I used to make butted maille out of stainless steel wire, which my dad wouldnt let me make it from galvanized cause he said it was "toxic". Little did I know it was only toxic if you HEAT IT UP and breath in the fumes. I also made it out of copper but it often came apart and was too heavy, also I used a mini bolt cutter to cut them and they didnt butt together that well and came apart. I spent hours doing it to no avail, I got tired of doing it and decided to test it against some arrows, needless to say it went right through. I still didnt know ALL maille was riveted except in japan, but looking through my old files I saw a pic of wedge riveted maille I saved as long ago as 2005. I just was more of a "rennie" in those days and didnt care much for historical accuracy. I would be quite satisfied with maille I'd make myself but that I am saving for when I have the tools to do it which I probably should invest in soon. Making butted is good practice to make riveted though also it's better to make your own butted rather than buy the hauberk, at least with making sleeves, I think Sir Edward made his own butted aluminum maille and it was bingo wing free. Bingo winged maille is really an eyesore for me to be honest, especially with the longer sleeves, on short sleeves it's not nearly as bad looking.
My riveted hauberk is 17 gauge, my old one was 18 which seemed kinda thin for me. I am not sure what gauge my chausses are but I am guessing either 17 or 18. I have never made my own rings for riveted maille, but if I ever do I plan to use iron wire rather than steel and find out a way to make it historically dome riveted, rather than the double ended indian made dome rivet. Or I will just use wedge rivets because they're easy to make and rivet and they're fairly strong and still period for the century I am doing (late 13th early 14th).
For now I will just settle for having wedge riveted with solid punched links, which my hauberk is 9.5 MM 17 gauge, and my chausses are 8MM and my coif is 7MM. Still need to get hand protection though, my gambeson has those integrated mittens which I was planning on modifying my hauberk to have added mittens with leather palms, with the gambeson's mittens acting as the padding for my hands so I don't have to sew padding to the hauberk.
