Someone found an old wheelchair the other day that had been dumped and they turned it in at the firestation. I got to looking at it and I think it would make a pretty good welding cart. Take the vinyl seat out, replace it with some steel for a shelf, add a drawer and some do dads for cord holders, rod, ect. and I think it will work fine. Plus its got some really good casters and sealed bearing wheels with brakes, it rolls like a dream and turns on a dime. Might even make it to accept my plasma cutter also.
