DIY Compound Taper Shim - Turning Fixture

HFS

Well Known Member
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.
