Rotisserie or Rolling Cart - Pros and Cons
I had to build my own rotisserie.
1) At the time, I didn't know how to weld yet, so I built it out of wood, and
2) I had a low ceiling garage, also with an opener and I wanted to be able to rotate inside, and be able to get through the door while vertical. I also had a crappy driveway, so I needed wheels big enough to get through the cracks and chips.
I put the longitudinal "bars" on either side, rather than one down the middle, so the car body could dip down as low as possible. I did have to crank it up a couple inches for those times I wanted to roll it over past the roof rail/gutter corner. It cost me about $120 to build, but that was before wood prices went through the roof.
Trying to attach a couple pics, but having issues, I'll get back to it later.
