Body turn/roll

The way I see it is the only way to turn the body safely beyond the point where it 'falls over' in the direction of the turning, will have to be some kind of braking/friction system.... Am I close?

You are correct. If you make the point of rotation at the bottom of the front and rear window openings, the body will be bottom heavy. If you build a rotis like the one pictured a couple of posts above, the body will be top heavy.

If you drill through the rotis' pipe in 45 degree spaces, you can lock the whole assembly from rotating at 0, 45, 90, 135, 180, 225, 270, 315, and back to 0 degrees from level. Most all engine stands have holes drilled through the receiver for it's engine attachment mount to lock the engine block from rotating. Some have one set of holes, some have two sets 90 degrees apart.

You'll likely not be able to make this work effortlessly by going through the front and rear windows. Unless you find the body's longitudinal center and make holes through it for the rotis, it may be more than a two handed job to rotate the body.

Yeti, having holes in the pivot is a must to keep body where you want it, but you guy's need to think "outside the bug" . It doesn't matter were you mount the body as long as the center of gravity is close to pivot point of rotisserie. I've drawn a "manual cad" version (don't have new auto cad '07 loaded at house yet). The dotted line is the pivot point. You just have to find the "sweet spot" to balance the body. The tubes that attach to the pivot have holes to help "find" the center point. Pictures are better than words IMO.

We're on the same page... . I was only sacrificing ease of use for simplicity's sake.

What you have depicted in the manual CAD program ( ) looks perfect for the job. It could even be easily strengthened by incorperating the stock bumper mounts... :agree:

Hmmm.... interesting indeed!! Gad I picked the brains of you folks. Seems that this is exactly what I was after! Ijust need to get the right materials that can handle the load without bending Thanks for the input and the hard work for the "Manual CAD" version :agree:


**please ignore the "thumbs down" icon in the topic line, dont know how I managed to get that in there!!!?**

Oh yeah, I forgot to add how to find the center of balance. When you have the body on the rotisserie. Try and get it to balance on it's side (as close as possible anyway). What your doing is trying to counter balance the mounting arms with the bodies position to the pivot point of rotisserie.

If you can wait about two month's (got 4 Harley's to paint for some people first) I can show pic's of mine, and give you a material's list + dimension's (will build as cheap as possible).

Oh yeah! HAPPY NEW YEAR!!!

hmm, that would be better than my setup, and looks very good aswell, easily done with some minor fab work, id be interested to know how people go with making their own.

wrenchnride247, I was thinking among the exact same line. With help from one other person, the balance point can be determined, and the 'arms' can be marked accordingly for easy mounting next time round if it is needed again. Funny that you should say "if you can wait two months", because the way my luck goes, something else will probably come up that needs my immediate attention

AusSuper, what exactly are you after? Dimentions of the rotisserie/dolly? I can give you some dimentions of mine if you want. I should have some photos on my other PC of the build too...(I can only get to it tomorrow though)
