As I intend to build my own grinder, I would like to hear what the most popular belts are (size/length? Manufacturer?) to purchase on the web as they would probably be the cheapest ones. According to the belts I will design my machine. Where do you guys buy them will also be good info. I will be glad, of course, to hear any other tip or idea in case I have not thought about something or so. Thanks a lot Michael.
