It happened to me this year that my high end Bernina was having issues, just when I was ready to take it to the shop, covid struck and the shop was deemed non-essential and closed. When I got out my trusty old vintage machine, the foot pedal fell to the floor and there was like a bakelite/early plastic insert in there that just shattered. Thrift stores were also closed, my usual place to look for a vintage foot pedal.
I got out my super low end portable Brother to make masks, and let my next door neighbor borrow my 301. Still had at least 1 working machine and one that could be working with a bit of oil and cleaning.
Feeling better about my spares...
