Thanks, Matt.


I am using the correct needle system and my needle is oriented correctly.


I now feel my problem is intermittent...always the worse case. I have a really-thick test swatch, and it is sewing fine. I sew on the project, and I have issues.


I now think changes in thickness are causing me problems...moving from thick-to-super-thick, and back. I will continue to experiment.


I will have a look at foot tension, and then move on to the needle bar and timing.

Hi Roy,
Sounds like either a timing issue or that the needle bar is too high.

But first I would try tightening the presser foot tension to make sure the foot just is not popping and reducing the loop size for the hook to catch.

Also make sure you are using a 135X17 needle system and that the needle is oriented properly.

If the above does not do it then it is time to look at needle bar height and timing.

Best Regards,

Hi,

I am running a Singer 111w151. It is considered a medium duty industrial machine.

Using #69 nylon and, #19 sharps. Sewing multiple layers of 1000D nylon.

All is good until I get to the point where I am sewing through, say, six layers of fabric. Then, I start skipping stitches. It seems that the top thread is not picking up the bottom thread.

Suggestions?

Thanks,

Roy
