Rotisserie design

[kbee00]

I have done extensive research on this forum and others and have come across some very nice designs. However, I was not able to find the answer to my question/idea:

Has anyone just left the bumpers on the car ('79 124) and used them as the support for the Rotisserie? I thought, why fabricate arms that bolt to the bumper mounts on the car - just use the bumpers? The tubes seem plenty strong and using some U bolts to a plate on a pair of engine stands- TA DA! instant Rotisserie!!

CAn someone tell me why I shouldn't do this please - otherwise the bumpers are going back on the car.....

Thanks everyone!

you realy dont want to bend,scuff,or scrach them
the black rubber pads in front are$100 a peice and so are the side pads

So except for cosmetics - structurally they would be a good place to mount an engine hoist to make my rotisserie? Looking closely -the mounting brackets are welded to the tubes - and the tubes have a decent wall thickness ...

Anyone else want to chime in on this?

Thanks much!!

i would not trust the 4 8mm studs that hold the bumper on to support the weight of the car, i would make arms which would bolt to the bumper shock mounts front and rear ... imho

Thanks BEEK - frankly -that was my only concern after looking closely at the bumper construction.

So I could reasonably construct 4 tubes the same size as those used on the bumpers, weld them to a cross bracket and then connect that to the engine support stands.

If anyone has a design that has worked for them - I would be grateful for the help.

Thanks again

Thanks for the pic -but I can't really see anything that relates....can you explain what the pic is showing? Thank you!

Seems like I could use 1-3/4' dia tubing (matches the bumper shocks) and install them as stock. Except I could add another bolt by drilling thru - now there is no longer a pivot point. Also, remove the rubber bushing in the front and replace with a metal spacer. In the rear, there is room to bolt thru and add a bolt/nut. The extra new hole could be plugged upon completion. On the front, using the stock bracket allows for the use of the stock opening in the front valance.

I have the car stripped except for the front/rear suspension. I want to build my rotisserie first, then remove the susp. I am working outside and need to be able to move it around somehow....

The wife's car will be outside for good pretty soon....hehe (oops, here she comes, gotta go!)

i would trust the bumper shocks for the mount if using 12mm shank bolts and plates to weld on or a couple of grade 8 ubolts per side.joe

The tubing is mounted in the shouck mounts and then welded to the cross Square tube which is welded to a 1/2" 8 x 10 plate with holes to attach to the engine stands ( which have been modified for height) - I think if you do a rotissorie search, there is a thread where folks have posted pictures of how they made them.

Here's a couple of shots that might help.

Sections of thick-walled pipe the same diameter as the bumper shocks were welded to some angle iron of suitable lengths to fit into the bumper mounting points. The angle iron was then afixed to the rotating face of the engine stands.
