GT parts mover.
I had a heavy duty Oxy/Acet two wheeler I got free from the dump for some time. Had no need for it as it was, so I cut the bottle holders off and made it into a two wheeled dolly. It's extra heavy duty, the axle is 3/4". Dump some slime in the tubes so it will hold air for a while. Made some cross braces and here's what I have.
Should be able to move some serious parts with this thing!
