Hey, I'm in the SCA and I ride a Triumph, so how wierd can "they" be???? Though I only go to some stuff.
If you search on making chainmail you are sure to find sources, most likely posted by helpfull SCA folk. Not hard to do, time consuming, tedious maybe. Buy wire, wrap on rode with drill, cut spring like wrapped wire, attache rings together, clamp with pliers etc etc etc. Knew a former marine who makes it, hey if a jar head can do it.....
Just kidding. THANKS to all who have and do serve......BTW Happy 4th.
