FYI - a commercially available 3" schedule 40 pipe will fit inside a 3.5" schedule 40 pipe.  I used these size pipes to make an engine hoist, mainly because at the time I had access to scrap pipe.
Nominal Dimensions:
3" schedule 40 pipe, has an OD of 3.5", 0.216" wall thickness, ID 3.07"
3.5" schedule 40 pipe, has an OD of 4", 0.226" wall thickness, ID of 3.55"

 
Very helpful thank you. I didnt realize how close those two schedule 40 pipes were in ID and OD.

What do you guys think about adding a vertical upright to the jig I was thinking of 2" x 2"   3/16" wall  square. I was hoping to hear some suggestions on the round tube to use. I was thinking maybe the 2 1/2" x 2 1/2" sch 40 and 3" schedule  40 maybe a little over kill. My local supplier wants $189 for either size and only come in 20ft. Im okay with having excess steel. One idea I had was to cheap out and not use larger square tubing for the outer sleeve section. Instead  id use angle iron to box over the vertical upright and for my cross sections. I just was thinking I was planning on getting the 2 1/2 x 2 1/2  3/16" square and 3" x 3" 3/16" square for the main structure but its overkill for the car. If two extended engine stands can support it I can go cheap while steel prices are higher. Plus I dont need a 2,000 or more + rated rotisserie.

I only thought would be to consider buying a rotisserie that has most of the features you want, and modify it with the additional features you want.  It might take less time, energy, aggravation and money.  

Looks nice
