Default DIY Compound Taper Shim - Turning Fixture

Here is a pic of a fixture I made, for making compound taper shims to accommodate camber & toe in/out conditions at the same time.

Four set screws, at the corners, can be adjusted in two planes to resolve camber and "toe" issues at the same time.

There is a small "lug" left at the center after turning, but is easily removed - either by sawing off, then polishing flat; or, use a precision hole saw (Rotabroach) to remove the offending material.

YMMY - And probably will.

Not shown - axle mounting holes: Need to be oriented properly to yield correct "adjustment" prior to beginning turning on a lathe.

Smary setup. Wish I could add a shim to my -6A gear. The bend in the gear is off from left to right, so one tire wears more on the outside.

If your left tire is wearing more, the issue is probably torque on takeoff.
