[ATTACH=CONFIG]451689[/ATTACH]but... stitching some cotton will eventually break the upper thread by unraveling and breaking it at the needle eye. I've tried various threads, albeit usually cheap polyester or old mercerized cotton covered poly. Same results after a few inches. The needle I had in it, was a tad longer than ones that I had in Boyes thread containers. They are 1.5" long with the center of the eye 1/8" from tip of needle. The needle that was in it, was about 1.73" long with the center of the eye 3/16" from tip of needle. The 1.5" needles are marked "40 to 60". The threads are not marked as to thickness, but I'm trying for least fuzzy, smallest diameter. As I mentioned elsewhere, there was a disc of lint that had accumulated in the end of the shuttle, same as on my 127 and 128, causing catches. Removing it helped, but I'm not sure exactly sure which needle is correct. And perhaps the needle bar height is a tetch off? Any thoughts? Thanks

oh, BTW, I wrote down that it needs 20x1 needles, is that the longer needle length. 45mm x 2 mm shank (1.77" x .080")?

And this is the little disc of lint I keep finding at the end of shuttle bobbin cases.

I never noticed that tiny little greyhound on the shuttle before!

I wonder if there's enough wear on the end of the shuttle to inhibit the bobbin from turning freely? Could that be shredding the other thread?

That's a good "tip". So it didn't look as sharp as my Singer shuttles. I used a diamond hone on it a little bit. But what was more noticeable, is that the shuttle seems pretty loose in its holder, and I can see how it could skip picking up the loop altogether.

OTOH, I guess it has to be that loose or the thread won't pass back to the rear of the shuttle. Well at least it's nice to be able to see everything!

If the shuttle is worn and has been used a lot the front point and the edges become very sharp and can cut and shred the thread. I have dulled the point along both edges of the shuttle that rides next to the shuttle race. The best thing to do is find another shuttle and boye # 5 should fit it. At least it does on my New Home And yes the shuttle has to be loose so the thread will pass under and over

If you're using a 15x1 needle it will be too short. The 20x1 is longer. Compare the needle you are using to the one that was in it, and you'll see. The numbers on the needle you are using is not the needle system number, but the needle size in diameter.

The 20x1 and 15x1 are the same except for the length. You can short seat a 15x1 so it sits out as long as the 20x1's do and it will work.

That is what I do on my two machines that use the 20x1 needles. Both made by New Home.

The New Home I had used the 20x1 needle also.

what about adjusting needle bar height setting?
