111w155

[NancyLou]

I’m sewing webbing onto a cast net using the singer 111w155 which is the only thing in my life that gives me a hard time.   I just refilled the bobbins:  everything was working up until I did that.  It seems to go about 5 stitches then stops abruptly, and all the thread is bunched on the bottom. I have checked threading etc oiled but cannot figure out the WHY.  Could it possibly be that there is too much thread on the bobbin? You all have help me in the past and I appreciate it. Is the only bobbin thread adjustment the bigger screw shown in photo?

why is the bottom thread under the latch of the bobbin case?

Always good to read the manual fully (no offense) - I guess you have a manual, right?

Hey @NancyLou, i moved you over to Leather Sewing Machines. I know it doesn't seem quite right since you're not sewing leather, but Help Wanted is for people wanting to find someone to do a job, essentially.

I don't know why it required moderator approval. We'll keep an eye out for your next post and see what happens.

The big screw you mention holds the opener that pulls the bobbin case back to allow the needle thread to pass around the bobbin. Clear as mud, I know. I don't think any of mine are all the way forward, so it could be out of adjustment. 

Also, the thread being under the lever that holds the bobbin in place isn't remotely correct.

Let me go see if I can find one of Uwe's phenomenal videos about how to set that case opener.

EDIT: 48 seconds from Alexander Dyer will do the trick, too:

Nice photos!!

You can check whether bobbin is loaded properly before making any stitches. 

 

1. Install the bobbin and bobbin case cap.
2. Put the latch down (and make sure no thread under the latch!)
3. Bring up the bobbin thread
4. Pull the bobbin thread for a few inches. You should feel a gentle resistance the whole time you are pulling. If it snags, something is not right.
