I got the power button and the presser foot lift bar successfully replaced on the Pfaff. Took lots of pictures and will be doing a post for Instructables on each.

As usual, figuring out how to get access to the pieces is at least 30% of the work.

Figuring out where all the bits had been when the power supply box fell apart in my hand was fun. Fortunately I was taking pictures as each part was unscrewed and had enough of them to figure it out.

Next up is the Viking's cam wheel.
