Hi - we are looking to produce custom pulley stock. Essentially, we'd start with a round al. bar at given diameter (we might try a couple sizes) and cut twenty tapered grooves around it. The grooves will be .50 wide at the bottom and .50 deep, with a 50 degree taper - if we change O.D.'s, the groove will not change.

We'd like to produce stock material in 8" or 12" lengths - whatever is convenient - to be cut up later. We'd start with a couple O.D.'s and do some testing, so qty would be 2 or 3 parts to start. Afterwards, it'll be a stock part for us, and we would like have it turned into finished parts once the cross-sectional geometry gets fixed.

I don't think a standard hob (multi-groove) would do it, since the O.D. isn't fixed - I think you'd have to cut the grooves one at a time vertically or horizontally. Obviously, though, I don't care how it's done.
