Hello. I am currently building a machine that needs 10mm bore 20 pitch 9mm wide gt3 belt. I can only find 6mm and 8mm on openbuilds. Does anyone else know where I could find this?
I usually check Amazon and AliExpress. Failing that, I bore them myself with drills and a small hand-ground HSS boring bar, but workholding and dialing in are sometimes a little tricky with pulleys. Much easier to get them the right size to begin with.
10mm bore is an odd size, is that a motor shaft? Powge seller on ebay is one of the best I've found and they don't have that. mcmaster carr doesn't have any 10mm bore 3gt belt sizes (it's usually called 3GT) Would have to get the 8mm and have someone with a lathe bore it. Cheers Gary
Looks like I will have to get some 8mm ID and bore out on a lathe. I bought a smaller stepper motor for Z axis and now lost the pulley that came with the kit......go figure.
