Hello, Can anyone tell me the purpose of the head revolving bush friction spring on a Singer 29K15? After purchasing a new revolving bush, the friction spring doesn't fit on properly next to it any more. Probably because the revolving bush is for a 29K71... Anyhow, everything seems to work fine without it, though I may be mistaken. I am still not getting 5 stitches to the inch, but I believe this to be a separate issue. Thanks! Ana Kim

Thanks so much Wizcrafts and Anne Bonny's Locker. I bought a new bell crank lever through a company in England, but I was unaware of this problem with the gadget on the spring at the back. Mine does indeed slide around, as the threads on the screw are nearly nonexistent, thus leaving it not doing its job well. I finally found that I was missing the bushing that fits around the needle bar, that holds the heavy piston in place. It was falling down leaving its entire weight resting on the bell crank and obviously preventing that from moving correctly. I believe I still have numerous problems to sort out and may try plating the bell crank lever as I'm not sure I trust even the "new" one. Someone suggested to me that it would be a copy several generations removed from the original part. Anyways, thanks so much again for your expert advice!

So if I have zero stitch length (the timing of the horizontal and vertical foot movements are nonsensical), then I need to fix or replace the bell crank lever and the ring slide bar? As I understand from various of the above posts, these two parts (the ring and the bit that moves around inside it) need to be tight enough or the foot doesn't move properly. Can somebody with mechanical understanding confirm this? I am unclear on whether these are the only two parts I'd need to order to make my machine work.

Hello: I am new here and yesterday I stumbled upon Wizcraft's advice about 29k4s and the stitch length regulator problem. I am trying to get a 29k15 working and had been breaking my head, tearing it apart trying to re-adjust whatever I could to get the foot to go up and down and back and forward together. Thank you so much for this information. I have a further question, that is, what parts would you recommend replacing to solve this problem? You mention stitch regulator (little bit that clamps around the foot bar), but I assume that it would be important to replace what is called "feed motion bell crank lever" in the manuals, and probably the "foot bar" that sits between the two parts of the crank lever. It looks like these two parts are responsible for the fwd backward motion. I could imagine that there are other parts that may need to be replaced too. Further question: you mention welding onto the "regulator". I don't understand. In a list of parts with associated pictures that I found on hensewfiles.com, it seems the regulator is just the tiny thing that clamps around the bar, and I don't see how fixing or replacing that would solve the problem, because it can already be clamped tightly around the parts that move back and forth (but please explain if I am wrong, because I am only a beginner). Please pardon my many questions and I am really grateful for any advice!! Ana Kim
