One of the best things to cast these short of parts out of is defunct automotive carburetor bodies it is a zinc alloy and this what so many of these old pulleys where made of. The alloy used in carburetor bodies has a 350 degree lower melting point then aluminum, they cast to a fine finish requiring very little if any finish work. The problem, of course, it the cost of setting things up.
