Geoff Report post Posted June 26, 2010 I have 2 Singer 29k53 machines. One of them runs a bit "bumpy" and may have wear and it is hard to get a consistent stitch with it. The second machine runs really smoothly and does not appear loose anywhere. The stitching is really nice and neat most of the time. However, unpredictably it sometimes misses an odd stitch. This is accompanied by a brief knocking from the shuttle area. I have tried various tension settings, but the inconsistency continues. Could anyone throw any light as to why this is happening? Also, is there any known link to a user manual for this particular model? (I have one relating to 29k58) Any help much appreciated Quote Share this post Link to post Share on other sites
CowboyBob Report post Posted June 26, 2010 The parts are different on your machine than the 29k58 but the oper man should be the same. The machines had weak little gears on them w/small teeth that get chipped from use & will eventually break,the best way to check is lay it on the backside & take the plate off the bottom under the shuttle & look @ the gears but try to be careful thatthey don't fall out or you'll have a problem retimng the shuttle. The worst thing about them is you can't get the gears for them anymore but,they are good to keep for parts the whole needlebar end & casting will work on a 29k58,70,71&73 Bob Quote Share this post Link to post Share on other sites
Geoff Report post Posted June 27, 2010 Thanks Bob, I have checked the gears from under the arm and there is no apparent wear. I am getting a run of 6" or more of perfect stitching then a slight bump and a missed stitch. Should I look for new shuttle/bobbin? Or could it possibly be a thread tension issue? Thanks again, Geoff Quote Share this post Link to post Share on other sites
CowboyBob Report post Posted June 27, 2010 How close is the needle to the shuttle?It needs to be as close as it can get w/o touching this is adjusted by loosening the screw just above the needles set screw & moving the needle clamp to the right if needed.Also you need lower the needlebar all the way down & check that the spring up there on the leftside is touching the needlebar sometimes they are broken or bent & will also cause skipping. How does the point of the shuttle look?Is it blunt? trade w/your other macvhine & see if it works better. We stock alot of parts for these machines along w/needles & thread.

Thanks again, Geoff Geoff; Check the screws on the gears driving the bobbin shuttle. If there are any that are finger loose, tighten them as much as possible. Make sure that the sliding shafts with gear teeth are not causing the bumps. They should be held in place by the bottom cover plate, under the bobbin area of the arm. Make sure that plate is tightly secured. Also, follow the moving parts under the machine and see if there is any binding at the coupling points. Maybe one gear or connecting rod has become loose??? Check the way the bobbin is inserted into its case. It should feed against the rotation, with the thread feeding through the slot, under the little spring, through the tiny thread hole, up through the hole in the cover plate. If you can track down the cause of the bumps and fix that item, all should return to normal. Edited June 27, 2010 by Wizcrafts Quote Share this post Link to post Share on other sites
Geoff Report post Posted June 28, 2010 Thanks for your help. I have checked all round and made sure all is tight, then an application of machine oil. I placed the best of the shuttles in the machine and reduced the thread tension. The machine is now stitching a nice neat row of stitches. The only time that I have had a miss was when sewing thin leather glued together. May be the glue caused that? Thanks again Quote Share this post Link to post Share on other sites
