I've only recently begun collecting vintage machines. I have a couple 66's and 15's. I think I got the bobbins mixed up when I was cleaning the machines. Now I need a bobbin and I don't know which to use. Are the ones with 4 holes (per side) the same size as the ones with one hole? They look interchangeable to me.

THANKS!

Yes they're both class 66 bobbins.

if you lay them on their sides. i think class 15 will lay flat on a table versus class 66 what has a slight curve and will rock a bit.

The 15 is significantly taller than the 66 - you won't mix them up if you had one of each.

These are both 15 bobbins - and lined up with a 66 in the middle. The 15 does have flat sides, the 66 has a bit of a curve.





The 66 will fit in the 15 bobbin case, but there is a lot of room for side to side movement, I would expect that would cause tension issues. Maybe not though, I've not tired it.

Thanks everyone. Looks like what I have is 66 bobbins. I thought it had way too much wiggle room in the bobbin case (on my 15). I'll have to keep looking for the right bobbins, or go buy some .

Oh, now I'm totally going to have to try. I know you can use an L bobbin in many 15 machines, it just holds less - in theory (i.e. a prewound L likely holds more than a machine wound 15, but a machine wound L likely holds less than a machine wound 15. )

My wife used both class 15 and class 66 bobbins in her Bernina930 Record. She said it made no difference. I've tried it in several Singers and clones that use the class 15s and the class 66 bobbins have worked in all of them.

I don't do it as a rule, but when I run out of bobbin and there sits a full one, well .................

Either one will work just fine, I have some of the type on the right, came with my 1910 Singer red eye.

My Berninas 930 and 1031 are very picky about bobbins, a class 66 bobbin would cause problems because its not flat. I have about 50 bobbins between my 2 machines.
