Next put it on a treadle belt etc - it will work with out a bobbin winder if you use a sidewinder. I'm thinking the hand wheels are not all the same depth so you will need to find some thing that interchanges.

I don't believe that the 15-91 handwheel, clutch assembly and fiber spiral gear can just be removed from a 15-91 and replaced with a spoked handwheel. Johnm
