The pulleys I am currently using look to have been cut with a profiled milling cutter on a horizontal mill or possibly hobbed. That surprised me as I would have expected them to be broached in a pot-broach. Most of the profiles don't look to lend themselves to DIY milling. > Notice the flanges are on alternate sides.
