The evening started out pretty good. After some labor, I was able to reattach the draw band on my Swiss Patria. I also covered the stripped roller on the paper bail with some fairly convincing electrical tape. So far, so good. Then I tried tighten the shift lock mechanism which wouldn’t hold. It broke clear off. Then I lubricated the right ribbon spool holder. It was dragging, which was affecting the shading of the letters on paper. (The ribbon was too tight.) That worked, but then a hinge that holds the ribbon vibrator dislodged. Now the ribbon vibrator won’t work. Just great. I wish I had a duplicate machine to guide me.
