Chassis Jig

[VicsGarage]

So It's time to do some frame rail and tackle the rest of my body work. Has anyone built a chassis jig before?

If you have, share your photos and plans. Bonus points for 3rd gens and supporting the car by the rockers or door pillar bolts!

Find a retired Cellete bench and fixtures! They are the best you can get imo.. Otherwise your building one. Good Luck, look for old body shops going out of business or retiring.

You can look at what they use at AMD Installations.

That's cool, dadsbee!

Here is what I built. I made it out of 2"x3"x1/8" tubes mostly. I had four casters on it as well as six adjustable legs so I could set the assembly level with a laser. I made supports at the front & rear frame rails, torsion cross member, and front of the leaf springs to match the frame measurements off the factory diagram so I didn't have to do any math. Additional supports as needed for whatever I was doing.

Yep, just tacked in place. Just like the roof support welded to the top of the rear glass frame when the entire floor was cut out..

Ok thanks guys.

I think I have some ideas now..

I'll post an update when I got it worked out.

So I'm thinking of doing something similar to this guys build....



except making some clamps to hold the car at the pinch welds on the rockers for now. That should leave the most of the areas I need to work on accessible including the frame rails and door pillars....

Thoughts?

When I was building race cars we had a flat topped table. Everything bolted to it.

I made T-bolts and used the existing holes in the frame rails.

Looks good. But I need to work on my rails.

What did you use for feet?

You guys all build some really nice jigs! Impressive when you think about it!

 

[VicsGarage]

Bumping the thread again.

So I got most of my jig built... Question now is anyone got tips on how to get it up and mounted on it

Would be nice if I had a skid steer or something. As of Now... I'm thinking I have to use a engine hoist, lift one side and support it by front rails. Then go lift rear a bit and support it the same way. Using my jack stands and building them up because they will max out in height. Maybe build them up with 2x4's or something to get it the height I need.

Thoughts?

 

[SGTPaul]

Only having an engine crane, I had to get creative. So I would lift up the rear and put it on saw horses with a 4x4 across to hold it up, and then used the engine crane to lift front. Roll the jig in and out. I would now use a bigger piece of wood than the 4x4. Maybe several 2x8 nailed together?

 

[VicsGarage]

Just borrowed a engine hoist. What did you connect it to on the front and rear?

 

[VicsGarage]

Got it up now. Supported by rockers and welded on back side to lips.
