2"x2" idler wheel used in the KMG Rotary Platen
2" by 2" idler wheel is machined aluminum with bearings in place to mount on a 1/2" shaft. This wheel has grooves milled in around the circumference and is used in the KMG Rotary platen. Use these 3 or 4 of these wheels, along with a "J" series, 20 grooves wide 26" long auto belt for your own rotary platen design and construction. I do not currently have any plans for building a rotary platen.
