HELP PLEASE :-) Sewing Tension Question for Brother LS-590 Sewing Machine

Stupid suggestions, sorry : )

is the thread going through the tension adjustment mechanism correctly

try a new needle

is the needle rotated correctly? There's a little slot the thread is supposed to go through. It should be facing the front (or maybe the rear or possibly either side?)

adjust bobbin and top tension to right in the middle

"is the needle rotated correctly?"

This was the largest headache in figuring out my hand-me-down machine, a older Kenmore.
I had re-threaded the machine multiple times, trying different size needles, and finally sitting down and reading the manual front to back. I had missed the step where the needle had to face a certain direction. This fixed all my issues in not sewing through thicker fabrics, thread tension, and thread breakage.

It sounds like it is your bottom tension that could be off though. Is the bobbin wound properly?

It's a new machine right out of the box.

Here's what I've checked:

1) Thread is properly threaded

2) Bobbin is wound correctly

3) Needle is correctly installed (from factory) and is straight

4) Needle and thread / fabric combination seem to be fine

5) TOP thread tension is fine and has an adjustment knob

6) BOTTOM Bobbin has NO tension adjustment of its own, and seems to be unspooling faster than it should (it spins freely in the housing with no tensioning at all…….seems not right…… Operating manual only says to adjust thread tension from the Top thread adjustment knob and says nothing on how to tension the lower bobbin…..

7) I've Noticed that it is really hard to bring up the bottom thread from the bobbin for the first time. It seems to stick on something, and then after yanking on the thread till I think its about the snap it finally pulls up and spins freely..I have opened it up and there is nothing wrong or stuck as far as I can see….IT IS A REFURBISHED MACHINE. I'm wondering if its a defect….. Thoughts ?

FYI, fairly new to sewing gear myself and am not familiar with machines w/o bottom tension adjustment.

On my machine I manually rotate the "needle advancement wheel" (not sure what the technical term is) two full revolutions to get the bobbin thread to come up. If the thread shows up from below and it is too difficult to pull free, I have to rotate the wheel a bit more. If you're having to pull at it forcefully, it may not be seated properly? What is the weight of the fabric that you are running tests on? I was using 1.1oz silnylon and 1.9oz silnylon with setting the top tension to about as low as I could go with satisfactory results.

Seth, double check how/where you are feeding the bobbin thread. Recheck the diagrams in the owner manual. It's hard to explain, but the thread exiting the bobbin must go through a it's own "tensioner" that's located next to where the bobbin sits. It's usually just a small metal slit that you have to make sure that the thread passes through. It's a common oversight. My only guess is that you've skipped looping the bobbin thread through the metal slit tensioner altogether before passing it through the grey plastic "arm looking thing" out the bobbin compartment altogether.

I think Konrad's suggestion is on the mark for the bottom thread.
If the loops are in the top thread then you don't have top tension at all.

My suggestion is however very different. Find someone who knows how to use a machine and get just one lesson from them, IN PERSON. Maybe ask a neighbour; maybe you ask at a shop. Doesn't matter. One lesson, IN PERSON.

Cheers

Thanks to all who helped out with suggestions and took the time to help me trouble shoot !!

Konrad – I'm betting you have many leather bound books written about your awesomeness….You had the problem spot on and I've just corrected it and now my stitches look about 7 Trillion times better (national debt reference anyone ?) !!

Thanks to all and don't think you're off the hook forever….my stupidity knows no bounds, so I'm sure I'll be back here at some point soon crying man tears once again…

Thanks for the tip about 1-on-1 training Roger – I'll see who I can scrounge up !!

[nevermind – just noticed it was solved]
