Singer 320K2 bobbin case mod

Don't you love a mod? Ah the '60s... No that's a different kind, but this one's more useful than stylish.

Here is the bobbin case after Nick Ciancio did his thing:

The arrows point to the bit he machined off. I asked him to explain the mod and he said that when there's a 15x1 needle inserted, there's no problem when straight stitching. When zig-zagging, however, there's a real danger of the needle hitting the bobbin case, and the removed section marks the point of impact. The longer 15x1 goes down an extra 2mm or so and removing this by making the "U" shape a little wider (see arrows) removes the possibility of impact.

I now have an extremely rare old machine that has a free arm and uses common 15x1 needles! Allowing a 15x1 needle to punch the metal out is a bad idea. Just Google for the result and you'll find pictures of destroyed cases.

I'm more than happy to recommend Nick to anyone in Melbourne who has a vintage machine. He's very friendly, can repair anything and really loves the old machines.

Oh and I should mention that in a comment on my last post I said that I was a little disappointed in the 320s stitch quality. Checked the needle height and it was a mm or two out, which had also put the timing out. Spent 20 minutes fixing it and she sews much better now.
