Is it possible to turn a Singer 15-91 (potted motor) into a treadle? If so HOW?

The answer from a Treadleon member that I met at Cathy's is YES.
This person, who isn't Cathy or Pat, stated that they have done it.

It might be the best thing to do with some of my herd. I betcha those would treadle real sweet.

I have done it. Take the hand wheel off. You will see two large screws that were hidden behind the hand wheel. Remove these screws. The whole motor/ bobbin-winder assembly will then slide off in one piece. You may have to rocks it to get it off. All you have to do it to now slide on a spoked hand wheel. The only problem in this is you don't have a bobbinwinder. But after market combo of bobbin winder and hand wheel cover/ hood is available. I usually have these and they are inexpensive. Here is a picture of one.

Well, I just wanted it to look a little different. I wanted it to look more like the blue metallic paint on the machine. So, I first painted it a metallic blue that didn't match enough. So, then I needed to either paint it black, or do something else, and so I went with the silver. It did not come out as glossy as the sample at the craft store, despite following directions. But, that's OK. It's not great art, or a valuable antique, so it is just for fun!:thumbup:

When I get the hand wheel drilled i will figure out how to post a picture. Laura

My red head that I made into a hand crank had a mouse nest in it...ewwwwww....little fossilized mouse, too. That one cleaned up pretty good, though, and is the machine i make dolls on. Hand cranks are the best for all those little fiddly pieces. Laura

Charlee the sewing machine cabinet on Atlanta's CL is the same as my VS2 cabinet. The lid is a little different but it is basically the same cabinet. It is very interesting.

Oooo! I like that one too, but not enough to drive 8 hours round trip for!! The gas alone would cost me $100.

No, not a 301. A 400 or 401, looks like, but not sure.
