Given the technology of the time I think it's a variable resistor in series with the motor. I remember the singers working but I don't remember ever taking one apart.

The inside of the foot controller was not how I expected but given 1968 I guess it's about right.

I think my above video shows that it has a huge dead space between a half press to fully pressing it down.. that's the part I don't understand hopefully google will have something about that.

It is fully oiled so it no longer slows down when doing zigzag stitches.. I'm going to be getting my mom a Brother SE400 for her birthday so this is just a fun little thing to work on now.

I think what Robbin showed is what I said.

Keep in mind that typically you has to give it more than you wanted to get it going and then back off to the slower speed. Just a phenomena of the motor control.

That's not what happens here.. once my phone is done uploading to youtube I will show you..

It has no in between at all It's just full speed or nothing at all, so the way you are saying does not work here

That machine should move the needle as slow as you want it to go.

It should but from what I can see inside the ceramic part are carbon discs which when fully pressing the switch disengages the carbon discs so it can run full speed.

Probably the discs have disintegrated over the years so they no longer work.

They would compress with the pedal giving variable speed, then the switch you see would allow full speed.

I was thinking about that since the only place I know of that had carbon discs were battery load testers.. So I guess in other words it would be impossible for it to work besides changing it out.
