I finally fabbed a body cart to roll around the shop without the extra length of frame in the way all the time. After seeing how blue69 (
this thread) flipped his tub, and looking for more ideas, I took from toplesskayfiver's design (from
this thread) for arms to flip the whole assembly on its side. I have all my measurements written down if anybody wants them to build one of their own. Apparently undercoating and grease don't get along very well. A few leaky seals have made the scraping operation incredibly easy in the affected areas.
