Caster correcting swivel balls
I'm nearly up and running for swivel ball caster correction. This fixes this issue without hindering pinion angle created when using corrected radius arms. The jig was fabbed from .5" plate steel and DOM A513 tubing to less than .003" tolerances in my machine shop. On this first ball I noted that the mating flange was .012" out of surface flatness. This is not a serious issue but it does mean that each ball must be checked and the opposing plunge cuts for the anti-rotation inserts must be setup individually if this occurs. The .25" x .6875" inserts, machined from DOM material, will fit into the opposing holes to prevent the ball from physically rotating under heavy braking. It is an added benefit although proper torquing and use of blue locktite of the hardware should preclude this possibility from happening. The holes are elongated to provide 3.5 degrees of rotation. This is a happy medium between a 2" and 3" lift. More correction is possible for taller lifts but the insert would have to be enlarged for full 360 degree contact. Even a tall lift would benefit from some castor correction.
Retirement is great, I haven't missed a day yet!
