Hey Guys , sorry for the delay. Don't know how I missed this one.
Anyway, mine is very close to that last one only as a full round circle. But I kind of like the idea of the multiple sides , easy to make at home and let's you stop it where you need to. But then mine is easy to stop anywhere too with a block of wood . Also with it being round , if you put a piece of pipe on the floor then roll the hoops up to it you can in effect roll the vehicle on the spot rather than have it travel across your shop.
I had my two done at a big industrial tube bending place in Langley.(cant remember the name, there's a few out there) About $150 including materials 10 years ago . Thats for two 7 ft dia. full circle hoops . If I were to do it again I'd only have one made then cut it in half because I don't think I've ever gone past half way around . I made up and welded on my own brackets .
Gerry , I can imagine exactly what your thinking, a flat bar across the bottom for the body to sit on. Either the heater chanels or the bumper brackets . Or , with the pan on , bolt it on to the trany frame horns and where the beam goes.
Sorry , no pics but your all welcome to stop in and have a look.
