turned out pretty well!
P.S. We also learned about the various types of chisels. These are really broad distinctions and there’s much more to them all than this.
Hot-cut chisels: have a longer, narrower taper so that they slice through hot metal rather than push it aside.
Cold-cut chisels: have a more blunt edge to put some weight behind the cut.
Stone chisels: have a flared out edge to prevent the chisel from getting stuck in the stone.
Wood chisels: have one sided taper (they’re flat on the back).
We did it! We finished our Måstermyr chain. Well, mostly. We spent 5-1/2 hours and finished the 23 links that we had created and joined them into one chain. The actual Måstermyr chain had 26 links and a ring at one end. We will probably add those at some point, but for now we are considering this project done.
One of the nice things about making this chain was the repetition that was part of the project. For most of our other projects we have made just one and then moved on to the next project. With the chain, we got to repeatedly practice making links and then forge welding them so we started to get really comfortable – albeit still beginners – with the process. There’s a lesson there about going back and revisiting some of the projects we’ve completed previously and something to keep in mind regarding our projects going forward.
We’re going to have a bit of a break due to other commitments, so it will be a few weeks before we’re back at it again. Next up will be the completion of the bellows we began way back when and making hammers. Looking forward to having a custom-built hammer!
Today is the day when we turn from making links to making an actual chain. The thought of forging a link together while there are a couple of other links hanging off of it seems daunting. It’s often the case that we struggle to get the piece shoved into the fire as it gets hung up on the bits of coal or other obstacles. Adding a couple of links hanging off the end seems like it would only complicate that.
In addition, today was the day that Troyd Geist from the North Dakota Council on the Arts, the sponsor of our grant, was stopping by for a site visit. He certainly picked a good day! Because of his schedule we started a bit later than usual, which wasn’t a bad thing. Doug had done a nice job of setting up a table of beverages and snacks as well as a few of his favorite books, some of which we hadn’t seen before (and ordered on our way out the driveway!). It was really nice to finally meet Troyd and having him in the shop on a day when we were forge weldingweldingWelding is a process that joins metal by using high heat to melt the parts together and allowing them to cool, causing fusion.
Welding is distinct from lower temperature metal-joining techniques such as brazing and soldering, which do not melt the base metal. was a good choice.
So we started to combine our links into a chain. Take two completed links and hook them together with a U-shaped link and weld that up. Seems easy enough, right?
Actually, after much trepidation, it was pretty easy. Or at least no more difficult that doing a standalone link. The extra links hanging off didn’t really interfere with it much and sometimes actually might have made it easier as the extra weight balanced things out.
The most challenging part was not letting the join area of the link get too thin. It’s easy to want to just pound on it to get the weld to stick, but if you don’t do the overlap with enough metal it can get think in a hurry.
After doing a couple, it became much easier and we were off and running. Forge welding is hard, but it’s also a lot of fun! We got two sets of seven links put together. The Måstermyr chain had 26 links. This is going to be quite a long chain when it’s done. But making links / chains is something a person could enjoy doing a lot of – and they probably would have done a lot of them back in the day.
