The regular manual should do the job. It was posted early on this thread. If not go to Singerco and look there.

@ Irishrose Should it the Ideal brand of will it take a singer bobbincase?

@Miriam Thnx you keep giving me good advice hihi!

Tisch, I had to buy a universal bobbin case for a 1970s Montgomery Wards that came without one. It also fits a Admiral from the 40s and probably a Necchi from the same era and my 15 clone. There are basically only two types - I needed the one with the finger straight up. Check at sew-classic.com I was able to get at my local LQS for the same price with no shipping and easy returns. The brand doesn't matter - the quality and fit does.

Some of the Singer 15s have that little finger kind of in reverse of the others - kind of 11 instead of 1 o'clock.

The biggest problem with clones is when one gets in your house more sneak in to keep it company...

I don't think they sneak in, they clone themselves in different colors and names.

Per Miriam... Plain Jane. She works well, but I wonder if some of these plainer models weren't built to sloppier tolerance. Her connecting rods wiggle a few tho[ATTACH=CONFIG]431803[/ATTACH]u which makes for noise.

That can be adjusted if they are the horizontal rods underneath the machine.
~G~

Vertical front rod that drives feed dog shaft, looks like shoulder bolt and no adjustment although perhaps I just haven't look deep enough yet...?

Love these machines! I've got my eye on one right now and hope to be able to post it soon as MY machine. Keep watching. ;)
