But with so many 15s out there why would you want to do it to a 91?

It's a piece of cake to make a treadle or a hang on motor machine out of a Singer 15-91.
I've done it as an experiment.

First, disconnect all the wiring.

Second, remove the hand wheel.

Third, locate and remove the two screws holding the potted motor assembly on.

Fourth, clean the front of the machine.

Fifth, acquire a belt guard/bobbin winder, hand wheel, stop motion knob and washer, and motor with mount and light if you want, from a clone. The clone's screws that hold the bobbin winder/belt guard on will fit the Singer.

Sixth assemble in reverse order, plug in and sew up a storm.

If you go to Sew-Classic she has the belt guard and hand wheel for the conversion to hand cranks. She may also have the screws. That's really all you need to convert the Singer for treadle use.

Here's my 15-91 converted to be a Frankenstein machine:

The loaner machine is in the rear.

The two screws needed to mount the belt guard/winder should be available from most Singer repair
shops.

It can be hard to find the screws and NO sew-classic doesn't have the screws

Still doesn't answer my question. Why frankenstein a 91? When there are so many 15's.

bad wires - frozen up motor - I've seen some real gems around here - yup it was better to pull off the motor and put something else on it

Cari,
some times they look pretty bad and it is easier to convert than to put a ton more time in an already bad project...

yes it now runs just fine - yes it was covered in rust and grime
no the motor was not worth saving
yes you see black chrome

I forgot to mention you can use parts from a regular Singer 15 to do this also.

The machine I used in the pics above was a total mess. Rusted, coated with a black carbonized gunk that took denatured alcohol to get off ( hard on decals ), the wiring was a dangerous mess with petrified and gooey insulation on it.
I paid a whole $10.00 for it for the express purpose of learning how to rewire a potted motor. I did it, I got it all cleaned up, rewired and it sews just great. But it's still too ugly, and I've got too much time and effort in it to sell it, so it is one of our user machines.

It would have been far easier to convert it to a regular motor machine like my experiment, or to a hand crank or treadle machine with parts from another derelict machine.

I think I ended up throwing out quite a few parts on that machine - a donor and a belt guard from Mizkaki gave it some new life though. I can see that it could use some more clean up. There is always something on some of them... I probably gave up on it or ran out of time. I've learned a lot since then from Glenn.

HHHMMMM I think I need to go back over that machine. I think it could be improved a lot!

Good point, but I was thinking lighter weight for easy mobility and for moving it around for taking classes perhaps.
