Tacsew T111-155 Hook Problem

[QDaddy]

My 111 was working great until I tried to adjust the presser foot height. I screwed up by changing the needle foot position in relation to the feed dog (stupid me was looking at the wrong illustration from the manual), but I seemed to get that taken care of rather quickly. When I attempted to run my first test I started getting 1 stitch and the thread was pulled from the needle. When I opened up the throat plate and removed the feed dog I see that the thread (top feed and bobbin thread) are wrapped around the projecting flange of the bobbin case holder (see attached). Everything looks great... feed timing, hook timing and the fact that it is running very smooth without any binding. It's just that the stitch gets wrapped around the flange and stops the whole process.

I really can't afford to have a guy go over this thing, so any help would be greatly appreciated.

So much thanks in advance.

Double check the threading & make sure the thread is pulled down in between the tension discs & don't forget to hold on to the needle thread the first couple of stitches.

HTH,

I just knew Cowboy Bob would come to the rescue. I'll give it a try tonight.

I found out a long time ago to start out with the basics.So keep me posted.

Threaded perfectly (needle threaded right to left as always) with good tension. The thread is passing between both tensioner and pre-tensioner disks and is not hanging anywhere. I held the needle thread and it broke the thread. When I removed the throat plate and feed dog, the thread was wrapped around the the flange of the bobbin case holder. I've tried the bobbin case holder at various positions, but have not had any positive results. I've adjusted the position of the bobbin case and hook/needle relationship as per the book. I'm at a loss.

If possible, can you have some closeup photos taken of the shuttle and its positioning bar, with the throat plate off? Take photos with the needle going down, then coming up, which is where the thread breakage occurs. Use a thin strip of leather or vinyl to give an accurate record of the problem as it develops.

Other things to check: the needle for burrs and proper alignment. Also, make sure the needle is fully seated in its housing.

Make sure that there is just a bit of play between the recess in the bobbin shuttle and the tang that secures and positions it. Too much sideways clearance might cause thread breakage problems. The actual forward/backward position can throw off the pickup point timing, or can allow the needle to hit the case, rather than pass it cleanly.

Have you tried lowering the needle 1/16" and seeing if the problem changes?

It is possible that the timing of the hook has been thrown off. It is possible that the inside foot is not coming down and lifting up at the precise moment in time needed for a full length stitch. This could possibly have something to do with your problem.

We got a real good deal on a bucn of these machines a couple of yrs ago & ended up buying 20 of them.We had a problem with the thread catching on the feed dog,so we replaced them with another style & they worked perfect.

Bob and Wiz, I've had a chance to break away from the kids to take some pretty good shots. I hope these are hires enough... if you need anything more detailed let me know. The last pic shows what happens after I try to sew. I couldn't get a decent shot with the feed dog attached, so I let it screw up and showed the results.

I've also posted 3 videos on YouTube that will show operation from different angles.

The forum will not allow me to post three medias, so just click on my other videos and you will see parts 2 and 3.

If either of you guys are in East Tennessee, I'd love to treat you to a quart of Smokey Mountain white lightning.

Change the bobbin and/or bobbin case and see if that fixes the problem.Make sure you buy the M size case with the slot to the left, like the original. Sometimes, the anti-backlash springs cause trouble. Seek a bobbin case without the backlash spring and try it out.

I don't have your make of machine and am just a beginner but,,,,, I thread my needle from left to right.
