No, is a pain in the ass bigger than a mountain.
Although I want to do a 6x6 chainmaille riveted, but in the future.
Actually, you don't even need a welder to rivet your chainmaille; you have to hammering your rings, then, with a… hole punch? (I don't know what's the name in english; the shit to do holes in metals) you do a little hole in the ring, where the binding of the ring is, and then, with a little wire of metal, you put it, and hammering again to rivet. In both sides.
This will take you more than 6 month… I guess… maybe more, maybe less; anyway, is a pain in the ass.
But only magoya will open it. It will resist arrows, too.
