15-91 convert to hand crank?
I have someone interested in buying a machine, but the person wants only a hand crank. I have several 66s to pick from, and a couple of 15-91s, and I'm wondering if anyone has converted a 15-91 to hand crank and what's involved in terms of additional parts, other than a spoked handwheel and the crank itself. If the person shows up they may be just fine with a 66 but if a 15-91 can convert I'd like to offer the option.
I haven't had 15-91 apart for quite a while, and am having trouble picturing it apart, and the workbench is full up with machines and parts in bins already.

The 15-91 is a fine machine, with that potted motor.
I would let hem look at the stable of 66s, and pick from those. The 66 is a lighter running machine, and will handcrank easily. Whike the -91 can be handcranked, it isn't suited to that as well as the 66.

This drive is from a 201 and I think the 15-91 may use the same pieces

The hand wheel has a spiral drive on it. The bobbin winder will go away, and the 3 lobe clutch disc is different. I started the conversion and am head scratching now.
66 is far easier.
