My diy rotisserie looks similar to blueskies. Instead of engine stands I found a scrapped Olympic weight lifting H frame. It was handy in that I could raise or lower the whole unit. I welded on caster wheels so I could move it around. With the wheels in place, each end does need to be connected for stability. I also drilled holes for threaded pins in the top of the pipe where the fork passes through. Those pins made sure that the car stayed where I put it. Balance is key. You don't want a top heavy rig. If you have the forks from the stands to the bumper mounts correct then you should be able to spin the unit with just one person. Using a 2nd person is still suggested, for safety. I pulled the car off the rotisserie to put in the drive train. Painting, brake/gas lines, wiring, etc... was a walk in the park using the rotisserie.
