calves4u Report post Posted March 31, 2012 We purchased a 29-4 singer leather sewing machine, tore it down and cleaned it. It is back together and won't stitch. I'm relatively certain it is threaded correctly, but the bobbin won't catch the top thread to make the stitch. When we first bought it it did stitch. The little pin that holds the needle plate in place was broken. In replacing that we decided the entire thing should be torn apart and layers of grease and dirt scraped off. Any light you could shed on this problem would be appreciated. Jeri Quote Share this post Link to post Share on other sites

Jeri A couple of things that cause loss of stitching are a bent, broken, or missing thread check spring (in needle bar, just above the needle mounting block), loose or incorrectly positioned shuttle drive gear, a broken top of a needle inside the needle mount, or incorrect threading path, or the needle inserted backwards.

We have checked all the suggestions you gave but don't know for sure how the gear drive goes in. It was the only thing we couldn't find a good picture of.

Vincent Report post Posted April 17, 2012 I could use some pictures also. I found some technical information on the Adler machines, needle bar height stuff like that, the things that a repair person might need but I'm not sure if it applies? Quote Share this post Link to post Share on other sites
CowboyBob Report post Posted April 17, 2012 (edited) I hate to say this but" if it ain't broke don't fix it" So anyways don't worry your not the first person I know that's done this. If you look at the position of the shuttle driver it should look like this on the upstroke of the needlebar.Your machine has no adjustments,once you get the gears set properly so the shuttle driver is as in the pic it'll sew. Let me know if you have anymore questions. Bob Edited April 17, 2012 by sewmun Quote Share this post Link to post Share on other sites
Anne Bonnys Locker Report post Posted April 17, 2012 Not entirely sure I agree with that Bob. The amount of dust, rubbish and even sand that I have found in machines that I have torn down and cleaned is scary. The 29k15 in the shop at the moment had wasp nests all through it!!!! Don't know what condition they are usually in when you see them but I tend to be the place of last resort for a lot of guys who buy machines on ebay so maybe I am just seeing the worst of the worst. Also my customer base is mostly rural so wasps etc are often an issue for machines sitting in sheds for 30 years.
