SINGER 15 sewing machine Model 15 Hand Crank

Description

I make this portable Folding Hand Crank that is all metal and very strong strong to add to your singer 15 or singer 66 that adds a hand crank sewing to your SINGER motor driven sewing machine without removing the motor. It's a two piece system including a boss knob that is tapped to accept the hand crank. After changing the boss knob by installing the hand crank being a left handed threaded screw when attached it releases the clutch so the motor is released and not engaged while using the hand crank. The machine makes 1 complete stitch per turn of the crank and the crank turns toward the user.
The hand crank is removed by simply turning away from the user making your singer ready to start using the motor again.
