Which way to change my tension?

[Myles_104]

I had this exact problem with my Brother machine. I found the only way around it is to clean and oil it after EVERY project. And change the needle after 3 sewing hours.
I changed machines because it got to be a hassle

I have a kenmore.

I thought I was the only one who had this problem. I still experience it once every few projects, but it's much better. I have a Singer 5028C (nothing fancy, at least 12 years old).

I changed several things, and I *think* what (mostly) solved the problem was adjusting the way that I was winding my bobbins. My machine will thread the bobbin a little too loosely if anything is a off, from the way that the thread runs through the top to the bobbin attachment to the way that I hold the leading portion of the thread when I begin. Also, I had bought a packet of bobbins that looked like they fit, but they were actually not right for my model of machine. If for any reason the bobbin thread was anything but perfect, I had the bunched up thread on the bottom problem that you describe.

Other things that may have helped... a new needle, as mentioned above, and very careful threading of the top portion, paying special attention to how the thread catches (or fails to) in the part of the tension adjustment that is hidden inside the machine. (I get sloppy about that when I'm in a hurry -- not saying that you do, though.)

Good luck!

It's these silly new machines. I worked for years on my grandmothers old singer and never ever ever had a problem. I bought a new machine and I am constantly fixing things, getting bunched up, or breaking my thread.
