Guy at the Sacramento swap meet sold me a homemade record lathe for $150, then said one thing that made me check every weld
He said the brass feedscrew bearing was held in with JB Weld and would probably hold for a few cuts. I got it home and grabbed a flashlight. Two of the four motor mount welds were cold, just sitting on top of the steel. Whole carriage was shimmed with beer can strips. I spent a Saturday redoing all of it with my own TIG and actual bearings. Still runs. But if I had just trusted the guy, that first warm lacquer would have taken the cutter head with it. Anyone else had a barn built machine that looked fine until you got it under real load?

JB Weld on a feedscrew bearing is nuts, cold welds I'd almost expect from a swap meet rig.
