Anyone ever build their own plasma cutter? I've been interested in the process for the past month or so, since having a go at replacing the lower rocker/sill plate in the back door of my '97 Saturn. I used a reciprocating saw and air wheel to cut out the offending pieces and then had to reshape the new parts. To make a long story shorter, I cut the pieces by a variety of methods but kept thinking I wish I had a plasma torch.
After looking on ebay and couple of other stores for a plasma torch I thought, I wonder if I could build one and a short google search revealed a couple of different plans.
The one I thought looked most promising was by Joe Eichholz. The plasanator. He gives the plans away at his yahoo site.
I've been in contact with him and he's a nice guy. My only concern seems to be the fact this doesn't have a isolation transformer between the rectifier and the secondary winding. I'm worried about the DC OCV on this thing. It looks lethal and if for whatever reason I happen to short I'd be gone instantly.
So. I'm asking anyone with more experience than me (and that should be practically everyone). What's your opinion on this? Is it worth building? Is it even safe to build? Can I make it safer?
