I want to make a couple of dozen OAK shim/wedges just like those
cheap pine packs you pick up for door shimming. These need to stay
hard, and bear with a little pounding. They will be disposable.

I have seen a device that worked with, or replaced a fence on a
table saw, and it had adjustable angles. For cutting larger
triangular pieces.

This is not a job for a table saw IMHO.

Rather you want either a hand power planer or a router with
a 1" straight bit.

Mount a piece of 1/2" x 6" x 24" ply to the router base with a
couple of 3/4" x 3/4" 6" cleats to limit lateral movement.

Build a "U" shaped shoe that has sloped sides to match desired
taper, say 8:1 or 12:1.
