Mulesaw Report post Posted February 15, 2022 I bought an old Dürkopp 61-1 sewing machine last week. I was hoping for a different machine, but after taking the drive I decided to get it despite not being what I originally wanted. The needle bar and the guide bushings were so worn that needle bar could move 0.5 mm back and forth. I borrowed a reamer from a fiend and enlarged the bushings to 10 mm instead of 9.5 mm. I then made a new needle bar out of a piston rod from a pressurized gas cylinder like those that lift the back door of a car. The sewing machine has at some point been retrofitted with a clutch motor. And that works really well. My only problem now is that I need to find out what needle system the machine uses. There is only one needle in the machine. It says SIMANCO 25Y on it, but that doesn't mean a lot to me. The needle is approximately 60 mm long, and the diameter of the shank is a bit less than 2.5 mm. If anyone of you know what needle system that might be, it would be great. I am not emotionally attached to this machine, so if anyone would like it I'd be happy to let go to a new home.

Constabulary Report post Posted February 15, 2022 (edited) That basically it is a Adler Class 4 machine only Dürkopp labeled (Dürkoppp and Adler merged in 1990). Pre 1930 manufactured I think. Needle system is 328. Edited February 15, 2022 by Constabulary Quote Share this post Link to post Share on other sites
Mulesaw Report post Posted February 15, 2022 @ConstabularyThanks Folker, I had hoped that you knew the answer :-) I will try to google for an Adler class 4 to learn a bit more about the machine then. There is precious little information about Dürkopp machines on the Internet compared to e.g. Singer. Brgds Jonas Quote Share this post Link to post Share on other sites
