Singer 99 Hand Crank Adapter

This adapter allows the use of a reproduction Singer hand crank with no modifications to the original hand wheel.  Due to my limitations with CAD software and my printer, I was unable to get a perfect fit. I used a small amount of epoxy to mate the hand wheel to my adapter. Apply wax generously to your handwheel before assembling the parts and the adapter will pop off easily once the epoxy is cured. The clearance between the bobbin winder and the inner adapter ring is small, so be sure to tighten the two halves of the adapter ring evenly so that you avoid warping the inner ring.
