Bottom thread is good, but top thread is wrong

Kgg: what’s the drop test for checking bobbin tension? I’ll try and find a video on it but I haven’t heard of that yet thanks! 

I'm not @kgg but I'll try to answer your question about the bobbin drop test...

Hold the bobbin in one hand and the thread coming out of it in the other.  Let the bobbin go while holding onto the thread.  The bobbin shouldn't drop.  If you "gently" bounce the bobbin the thread should come out of the bobbin.  It shouldn't be too hard to get the thread out but neither should it be too easy.  This takes a bit of practice.  Once the bobbin tension is set correctly, the balance of thread tension adjustment should be on the top thread.

By the way, if you want someone to be notified that you've left a reply for them (as you did above), you need to type the "@" symbol and then start typing the person's name.  Pick the right name from the list that comes up.  Unless you do that the person will not be notified there is a reply for them and will only see it if they happen to visit the thread again.

Awesome thanks! I’ll try that this evening and thanks for the @ tip!

It’s doing it again tonight and I have noticed that the bobbin when set and coming up thru the feed dog hole, is very loose. Like no real tension at all. The top thread has tension. My question is, how do you tighten the bobbin tension? The only thing I remove from the bobbin assembly is the bobbin itself, so I can’t do the drop test. It just falls straight to the floor. Something is off. And there’s a great chance that it’s me!

What machine is it?

I think you have a Singer 111w 153 machine according to one of your previous posts. Go to your manual page 14 it will explain how to adjust the bobbin tension. If you don't have a manual I have attached a pdf. of the manual as well as better / clearer images of those pages from that manual.

Also here is a link for a needle to thread size chart: https://www.tolindsewmach.com/thread-chart.html

A #22 and #23 needle are for V138 in thinner items or with V92 in thicker materials. You would probably have to move to a #24 for thicker materials with V138 thread.

Now we have a clearer idea of what the machine may be , which does help. It may be easier to remove the shuttle to adjust the the tension . From experience,( on my Seiko)  its a little awkward to adjust it while its still in the machine, but it can be done. I have had thread break on the thread guide #15 .

That’s about where it’s breaking on mine. I don’t have the small thread guide that’s on the needle shaft which I think is #16. I may need to try and find one somewhere. But I feel like something is off either in the bobbin or in the top thread that’s making it sew like in the picture.
