I don't know if anyone would be interested in this, but I saw a pretty nifty DIY spot welder that in material costs rank it just above free and just below a case of beer. http://www.youtube.com/watch?annota...&feature=iv&src_vid=GCrqLlz8Ee0&v=vrlvqib94xQ
Wow! I wonder if that guy's initial s are "HF"? Seriously, that looks like some I might try in the summer.
Oh boy, now I'll have to find an old microwave so it can sit under my bench until I get around to making a welder! Pretty cool.
Wow, I'm ALL FOR low cost home-built stuff, but, I don't think the juice was worth the squeeze on that one.
I think this is a whole lot easier and more effective too http://www.harborfreight.com/115-volt-spot-welder-45689.html
