Center of gravity for a 510

Recommended Posts

I'm at the stage where I'm just about to get the 510 up on the rotisserie and wondering if someone knows where the center of gravity is on a 510, how many inches above the bumper mounting bracket holes?

I'm guessing about 3-5", my rotisserie isn't adjustable so I have to make the mounting brace right the first time.

Thanks

Here is where I mounted mine with a completely stripped shell.  Sorry, I don't have better pictures of the front and I can't give you any exact numbers, since this was over 10 years ago and I no longer have it. I'm 99% sure this was still top heavy, but not too much for one person to handle. So, you would want to mount the axis a little higher to fix that.

Thanks, that is considerably more than what I thought it would be, the measurement on the back appears to be about 9" from the top 2 bumper bolt holes to the center of the pivot tube. The front is harder to say but it looks like about 14", would you say that's about right?

 

Also it looks as if the rain gutter of the roof just cleared the center tie holding the front and back pivots secure.

The more I think about it, I'm not sure which side was heavier. I did take the trunk lid off after these pics. Clearance to the ground or cross-bar is independent of your axis, so just plan that accordingly

There's got to be an easier way to empty the ash tray.

It wasn't that, it was the french fry I dropped down the side of my seat

I built each bumper mount pivot bracket at 10", no good, way too bottom heavy, cut them up and settled at 5.5", now it's a bit top heavy  but still manageable.  I think if I had settled at 6.5" it would be a neutral spin.  I can raise the car up a few more inches to clear the roof if I need to but prefer to have  some weight resting on the rain gutter, it makes the whole rig steadier.

can you really do that to these lightly braced cracker boxes with out causing permanent warps in places you depend on for accurate suspension measurements., reinstalling glass, doors etc to make sure it goes back together straight.  I occasionally watch a tv program where a car is being restored and on a rotisserie and there are numerous braces welded to the body to keep it as straight as when it entered the shop.  I really wouldnt do this to a 510 without some cross and lateral bracing to make sure the body doesnt twist or bend.  Some 510 woiuldn't survive rotesserie without  bracing because to rust issues.  just saying.
