Hi all,
Here are some pictures of the chassis rotisserie for the early 911's.
I would like to say that if you are planning to put your car on a rotisserie, that you have most if not all of your sheetmetal work done and also if it's a Targa, make sure you have the body braced. I had made braces for some of the previous repairs and I used them now too.
The whole rotisserie is held together with 5/8" pins, and it can come apart easy for storage. The next picture shows these pins, and some gussets.
To raise and lower the tool I decided to use these 'farm jacks' over using hydraulic cylinders. I like the mechanical action of the jacks and raising or lowering the car can be done by one person.
I made an 'index wheel' that attaches to the yokes. By working in AutoCad, I was able to come up with a simple design that by using two brackets instead of one, I can posistion the car body in one of twenty positions. When the holes are running out on on bracket, they are just begining on the other.
Here is a picture of the rear yoke. Note that the whole thing can be taken apart. By breaking the yoke down into 'components', one person can easly attach it to your car, then you add parts to it, until it's complete.
and the front yoke.
Now, the momment you've all been waiting for, Let's get this car upside down.
The reason I wanted to make this rotisserie was to help with painting the chassis. Also later for installing the wiring harness and the suspension. But the main reason was to make applying the undercoating easier. By having the car body upside down and flat. The brush on coating will have gravity working with it instead of against it. How nice will it be to have the body like this.
Later in this thread, I'll post the dimension plans and more detail shots of the yokes, so you can build your own. I had to redo this thread because the first one had too many pictures!
Here is a link to the last thread detailing the front suspension pan replacement. From there you can keep going back and check out some of the earlier work, including a chassis jig. I'll close with a self portrait. I hope it doesn't make your computer crash.
Later, Flank.
