Now that would be absurd, wouldn't it?

You wouldn't want to bet $20 on that would you?

For education purposes only:
"Fine adjustments to the angle of the fence mounting bracket to
your table top can also be made by loosening the same fasteners and placing a paper shim between the bracket and the underside of the protractor."

See the last sentence of item 5.

IMHO a paper shim is NOT an adjustment! A band aid maybe.

All this is dependent on the amount of lift the nylon glides on the bottom of the miter gauge have. They are a fulcrum point and the miter bar itself limits any rotation.

If a paper shim is effective, would not adjusting the glides be a more effective way to 'do it'?

Maybe you should send a resume to Incra Engineering.

Well you certainly have me confused, it sounds like we changed subjects from my quote of the incra manual of how to adjust the angle of the fence mounting to something different.

One of the complaints focused on the fact that the part which I believe is called the universal fence mounting bracket was not at 90 deg. (vertical) to the table of the shopsmith. This part from the pictures is mounted by 4 fasteners to the protractor head. The place where the two parts meet is the only location any adjustment can be made... either paper of foil placed at the correct location will adjust that angle.... There are no other ways of doing this provided.

On to other subjects................................

The other thing I missed when I first looked at this is the method of locking the miter bar in the slot... a different method but still the same idea as the regular shopsmith miter gauge. That makes it a good deal more useful for everyday work!

Sorry! My BAD! I did not follow the subject properly through the post maze.

I also noticed the bar 'slop' adjustment method. Looks effective. GEE wouldn't it be nice if incra made a 'universal' bar that would fit a ss slot that had these devices. Wouldn't be too difficult since they ARE now making a V120 version!

Oh-oh. Looks like it was moi whut caused the unintentional confusion.
I'd just been considering what possible reason anyone might have to finesse the vertical of the face of a miter guage when I re-read those .pdf steps 4 & 5. The end of the step 5 on my screen reads "Securely retighten... to complete the alignment."
I took them at their word.

But beside that, on my MG making the as-is face square to the table top is not only unnecessary, it is impossible, even reverting to a piece of paper shim (that will work at all angles?), as the unit now stands. The face is flat horizontally where it needs to be, but not vertically where it doesn't matter.

But if one were to add an auxiliary face and wanted to finesse the vertical, playing with shims per INCRA-- as Ed mentioned and I missed-- would seem to be the way to go, I guess.

I cannot lock the miter bar. Tightening the screw still allows the bar to slip. I have found that removing the rubber o-ring is required in my situation. I have flipped the retainer but that does not help. Any ideas?

If you want an Incra miter bar, they are available as replacement parts.

I can make mine harder to move by adjusting those screws but I can not lock it. I don't believe that the designer had "locking it" as a design requirement. The mechanism does do a fantastic job of taking the wiggle out.

Locking the miter bar in place is an occasional requirement. Easily resolved!
Don't get rid of the old miter gauge.

I have relocated one to belt sander and the other to the Crafter's Station.

OK, again read the information that Incra provides:

"Place the Miter V120 in your Shopsmith’s miter channel. The T-slot
retainer has a rubber O-ring between the retainer and the underside of the
bar to permit tightening the retainer to lock the Miter V120 into your miter
slot. This will allow you to use the Miter V120 as a guide for horizontal boring or disc sanding."

The design intent is to lock it in place. As you read farther it mentions that if over tightened to flip it over... if it is still not working then I would contact Incra and talk to Mark. It could be they have a material or design problem???
