Here is the prime mover for driving the headstock.  The wood pillars are not fixed in position; other pulley combinations can be plugged in to give different shaft speeds. Ideally the surface speed on the 4" shaft will be between 175 and 200 inches per minute.


  The two small blocks on the bottom allow space for the operator's fingers. Portability and flexibility are key to the construction process.
 
The small 1 1/2" pulley is fastened to the major 10" pulley with J-B Weld. Scrapped clothes washers and dryers are good sources for pulleys of all sizes.

  The motor is a Westinghouse single phase 115 volt workhorse with a 25' cable for the remote on/off switch.
