Cross cut sled

[dusty]

That 1/64" over 12" of miter bar engagement with the slot results in a angle deviation of 0.075 degrees.

The measured slop determined above will be much much less.

Therefore IMO bar/slot slop has a minimal effect.

Am I missing something???

Obviously!

I suggest that if this thought process is to continue it must first be determined "what level of deviation is to be tolerated".

How accurate is accurate?

My point exactly. Minuscule does not matter.

Dusty,
I said previously that I thought trying to do angles would create too much room for error. However, both SS and Rockler sleds have a movable fence for angles so It obviously can be done. How they do it and how it works re:accuracy I don't know. I am using a SS miter bar so there won't be any "slop".

UNFORTUNATELY there will be some slop with the SS Miter Bar in the Shopsmith Miter Track(s). That will not be the nice snug fit that you might expect.

As I recall, the SS literature instructs that as the sled is pushed forward it should also be gently pushed laterally towards the side of the miter slot closest to the blade. If this is done consistently, it should eliminate the effects of any "slot slop."

Yes. That maneuver does compensate for the loose fit in the miter slot (if I don't forget).

I put on a snug fitting wooden runner to ride in the other miter slot to eliminate the slop. Then, later, I built my own sled with Incra adjustable miter bars.
