So with the strap part of the spade hinge finished it was time to move on to the pintlepintle A 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 gudgeongudgeon A 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.
