Multi Position Pully for treadle to motor conversions - Free Shipping
This nifty pully is based on a 1940's design that was used after WWII while there were a lot of conversions from treadle power to motor powered machines. These become necessary when the machine is designed so that the bobbin winder is powered by the treadle belt, and not by a rubber friction tire. Having a multi position pully allows for there to be another grove where a separate belt can be set in line with the bobbin winder.
Below is a link to one of my YouTube videos showing how this works.

Another thing I want to point out is that this has TWO set screws, with grippy cupped ends on opposite sides of the pully so that if your motor shaft is slightly smaller that the hole, by tightening the set screws equally from both sides you should be able to keep everything centered.
