This sewing machine was my Dad's and I was getting it ready to go to my nieces. I believe when I made this video I was waiting for the new motor to arrive. This is the same way you would convert most Singer 66s, 99s, Spartan, 15s. Reproduction hand cranks and spoked hand wheels can be found on Ebay:
