The rotisserie? Sure!
The uprights are made from 90x90x4mm square tubing, the sliding post and tie bar are 80x80x4. Rotator head is mounted on trailer wheel bearings, 100x4 bolt pattern. The rotator beams are made from 50x50x3 tubing; the sliding sleeves for lifting arms are 60x60x4. Lifting arms are 60x40x4 mounted on flanges made from 120x50x4 L-bar. The parts with threaded rods are adjustable feet; the rotisserie can be set perfectly even on uneven ground. If I ever get a proper garage to work in, the pads are easy to swap to wheels. A detail not shown is the rotating mechanism; sandwhiched between the rotator head and the bearing is a motorcycle rear sprocket, and the pinion sprocket is on an angle drive. It works reasonably well but required the car is at somewhat balance in the rotisserie.
There is a design flaw (or a bad decision) in the construction: the lifting arms are only adjustable in span. They should have vertical adjustment sleeves too, the car is too bottom heavy to be rotated upside down (the rotator would probably break at 90 degree tilt) so anyone replicating the design take note: make the arms fully adjustable! Also, the actual lifting brackets would be more versatile if they're made like the holding brackets in engine stands. I'm going to have to fix that at some point.
