I'm replacing some rusty floor pan sections and got tired of lying on my back under the car with no room to work - especially when wearing a welding helmet or face shield.
I built this "roll-tisserie" loosely based on other pictures I found online. I rolled the body up on it's side and now have great access to the underside! I spend maybe $10 - $15 on bolts, washers, nuts, lag screws, and nails. The lumber was all scraps and leftover boards from an old deck that I had on hand.
