Sorry, been gone for the last couple days.

First, it is 35 chain but might just look big from the picture.

Second, The belts are actually rubber bands. Big rubber bands. These were just samples ones we got but hopefully we will be getting more aesthetically pleasing colors.

Third, the pulleys are 2" schedule 80 PVC turned down on a cnc lathe to have 1" beveled slots that keep the rubber bands aligned. The silver end on the center pulley actually pulls out with two screws the replace rubber bands and the top and bottom have full length aluminum rods that pull out. Bushings were pressed into the PVC ends and also bolted to the vertical aluminum channel. The center pulley is driven with a window motor.
