I am looking to build a Rotisserie to put my Jag on so I can access the underside without all the dramas of hoists or lying on the concrete.

It will also make the sandblasting and painting just that much easier.

Biggest question is how much weight can the round bumper receptacles hold?

Has anyone been through this or jacked their wagon up by the bumpers?

Cheers All

You could do something like this but instead of bolting it the to the hub bolt it to the subframe mounting points

I have never done it, but (at the risk of stating the obvious) I think it would be essential to remove all the engine and drivetrain, radiators, and front and rear subframes, first.

Then, what I would do is to make a rig than utilised the bumper tubes, as you mention; but which also incorporated a very stiff frame that bolts up to the rear wheelarch chassis rails at the subframe rubber mounting points, and bolts up to the front lower chassis rails at the front subframe V mount points (rear of the subframe), and is very well braced longitudinally between these two, and horizontally across the mountings. The bumper tubes are not that strongly braced across the frame, particularly if the front lower crossmember is corroded;

The monocoque would be well supported like that, but when turned upside down, the stiffness of the rotisserie frame in the longitudinal and horizontal axis would be the crucial to prevent unwanted folding front to back, and 'banana-ing' when on its side;

I have mine on rotisserie at the moment. I used stubs of rhs welded to main support each end and these inserted into bumper tubes and are held in place with through bolt. Simple construction and very nearly right on the balance point. No problem with flex of any kind at any angle.
I should add my car is stripped body only. I think the set up would handle front and rear suspension weight but any more might be risky.

 

Here are a couple of pics might better illustrate than my words.

 

i used a rotessiore for my restore, pretty much same as baxtor, fully stripped to the body.

with all the engine,trans. frt & rear suspension and all,one would have to be very carefull on the roll over position when much of the weight transfers past neutral position!

once it starts to move past, you may not be able to hold it, could use some overhead hoists, on each side.maybe!

rotessiore is the only way, in a home garage, to do a GOOD restore project.

i have pix,but they are on a VHS tape, done in early 90s. the whole restore,2hrs long, and some of it boring, except to another restorer!

 

Thanks for the photos. Gives me a lot more confidence to proceed. Biggest mounting problem with using the subframe mounting points is the amount of steel in the way for all the future works (Blasting and Painting).

I am intending to have the car completely sand blasted and am currently stripping it. Have engine, trans, front and rear sub-frame off so far. Only have the boot and inside to strip before the blaster gets to remove all the previous owners sins.

They did a full respray back in 1995 but couldnt get it started so just gave up and parked it up where the paint blistered under the covers so I have to start again.

 

You need to convert it to digital for us tragics'. May save a lot of pondering of how to do something by someone who has done it before

 

my intension, is to give the tape to the one who buys the car, that way he can actually see what is done, mostly for the engine and trans. building and installations.

and all the welding and body work, plus the expensive paint work, all suspension ,brake mods , it seems endless!

 

Just out of vulgar curiosity, did I read somewhere that that engine weighs in the neighborhood of 700 lbs.?

 

the jag V12 weighs in around 700-725lbs, full dressed, its a heavy *****.

use strong hoist to lift one out of the engine bay, you dont want any surprises!
