Got my dad a new fence for his table saw for his birthday. Now I've decided to get him the rest of the stuff needed to really tweak up his saw for Christmas. I was planning on getting him some machined pulleys, a segmented belt and a new miter gauge. As well as a few other maintanence items. Everything with the exception of the machined pulleys has been easy to find. The saw is a Rockwell/Beaver (think it's a model 34-050; 10" contractors saw with a 22" deep top). The pulleys are labelled with diameters of 4.5" and 2 5/16". The shaft holes are 5/8" and 1/2" respectively. Anybody have any advice or sources for getting these machined pulleys?
