The big problem is finding a shuttle. I was wondering if anyone has "converted" a White with the shuttle with the spindle and hollow bobbins to using a hollow shuttle with solid bobbins. I would think this is possible as long as the shuttle is the same size. I still can't find the one I had, I think it got in some of DH's "parts" stuff and may be gone for good. My DH says I'm not to buy a treadle machine and hope I can get parts so I can sew on it.
