Slowing Down a Leather Sewing Machine - Servo Motor

My website is http://www.bucklehurstleather.co.uk for high quality handmade leather belts, bags, axe covers, tool rolls etc etc. In this film I am fitting a Jack servo motor to my big harness makers sewing machine to replace the clutch motor that runs rather quickly. You will see me using a combination of a 1hp servo motor and a pulley system to slow down my big sewing machine to an absolute crawl...which is great for leatherworking.
