Re: pic: FRC3928 2013 Butterfly Module
In this instance the traction wheel was made from a solid piece of 2.5" diameter Delrin, the Pulley was milled into the side, and two 3/8" bearings were pressed into it.
Had access to a CNC mill, decided to minimize the part count and not require ordering a pulley. -Aren |
