Tomorrow I start cutting metal and building the rotisserie I should have had a long time ago. I'm actually quite eager to get going on this project, more than I anticipated. Not only because I've wanted a rotisserie for a long time, but also because once it's finished the 914 that's sitting on the Celette bench will go on the rotisserie. Then I can put a 66 912 project up on the bench and start building my first set of Celette fixtures. Even though they'll be for a 912, the techniques I learn will make the 914 fixtures even better.

I'll be posting pictures of my progress tomorrow, but I couldn't wait to share. boldblue.gif

There is no way I could have stripped, repaired and completed other big jobs without a rotisserie. It is the best tool out there for a full restoration, IMHO. Good luck with the project -- I'm sure it will make mine look like it was built out of Lincoln Logs and bubble gum. first.gif

I still don't understand how the Celette bench works. If you make your own fixtures, how will you know how accurate they are? Or are they just tools to attache to the car? Do you stretch and bend the body and then measure it with a tape, lazer, etc. till meets specs.? It'll be interesting to see the pics.
Cheers, Elliot
McMark
The actual Celette bench is just a big-ass cart. It has a regular grid of holes in the top and a machined smooth surface on top. The fixtures for different cars are bolted to the bench via the holes.

To use the bench, you lift the chassis up and attach a couple fixtures to hold it in place. On a perfectly straight car, all the fixtures will bolt up to the body and line up with their appropriate holes on the bench. On bent cars, the fixtures won't line up.

To straighten a car you bolt up the fixtures which are correct, and then push/pull the body using whatever means necessary to move the mis-aligned fixtures into place. This is the hard part because the 'operator' must understand how the damage occurred, and how to reverse it correctly. It is absolutely possible, and frighteningly easy, to bend a chassis in the wrong way and make things worse. Definitely one of those situations where 'measure twice, bend once' is SOOOOO important.

Just make sure you buy enough 2x4s before you start!

You don't want to run out. I'd also suggest priming and painting it so it won't rot.

This may be a dumb question but how do you get the 914 high enough to bolt it onto the rotisserie? Most of the rotisserie redesigns I have seen would require the 914 to be 3 to 4 ft off the ground to bolt it on.

I think it is great question, I have not attempted this, yet.

Several ways come to mind depending on what you have to work with.

A lift works really well but only a few here have them in their garage at home. I have a couple friends with shops and I could go there and put the car on the rotisserie but then I have to load the car on to a trailer while it is on a rotisserie, may not be my first choice.

A fork lift could be used but you have to have access to one or rent one. Probably more money that I want to spend.

Someone here posted some picture of an engine hoist being used to lift 1 end of the car up to get it on the rotisserie, a possibility since I have access to a couple of those. Have to figure out how to lift it without damaging the body.

Floor jack(s) and some sort of cribbing. Jack up one end at a time and stack wood or such to rest it on while you jack the other end up. going back and forth you could work it up to the right height. You have to be sure the cribbing you use is stacked stably and your jacking method is still stable as you get up off the ground. If the timing was such that I was replacing the back fence (that is starting to fall apart) I might have enough 4x4s to use for cribbing before I built the fence with them.

I also have a friend that has a couple motorcycle service lifts. They are small enough to bring 1 to my house and use it to lift the 914 body. Weight of the 914 shell would be in the range of the lift but i am not sure the height that is possible with it.

Just a thought or five

To get it on the rotisserie, just borrow a set of 22" wheels.

Put on the 22s, bolt on the rotisserie, let the air out of the tires. take the wheels off, simple.

There are designs that can be purchased or home built that incorporate hydraulic lifts on each end. Google- Direct Lift SPINS. I have no personal experience with them, but I like the possibilities.
McMark
agree.gif Lifting it manually is a great option. Also, the large jackstands can get it high enough, although slightly precarious.

Got the uprights built today, before I ran out of cutoff wheels. dry.gif
Then left the shop without getting the pictures off my camera. mad.gif

Lee,

I have the same issue and assumed "yes" since that is where I plan on mounting the rotisserie. I am a complete novice on this stuff so I figured this was a good place to start perfecting my welding and metal working skills since it would not be visible and not as critical structurally.

Here is what I found when I pulled the bumper

Here is what I have cut out, still need to grind it a bit

Here is my patch. (second attempt) It's starting to look ok. Just need to get it cleaned up and welded in.

