Finally found the bearing setup I wanted to make the rotation super smooth. (IMG:style_emoticons/default/happy11.gif)

This also sticks with my plan to just try and use up crap I've got laying around the shop. So far I have $0 invested. (IMG:style_emoticons/default/smilie_pokal.gif)

Mark,

This is on my unit I bought it for $1100. But it has a great indexing holder when you turn the car. It makes it very easy to work on the car at all different angles. With the Jacks it makes it very easy to make the car go to the perfect working height as well. Just some ideas for you.

I'm building a similar locking pin setup.

The hydraulics are nice, but beyond the scope of this project. I have a lift, so getting cars up and down is no problem. (IMG:style_emoticons/default/sunglasses.gif)

I built my rotiserie a number of years ago.

I used a combination of 2 1/2" thick wall and thin wall tubing to allow for sliding of the tubes.

Had a local machinist bore 5/8" holes on a brigeport with 2" indexes.

Did the same thing for the slip tube except for 8" centers.

I then used two heavy wall tubes that were almost an interface fit and welded them on a plate.

Never needed a bearing. it already spins easy enough.

Turtled mine today

Built it so I could break it down and store it.

Seems to be a permanent fixture in the garage

Finally finished up the brackets for the rotisserie. Used some 1.75" DOM tubing, and 1" DOM tubing I had lying around. Works really well and all the nay-sayers from above were wrong. (IMG:style_emoticons/default/tongue.gif) It rolls just fine and its super solid. I'm happy. (IMG:style_emoticons/default/biggrin.gif)

Yeah, it's a 911. 914 fixtures are next - gotta do the floor pans on the 914/6 project.

Looks great! That is very innovative.

Now just add a motor and brakes. You already have the steering wheel. (IMG:style_emoticons/default/biggrin.gif)

I happen to be there when they were rolling it out of the shop, very stable rolled well, rotation was smooooth. Actually in person it's probably overkill, but it will last forever.

Nice job Mark (IMG:style_emoticons/default/beer.gif)

Hey Mark I've got to build another for a 911 I have coming in next month and was concerned about mounting it under the car. Does it make it top heavy that way, or does it rotate fully without trying to take off ?

It's balanced enough to handle by myself. I had to adjust it quite a bit from where I initially built it. The center of gravity is still slightly lower than where I have it. I can detail this some more if you're interested.

It's not so much where you attach to the chassis, but how the brackets align the center of gravity of the chassis with the center of rotation of the rotisserie.

Time to build 914 fixtures since my restoration project has blossomed (see link in signature). Had this big square tube already.

Started at the body and got some 7/16" bolts that were long enough to put the attachments far away from the body to allow maximum paint access. Used some spare 1" DOM tubing for the standoffs. Welded the 7/16" washers to the end of the tubing so the bolts aren't flopping around. Cut some sections of angle iron and drilled a couple holes (held the piece up against the body at traced through the holes with a Sharpie). Bolted that all together against the body and welded the standoffs to the angle iron. The square tube was too long and I also needed the bar to go a little farther out. So I cut off the excess on either end and welded it to the angle iron, then welded the remaining tube on. The small pieces of tubing were already there, so I just left them in place. But it's already strong enough for me to stand on.

My advice is to use at least 5" steel caster wheels with locks.

My big ass poly wheels SUCK. You can't get them started.

I'm going to try out the methods described in this article to find the true center of rotation. Hopefully this will avoid the guess-n-check-n-fix cycle for getting a good rotation. Plus this info would be easily repeatable for the next guy who builds a rotisserie.
