Picture of 201, need help with bobbin problem

The #66 did not fit. I am hoping this works as I am new to this site. You are all great!

I would recomend getting your bobbins from Sew-Classic.com. She ships out right away and her shipping costs are very reasonable.

The 201 does take the Class 66 bobbins. It was built with the steel bobbins in mind, but my 201-2 will use any of the Class 66 bobbins, it don't care weather it's plastic or metal. Mater of fact all my machines that use the Class 66 will work with any of them.

That said, the only things I can think of that would cause a Class 66 bobbin to not fit this machine is:
>Your bobbin is not a Class 66; ( Class 66 bobbins have curved sides, while Class 15 bobbins have flat sides.)
>The bobbin is bent or somehow defective; a very definite possibility with some of the cheaper brands.
>There is something amiss in the bobbin carrier; lint, debris, thread, misalignment (?)

Sew-Classics does sell good bobbins.

I'm looking at my pack of four Singer brand 66 bobbins and they do not fit either of the Redeyes or the 201. They are too big across. Plastic 66s fit. Vintage metal bobbins fit. I have 18 machines, all of them working. Sew-Classic is temporarily out of stock on the good metal bobbins.

redmadder,

Sigh .... there's the rub, most of the Singer parts are made in China. They probably took the "inch" measurements and rounded them up to the next largest "millimeter". That's fine if you're building a B-29 Super Fort by reverse engineering like the Russians did during WW II, but for parts used in "inch" made machines it doesn't always work.

I'd suggest returning them to where ever you bought them.
