Bobbin race - that's what I put the little drop of oil on every three or four bobbin changes or whenever my machine sounds like it's had quite a night. Bobbin race, bobbin race, bobbin race. I can never remember what that's called. Thanks Margo! Now I'm thinking of all these ways to slip that into my casual daily conversation...
So a ball point needle, a straight stitch throat place, and a bobbin race go into a bar and the throat plate says to the bartender, "You got something to fill this dent?" The ball point needle (she wasn't always a ball point you know) she blushes and starts to faint; the bobbin race spins around to catch her... No never mind, this story isn't going anywhere...
I do need a little vacuum to supplement my wisking with a brush every bobbin change.
All my life I've made the erroneous assumption that all machines needed oil...
Silly me! I need to be more careful.
