Members MarenNinni Posted April 25, 2020 Members Report Posted April 25, 2020 Hi. Help needed in Norway. I have a singer 29k51, and it worked. Until I tried using some 18/3 linen thread. The thread broke, I gave up, threaded the machine with my regular thread, and now it skips stitch number one and then the thread breaks. I have taken it apart, cleaned and oiled it, everything seems to be working, but the thread breaks. It seems to catch the bobbin winder, that's all I can work out. See pic. Any advice? I'm at loss for solving this. Kind regards from Maren Quote

Members jimi Posted April 26, 2020 Members Report Posted April 26, 2020 Hi, Sounds like maybe your needle has moved to the side?? Do you have the manual for your machine? have you checked where the needle is when the hook of the shuttle comes around?? Quote
Members LumpenDoodle2 Posted April 26, 2020 Members Report Posted April 26, 2020 Did you change the tension on the bobbin for the other thread? I have a 29K15, but it’s been ages since I had to faff with it, so not much help here. Don’t worry, someone will be along soon with better help. cheers Quote “Equality?

Will check the manual one more time. Thanks! 20 hours ago, LumpenDoodle2 said: Did you change the tension on the bobbin for the other thread?

Will try adjusting the tension of the upper thread. Quote
Members chrisash Posted April 27, 2020 Members Report Posted April 27, 2020 On the needle bar, the lower screw holds the needle in tight and just above that is another screw which when released allows the needle to be moved sideways so you can look at the hook and adjust the needle either closer or away from the hook. there is a item in the manual about changing its position Were you using the correct size needle for the thread this site may be of assistance https://www.tolindsewmach.com/thread-chart.html Quote Mi omputer is ot ood at speeling , it's not me

Have adjusted the needle bar, but no it just skips every time. I cannot see that the needle is bent or blunt, but it is an old needle soeh. It worked, and now it doesn't. *sigh* any more suggestions? Have tried adjusting the tension and checked every spring for dirt. Quote

First, make sure the machine is threaded correctly and that the needle is aligned correctly! The rib should be on the left and scarf on the right when you are in front of the arm. Also, make sure you are using the correct needle system! The original was System 29x3 and 29x4, which are obsolete. The modern equivalent is System 135x16 and 135x17 (common walking foot needles). If this is already set, then the timing of the hook is probably out and needs to be readjusted. Open the throat cover plate to expose the hook so you can see which way it needs to move to intersect the needle at the right moment. When timed correctly, the hook intersects the needle above the eye, inside the scarf area, after the needle has reached bottom dead center, then moved up slightly, then halted, or just starts to move down again. If the hook passes the needle before or after these events it skips stitches. There is a hole in the lower base, on the right side. This is a screwdriver hole. Inside there is a crank shaft coming down that meets one going through the arm, which drives the shuttle. There is an eccentric screw holding the shafts together and there is a locking nut on the back of them. It is tricky to get a box end wrench under the arm and into the lower section, but it is doable. Loosen the locknut slightly, then stick a flat blade screwdriver through the access hole. Rotate the hand wheel to bring the eccentric screw into alignment with the hole and turn it one way or the other about 1/2 turn, then check how close the hook tip comes to the needle when the needle has moved down, then up and halted. It is at this point that the hook should be approaching the center of the needle, just about the eye, in the cutout scarf. If you are using the correct needle system, aligned properly and it is set to be close to the hook, but the hook can't be adjusted to intersect it after it makes the aforementioned jog, the shuttle driving gears may have slipped out of time. That is a big deal and I won't dive into it here. If you are not skilled with repairing industrial sewing machines, contact a dealer who can repair it for you.

The needle was too close to the shuttle. When I dissasembled the gears, I took a photo of the alignment, and I checked again and it was out of time, my fault. Now it works sorta smooth, after some tension adjusting. Edited April 27, 2020 by MarenNinni Quote

I bought it second hand, full of oil, dirt and dust. Managed to restore it by manual and parts list. Skipped the gear part, coz it was sewing, until this happened. Now it's all cleaned, and after the double check also in time... Quote
