I've got a multi spindle drill for drilling shelf adjustment pin holes and I need a 63" x approx 1-1/4" wide, very flexible, but low stretch belt. I see a lot of conveyor type belts which would be too stiff but without a sample to put my hands on I'm not sure what I need. I would think something with urethane over a fabric core would work but it needs to be around 1/16" thick or a little thicker but less than 1/8" anyone know a good source? rollers are about 1-1/2" dia