Here is a crude drawing of what I was thinking as a solution to getting the car up high enough to spin. (this drawing is missing a lot of stuff. it's just to show my raising and lowering idea)

I know the bumper holes are the standard mounting point, and that is where I made mine for. But IMHO the best spot is the front suspension mount. I don't think I have ever seen one rotted there, it is a much more stout spot. My initial jig was intended to be a temp until I can make the permanent ones that will mount to the susension in the front and the trans mount in the rear. I plan to then make a complete under body jig to tie the front and rear together with pickup points for the suspension ears in the rear that can be used to locate the pass side when rust repair is done. By tying the front and rear together, the whole body is well braced for hell hole repairs, basically creating a light duty Cellete / rotisserie
scotty b
Put the jack on the inside. Placing it on the outside you are pushing the framwork into itself. By placing it on the inside you are lifting directly verticle on the load point. I would also recommenr using a hydraulic jack like on an engine hoist and soild mounting it to the lower leg. The set you have planned is going to be a little awkward with having to jack,set pins, raise jack, re-jack reset pins etc. A bottle jacks throw is VERY limited, whereas the tyype I am using has a long throw and can be mounted on the base and left

McMark
agree.gif Lee, you should fix the bumper mounts FIRST, then put it on the rotisserie.

Scotty, my thoughts on attaching to the front suspension/rear suspension points is that then you're dealing with a long lever arm, and lots of weight far away from the support structure. Are you concerned about this? Or do you have plans for additional support? Maybe that 'lever arm' isn't even a problem. Just thinking out loud...

Okay, pictures from yesterday. I also stopped and grabbed 16 new cutoff wheels. So I'm set for a little while. wink.gif Hoping to get wheels mounted today...

BTW, this is some 3" square tubing scrap I've had laying around. aktion035.gif
strawman
To get the body on the rotisserie, you should strip off everything possible so the tub is as light as can be. Truth be told, I still left about 100 pounds of stuff on the tub that should have been removed first -- it would have been easier to lift the car onto the rotisserie uprights had I not rushed into it.

As mentioned above, using an in-floor lift or a combination of cherry pickers/A-frame hoists would be optimal, but human power works, too. For how I did it, I first mounted the rotisserie crossbar-mounts to the factory bumper holes. See post number 17 in the link below for details:

Suby-powered rustoration

As then explained in post number 21, I used a cherry picker to lift the rear of the tub while I slid in the rear rotisserie upright, and then three of us hefted the front up while a fourth person slid the front upright into the crossbar-mount. It really wasn't that difficult -- and I'm a 150 lb. weakling! I would say six normal-sized guys could lift the tub off jackstands while another person (or two) could slide the uprights into the crossbars.

I dismounted it by myself, because I have no friends. Actually, I built an A-frame/hoist during the 27 months the car was on the rotisserie so that I could raise the Subaru engine and trans into & out of the tub (again & again & again headbang.gif ) while on the rotisserie as I fabricated suitable mounts. See post number 169 for pics of how I lowered the car back onto jackstands solo. The combo of a cherry picker and A-frame/hoist worked great.

Your neighbors are going to love you... biggrin.gif
McMark
Goeff, adding a ring to the top of your body cross member for an engine hoist is a great idea.
McMark
Got the wheels and the center legs completed. Now I need to get two more casters and figure out how to approach the rotational junction. The tube-in-tube setup works fine, but I'm hoping to see if I can find something slightly more elegant. Gotta shop McMaster-Carr. wink.gif

My thought is to use the forward A-arm mounts for the front point. That is only 10-12" ( ? ) further than the bumper holes. In the rear I plan to use the trans mount for my pickuo point. That too is only an additional 12-ish inches. ( i haven't actually measued either yet in case you couldn't tell blink.gif )

9fourteen
I am curious as to why you put the casters on the flat bar extensions versus putting them directly on the square tube. I would think it would be stronger on the square tube. Are they going to be bolted on?
McMark
Casters were from another project. If they die, I will weld new ones on. I welded angle iron on the end of the square tube because I was a little shorter on the side beams than I wanted to be, so this was my fix. If I notice those bending up, I'll add triangulation.

Part of this build is just using up crap I've got lying around the shop.

looks good.

the caster brackets look like ankle biters.

no more low rise converse in the shop : )

now you have to decide if it is faster to not strip the car down to do a repair or if stripping it down is a time saver.

agree.gif

With the weight of a car on that thing, you will instantly realize that the casters are WAY to small especially for the floor finish in your shop. Change those thing out now before you have a car on it. Casters do have weight limits. . . Tools By The Pound Harbor Freight has really nice large locking casters in-stock; CHEAP.

JMO, but you should go ahead and do that now. Or, just weld some 1/4" flat plate under the square tube and forget the angle. That looks like 3/16". I built a set of shop dolly's that bolt into my suspension consoles w/ 3/16" plate like that. The ears folded over like cardboard the first time I tried to roll the tub. I'm honestly embarrassed to admit that I did something this dumb. I'm really lucky I didn't drop the car on my feet. Be careful.

IPB Image

The 3/16" angle may hold on yours since the caster is half under the square tube, but I don't think your casters are stout enough either, tho. I had 5" 350lb casters on my dolly's and decided to replace them after moving my tube maybe 3 times. Now I have 5"x5"x1/4" plates mounted to huge 8" 450lb casters. The dolly setup is rock steady and I can move my tub easily now without worry.

Here are the casters Im using now. These are 8" and rated for 450lbs. They were ~$18 each from Harbor Freight.

Here's the updated rear dolly.

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 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
