Oh my goodness - I did it!!
The light comes on, but nothing from the motor. However, I have *never* had anything to do with a knee pedal; could totally be operator error. It looked like the hinge was broken on the faceplate, but my 13 year old got it on. It is discolored =(( and dirty. The fabric scrap had nice stitches in it . . . The cabinet is beat up in the back, and the veneer is peeling off of a drawer.
When the motor didn't work, she knew that was bad. I remembered what Miriam said, and told her that the machine was probably worth $5. That I didn't need the cabinet really. She said to make her an offer, and I said what's the lowest you'd take? My kid said, oh . . six or seven? So I said, maybe ten or fifteen? And after we'd tinkered some more trying to get the motor to come on . . . She said she'd take ten. I was so tickled.
Then, when I got home . . I found all this. I am afraid I cheated her . . these attachments . . wow!
