I have a buddy who owns a tavern and several of his bar stools have become victim to some of his more overzealous patrons. He asked me if I could take a look to see if I could fix them here's some pics of the first one, it's pretty representative of all 12 stools he brought me. The material is t-h-i-n thin! ran a few beads on one that was "beyond repair" and found that I'll need to run my TIG at 30 amps. More pics once I get some welds complete.
