I can't remember exactly how much I shimmed it, but I think it was about
a 1/16. It put the 2 wheels into the same plane, but it didn't track
with a damn. Because of the tracking adjustment, it's not as simple as
just aligned the two wheels with a straight edge.

Bottom line, if your blade tracks well, you shouldn't need to "improve"
the design with shims.

Don't do it on a powermatic! I tried that after reading about coplanar
theory. The unit is designed correctly and tracks all blades perfectly
without being coplanar. I put washers in, thinking I was smarter than
the mfgr, and fired it up with a wide blade. No good. Removed the
washer and all my blades track well.

than not. It's just too close to be how it's supposed to be. I've
actually considered tapping new holes to mount the assembly. I could
easily mount it closer to the center of the adjustment range. Don't know
why they didn't do that in the first place.


Time to move the wheels forward the thickness of one washer....




Hmm, were the washers the same thickness? Those things are stamped out of
what ever thickness they have on hand. They vary greatly even when they
come from the same box. That's why I would try machine bushings. Any
other experiences with this sort of thing out there?
