I have no instructions for it, but I have gleaned from my research of it that it takes a 1.5" x 25" belt. Luckily, I have a shop roll of 120 grit, 1.5" wide at my disposal. I have to figure out the best way to keep it together, but I'm leaning towards an angle of cut about 70 degrees or so, so the joined area doesn't have so much time over the rollers or platen. I'm gonna use heavy duty shipping tape and adhesive to join the two cut ends together. In combination, that should make a nice sturdy connection on the belts.
I'll keep the board posted as I get it all together.
