I used some extra/scrap angle iron pieces; stripped everything off an old gas powered push type lawn mower deck except the wheels, turned it upside down, welded four vertical pieces into it, then welded a rectangle of angle iron on top of those four vertical pieces. Welder sits in the rectangle, helmets, clamps, brushes, etc stashed in the deck down below. I bent a piece of concrete reinforcing rod and welded to to the rectangle frame to use as a handle.
Might should have fabricated some sort of rack and pinion steering mechanism; maybe installed a reverse gear system.
