One purpose built rotisserie I saw on the internet was the pinnacle of engineering and is what got me started on wanting one. It was for the M151 MUTT and was probably designed for the military. It would mount the whole vehicle, complete with wheels. It has a worm gear with hand crank to rotate the vehicle 360 degrees and had a full base frame with castor wheels. The ends had a series of mounting points to allow the centre of gravity too be relocated as the weight of the mounted vehicle varied. That was a rotisserie!
I had a silo unloader winch that I was thinking of using for the rotating mechanism. I opted for simple and managed to guess close enough to the centre balance point that was quite manageable.
Bob, I would think that you should be able reason out where a box would balance. It's just basic physics. Put half the steel on top and half on the bottom. I know that sounds glib, but just sit and look at what you want mounted. Take your time, consult with your engineering team, and it will probably be close.
