Tips: Just because a seller says it's "heavy duty" doesn't mean it is. If "fashion" or "stylist" is in the name, it's probably for light sewing.
Just because it's all metal on the outside doesn't mean it is inside.
Just because there's some plastic outside doesn't mean it's plastic inside.
Just because it CAN sew through thick leather doesn't mean it can do it exclusively for years (vintage/antique industrials exist - get one of those if you're doing mostly leather).
@Agatha yeah, sounds like you have a parts monster there. Good luck!!
@Agatha You know what, I'm wrong - it wasn't a 457. It was a 237. Mom bought it when I was a baby, 1969, so I'm guessing it was one of those made in Italy. All metal body, weighs a freaking ton.
That one is *nearly* identical to the one I just tore down, but without the nylon gears. Definitely a better version, imho. I used the 237's (and the 347's) parts diagram to help me tear down the 457, as I couldn't find one for a plain 457. There are a lot of parts diagrams out there for OTHER versions of the 457 (G, K, U), but they are actually way different.
And I called this 457 a Fashion Mate when it's a Stylist. π Same difference, in the end.
@kismatt
I'm glad! I just stripped one down for parts. π I'd hoped to just replace the bad cam, but it has electrical issues, too. I got it for $5 (the attachments & Singer-specific thumb screws were worth that much), but it'll just cost too much for the value. It needed a new bulb, pedal/power cord, and spool pins, too. A $5 machine is suddenly going to cost $100.
