However I found a nice lady who works on sewing machines, knows what she's doing, and fixed the whole thing right as rain for $43.
I'm so tickled to have this one back and working again!
Our friends gave this to me, complete with all the dozens of attachments that came with it (including a ruffler, which came standard!) and all the pattern cams. It's got all metal gears inside and is "ENTIRELY MADE IN AMERICA" as the manual boasts!
