Singer 211G155

I have a used, well used Singer 211G155. At times, I spend more time removing the rat’s nest of thread I create. I am novice. Any advice to reduce the number of rat nesses is appreciated.

Hi thiesfer, make sure that you hold the 2 threads for a couple of stitches when you start sewing. Also make sure that your tensions are not too loose. Thanks, Steve

Steve,

Thanks for the reply. I will look the bobbin tension and needle thread tension controls. I have manual and can see the two controls. I am not sure if they tight now. I will experiment.

I don't if this is relevant, but I get my rat's nest at times after 3-4 inches if good stitches.

thanks!

It is very relevant! It indicates that your top thread may be coming out center of the upper tension disks and is just riding freely through their upper edges, which taper away from each other. This in effect leaves zero top tension and 100% bottom tension, hence the rats nest under the work.

Make sure that the top thread is looped around the multiple thread guide post holes and exits the lowest hole inline with the tension disks. Pull it into the disks, then around and out of the check spring disk, up to the take-up lever, and down to the needle. Watch the top thread in the disks as you sew. If you see it jump out of the middle of the tension disks, pull it out and wrap it around the guide post one more time.

This would have to be a very rigid thread if it is able to jump out of the upper tension disks. Perhaps your top tension may be so tight that the thread is forced out of the middle. Try reducing both the top and bottom spring tensions to half what they currently are.

Thanks for info. I will proceed as instructed. Thanks!!!!

Another thought. If indeed the top thread is jumping out of the top tension disks, it may be caused by the shock of take-up and not enough slack in the check spring. Try lengthening the stroke of the check spring (loosen hold down screw and rotate the limiting bracket counterclockwise, that controls the spring's bottom resting position, to lower it). Or, add a bit more pressure to the spring thread guide by rotating it's shaft clockwise (loosen a set screw in the body, turn split shaft clockwise with flat blade screwdriver, tighten the set screw).
