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 weldingwelding Welding 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!
