Wolfleather

I have exactly the same problem as in the second video. I've been bothered by this monster for two months. Without the material it's not a problem and the loop picks up nicely, but when I put the material in the loop just gets too small. Aside from that it works beautifully, overall for being one of the first ones made (I have number 5347) so it's basically in perfect condition in terms of worn. I'm trying to hunt for information where I can and I'm still short on it. That's what I get for not buying a Singer 😄

Hello, I have a Durkopp cl 18 at home, I found this manual a while ago which is great but I couldn't find it complete anywhere on the web. Does anyone have it complete or any contact to the author? And now a problem that I'm just not able to solve. My top thread is making an awfully small eyelet, so the hook is unable to catch it. I've tried different threads and needles (I still have the original needles). But no matter what I do the loop is just too small. I have a nagging suspicion that I did something wrong in the renovation. Translated with DeepL.com (free version) copie.pdf
