for the small belts on the faceting machines i’ve found a green belt making material on ebay sold out of china in different diameters that works great to replace belts with. you cut the length you need and using heat, i used an alcohol lamp, you weld the ends together. i’ve got two machines running with that. and cheap too as you can buy a length to make more than one… contact me by email and i can point you to that ebay item if still available.
