Jimbob Report post Posted October 22, 2012 Having problems....with super loose bottom tension.....on my Singer 211G-155... Seems that the bottom tension is so loose, I cant hardly use 69 on bottom...tje spring loaded tension screw is all the way tight....if I use 138 on bottom it is much better but still on thinn material the knots showing on top every now and then.....I have virtually no tension on top just to be able to sew......seems this just happened latly.... If I use 138 top and bottom, on at least two layers of 3-4 oz I am sewing fine....wonder if anybody has hints to this problem!? Thanks James Quote Share this post Link to post Share on other sites
Wizcrafts Report post Posted October 22, 2012 Insert the bobbin so it feeds backwards to the slot in the case, or replace the bobbin tension spring. Also, make certain that the bobbin thread is actually passing under the tension spring on the way out of the case. Use the smallest needle that allows the top thread to feed. That might be a #21 for your #138 thread. Tighter holes make for tighter knots and this may alleviate the problem. Quote Share this post Link to post Share on other sites
Jimbob Report post Posted October 22, 2012 Wiz tnx for the info and advice....the needle thing struck me, makes sense if the holes are to big, the knot is loose and may slip up or down....I am real lazy about changing needle sizes.....will try spring replacement....bobbin direction is ok, feeding under tension blade also! I am gonna try to use smallest needle for the No. of thread I will use next time.... Again, thanks a lot for helping out... Jimbob Quote Share this post Link to post Share on other sites

gottaknow Report post Posted October 23, 2012 Wiz has some good advice there, so I'll add just a bit. It's very common on those baskets for the tension spring to get fatigued. For that matter, it happens in newer machines as well, more so on machines with vertical hooks like your 211. You can remove the spring by taking out the adjustment screw and then the anchor screw. Gently reshape the spring so it's a tighter "C" shape than when you started. It doesn't take much. You can buy yourself some time as the spring will need to be replaced eventually. I magnetize most of my screwdrivers to hold on to the little devils, and also for restarting them. I have about 60 of those machines in storage, so if you need an uncommon part, let me know. I have an extensive parts inventory. Regards, Eric Quote Share this post Link to post Share on other sites
