Uh-oh.
I set to cleaning Queenie (the 1924 Singer featured in this thread) today, and it turns out she suffered a major blow to the head at one point, and she has some injuries which I am not sure how to go about deaing with. Her lovely metal plate (Is it called a side plate or a face plate? The plate which is about 2.5" x 5" or so, on the left side of the machine as you are facing it to sew?), right at the top, at the first spot where the thread routing as it comes off the spool, is bent. No big deal; this is fixable, but it gives a clue as to where/how she was dropped (or where something fell atop her). Apparently during the blow, the presser foot shaft was whacked down horribly, for the her presser foot itself it bent to smithereens, and the small round plate has a mighty dent/crack from where the presser foot was whacked into it. And now for the major damage: the presser foot shaft itself is bent, near the top, and also bent is the knurled-knob-screw, which I believe is the presser foot pressure adjustment screw. (It is about 1.5 inches long, and the presser foot shaft goes through it, at the top of the machine.)
So, I doubt very much that one can buy presser foot shafts and knurled knobs at The Store.
Any suggestions? Shall I look for a parts machine? Seek to trade for parts? Make a bedside lamp out of her?
Sigh, sigh, sigh.
