what year is my singer 1591 sewing machine

If you were able to pick some of these up, hopefully you've amazed yourself. Terribly dark photo, but the slightest irregularity in the handwheel shape shows you a potted motor is hiding back there. Potted motor is visible but with white tape on it, tricky. I'll report back, but I'm still curious if this will cause problems down the road.6. Right now I'm waiting for the new brushes to come in and I plan to reassemble and try it out with new wiring/brushes. If anyone has any experience with this - positive or negative - I would love to hear your opinion. I'm not sure what happens when these grooves get deep, but I suspect that it will at the very least reduce the life of new brushes.At worst could cause loss of power or a short within the windings of the motor. Both brushes were worn so far down, that their springs were cutting into the commutator, which is why I believe there are deep grooves cut into the commutator.

I tried to remove the brushes, but could not do so without taking the motor apart. It had to be completely full of black carbon dust.I honestly don't know how it all fit in there. It now turns much easier with less sticking, although I could probably do more if I get brave.Īs for the motor, the main reason for this post.Upon removing the cover, a large pile of carbon dust poured out. I then started work on the cleaning and restoration of the internals. I will find out soon enough I suppose when I get it all back together. There was a short somewhere (I got a medium shock), but I'm not sure if this was coming from something inside the motor or the wires connected on the outside. I would say 100-200 stitches per minute at most. Just to make sure it was working - I plugged it in to see how fast if would move. Prior to taking the motor apart, I started by re-wiring both the main plug and the foot pedal. The photo shows the point where the brushes make contact with the commutator. My question: For those of you who have experience restoring these old potted motors - You can see the grooves in the photo. I got to work on a restoration, having never sewed anything in my life - whether by hand or with a machine.

When I purchased it the wiring all needed to be replaced, but it does turn easily after oiling. I recently picked up a Singer 15-91 off of Craigslist and I probably over-paid for this thing at $100, but we'll see.
