For those of you that have used them in the past. This is what I have come up with and wanted to get some feedback before I mount the car, in case I missed something. First, the parameters. I wanted to be able to lift and lower the car using the rotisserie, so I can lower it back onto jack stand when I am not working on the car. Also, I wanted to be able to break it down when I am finished. The construction. All 1/4 inch wall tubing, 2X6 crossbars, 2X3 wheel/supports, 2.5X2.5 vertical. I first made a 2.5 square hole in the bottom of the crossbar to slip fit the vertical post, then made a clearance hole in the top side of the crossbar. I made a small 1/4 thick plate to slip fit the vertical post that I welded onto the post, square, and high up the post enough that when assembled the post sticks through the bottom of the crossbar 1/4 inch. Then I made a large 1/4 plate that also slip fits the vertical post. I made this for two reasons, first so when I tap the crossbar for mounting bolts I would be threading 1/2 inch of material, second I leveled the crossbar first, then put the top plate in place, then dropped in the vertical post and squared that up, then welded the top plate onto the crossbar. That was the easiest way I could figure out to square up the vertical to the crossbar. Then drilled and tapped the crossbar/top plate to bolt down the vertical post and the hi lift jacks. Then made the vertical slider with indexer. What you do not see. The second assemble, it is the same but without the indexer. I have the bars and mounts for the body on the car already, I got these from another member . I have a couple on dowels made that I will put through the holes in the hi lift jack lifting bar, in case of some sort of failure while using the jacks. And I will add some adjustable connectors to connect the front and back assembles so they don't try to move independently from each other. Anything I overlooked ?
