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.

Not really very safe for cutting skinny triangular pieces, though....

Where can I look to find such an item or instructions? I want to keep it
cheap, safe to use, and be able to make repeatable finished shims.

Got a bandsaw? That's how I make mine, with this simple jig:

Approximate dimensions:
Front to back 8-1/4"
Left to right at the end with the stop: 4-3/4"
Left to right at the other end: 5-1/16"

There's nothing magic about the specific dimensions, I just happened to have a piece of
scrap 5-1/16 x 8-1/4" when I made this. The only really important dimensions are the length
(needs to be approximately the same length as the length of shims you want to make) and the
difference in width between the front and rear ends (needs to be about 1/4" to 5/16" to get the
proper taper on an 8" shim).

Finished shim would be 1.5" w, and 8" long, or about the same as common
softwood shims.

Yep.
