How to make rivet rings in mail armor with home made tools.
There are three possibilities for a modern mail-maker to make a hole for riveting into the overlapping area of a ring. The most obvious modern method is to drill a hole. I advise you to use high-quality drill bits, which are sold for industry and workshops, not the usual ones from hardware stores. Besides, there are the traditional methods of piercing with an awl or punching with a punch. Especially for wedge rivets piercing is a good choice. I use an awl like the one in the picture:
I make the hole by hitting the awl twice with a hammer. A piece of
You can attach the point and its counterpart to a pair on thongs. This is worth the effort if your point doesn’t break too often. I doubt that this was done back in ancient or medieval times. However, the method of piercing can be as fast and exact as drilling and the resulting rings are very firm because no metal was removed.
For round rivets, I prefer punching the holes. This means to use a punch with a flat side facing the ring. It removes pieces in the shape of a circle from the overlapping area. I tried to forge my own punches by medieval methods two times, but it is difficult to adjust the hardness appropriately. It shouldn’t be too soft but also not too hard that it’s brittle. So I use a punch from modern steel until I figure it out.
