No long ago I lost the hand crank to my Model C, so I got a 3/4" rod about 2-1/2' long, torch bent it in the shape of a hand crank, drilled a 1/4" hole about 1/2" from the end and tack-welded a 1/4" bolt and cut it down to the size of the pin. It has been working as a homemade crank ever since.
Hope this helps.
P.S. Now if I fond my oroginal one, I'll consider selling it to you. How about that?
