I checked a bunch of catalogs and engineering books. Quite a few show the
tooth profile in question. It is always the tooth flank angles, the crest
width and the tooth spacing. I assume with this, you could generate an
accurate "rack" that would fit the belts. Now, as to how to size a pulley
blank, how to allow for shrinkage as teh belt is bent, I did not see any of
that. Perhaps the dimensions can be copied and interpolated from existing
parts or derived via trial and error.

What sizes are needed?

that is the problem, we are looking for the formulas for designing the
pullies.
Hopefully the utility will do the work for any pully with a few known inputs
