Question about Brother LS-2125 Mechanical Sewing Machine

The thread does not catch for the top stitch, and just bundles up underneath and turns into a big mess of threat. I was told that the tension on the bobbin needed to be adjusted. Is this right, and if so how do I adjust it

You could try adjusting the tension on the bobbin but it rarely needs adjusting.
Have you checked that all the top tension discs are clean? Often a tiny bit of broken thread causes problems. Pull a thick piece of thread manually through all of them or prise gently open and look. Take out the bobbin case and put the hoover end in the empty space to **** out any stray threads, or shoot compressed air in there to blow it clean.
Remove the needle plate and check for broken threads underneath.
Try re-threading the whole thing and remember to keep the presser foot up as you do it to keep the top tension discs released.
I have found that a blunt needle can also cause this problem....no idea why.

Have you oiled your machine recently, perhaps something is stiff. Your manual should tell you where to oil. Good luck.

I have a pfaff 1475 and i can not get the tension correct. it is very loose on rt he bobbin side and perfect on the top side. HELP


......... when you did the bobbin drop, did it drop some then stop? Is the bobbin in the correct way (can go in two ways - thread feeds differently into / under the tension 'finger')

The thread is not catching properly underneath


Try resetting the bobbin. Also check if bobbin is over-wound. Open hatch and watch to see what is going on down there. See if threads are wound around base of bobbin.

My machine is a Singer Inspiration 4210. My stitch on top looks fine at first glance but it is birdnesting underneath. What should I do to correct this?


Check your top tension. It sounds like it may be too loose or the bobbin tension may be way too tight. Most likely it is the top tension that is incorrect though. The TOP tension effects the bottom side of the stitch and the bottom tension effects the top. If the top tension isn't tight enough it won't draw the thread up through the top side taunt enough and the excess underneath makes a big loopy mess.

Viking Designer 1 balleds / Birdnest / issues after repaired from Husk service center in midwest - replaced thread needle and adjusted tension .. freequilting and embroidery situations


birdsnest refers to a mess of thread on the underside of fabric when you start sewing (after a few stitches all looks good). if this is the case and it is happening during embroidery, switch off jump stitch thread cutting.

if it happens at the start of normal sewing, either hold your needle thread when you start sewing or make sure the needle thread is under the presser foot and held by the presser foot when you start sewing. this way you will have an inch or so of thread on top of your fabric which you can trim instead of a mess underneath.

if there is a mess underneath for more than first few stitches, either your check spring in the needle tension area is set incorrectly, or your needle tension is set too loose (adjustable in sevice menu by tech only) or there is foreign matter caught in tension assembly preventing proper tension.

Thread tension problem when sewing on heavy fabrics


Sometimes when I need to use heavy thread for top stitching to reinforce a seam that has come undone, I will use the heavy thread on the top and regular thread on the bottom. I haven't tried it the other way around for hemming but I would think it would work. I do not currently have a Bernina.
