This motor pulley is designed for our DC motor with a 5/16” motor shaft. It is not compatible with our older AC/DC motor that has a 9/23” shaft, which we discontinued in 1993.
Spindle “Tommy” Bars are use to aid in the operation of opening and closing scrolling chucks and in the headstock spindle to provide leverage when unthreading tooling. They have a diameter of 5/32″ and are 3-1/8″ long.
