At what point would you need a frame jig?

[Gizmo327]

When is a Fram jig required? Do you need it when replacing the floor? I assume when tackling the trunk and quarters it will be required?

I use one any time I'm removing a panel that ISNT held on only by bolts. Unibody says it all.

i use mine on every car i do. it makes the metal process painless. and only after i put my cars on a rotisserie.

Well, ever the contrarian; I replaced the fri inner aprons, rt front frame rail, firewall and cowl, front floor, both door hinge pillars, the outer 1/4's as well as the outer and inner wheel houses and the trunk floor- on the floor or on the rotisserie. It'd probably be easier to replace things like the 1/4s' one at a time and keep the weight on the suspension as you do it. Just like in carpentry, measure twice-nay 3 times- and cut/weld once. You don't have to make this more difficult than it needs to be. Good luck

Anytime you're working on a convertible. Even if its just changing the station on the radio dial.

It would be great to have a body jig anytime major metal replacement is done but in reality you don`t really need one most of the time, I`ve seen some pretty major rebuilds using nothing more than tape measures and tram gages. As said measure, measure, measure, fit, fit , fit(adjacent panels) before melting metal together.

I'm looking at a project that might require a jig. Any pictures of what people have made. What would be the key points on the jig.

[torredcuda]

I think the ones these guys yse look pretty good, I would pick up the points on the factory chassis diagram.

That's what I need!

A mig, an eye for measuring, a load of 2" angle, HF castors, a portaband, 4" side grinder and a quart of rustoleum is all you need. I used 3" because I had some laying around.

I was looking at a car with the full quarters cut out , tail panel and the outer wheel wells removed. Guess it should have already been in a jig. Wonder if it has shifted already as it is sitting on the suspension

[MoparLeo]

You know, brain surgery is just knowing when and where to cut. It is easy to speak Chinese if you are from China. Experience ........ As said earlier, it is a uni-body construction.  Like working on a house and removing a load bearing wall without reinforcing the are first.  Feel lucky ??

Anyone who has used a jig can you PM me I have a few questions

[cuda hunter]

I have a jig.  I have not used it yet but have one.
I can get some pictures if someone needs a pic of a home made jig. 

It has been used on several known restorations.
