F100 twin I-beam caster adjuster tool

Has anyone ever successfully home built and used a tool similar to this to adjust caster on a modestly lowered F100 twin I beam? I'm thinking of doing it with a bottle jack or an old set of "jaws of life" I have sitting around the shop. Any idea of the tonnage jack required for the early forged axles?

 

That looks more like a tool to adjust camber rather than caster.

Your pic looks like a hookup for a CAMBER bend (axle bend).
Caster bend would be on the radius rod. Or am I missing something?

Aligned many twin I-beam Fords, but never bent radius rods. The stamped steel ones would not take it. There used to be an eccentric radius rod bushing kit available.

If you are needing a axle camber bend, a 10 ton ram will do it cold, depending where the bend point is. Your parts diagram looks like the Hunter tooling we used.

 

Of course it is camber. My brain went gonzo. sorry. I'll try a 10 ton. Thanks.

 

Instead of building the tool just call around some of Alignment shops in your area and ask if they have the tools to bend yours that way they can put your truck on an alignment machine to watch how much camber you have and need to move it should cost less for the alignment than putting the tool together. We have one where I work and charge like 70.00 to bend the I-Beams and Align but I'm in Idaho
