Many thanks Tigweldor! Got it. In case someone else comes across this thread, the key was loosening the locking collar on the inside of the locking wingnut. With patience and continued lubrication/cleaning, this allowed me to back the thumbscrew out completely. Hardly any visible material in threads, however a little cleaning after removal with isopropyl alcohol made a world of difference, even before oiling. Thanks for the references above as well - much appreciated. Having done a pretty thorough cleaning at this point, I am really pleased with the machine and the excellent condition it is in. I am really looking forward to using it. Thanks again, Daniel

Hi Folks: I just bought a 1972 Adler model 67 sewing machine in very good condition. It has been sitting for the last 15-20 years. The thumb screw and wing nut for stitch length adjustment are really tight and barely move. I can get a little movement with initial lubrication, but am reluctant to force anything before I know which way to go. My understanding is when the wing nut is up, I should be able to turn the thumb screw in and out to change stitch length, then turn the wing nut to the right to lock it in place. Am I correct? Any suggestions for proceeding to loosen this setting? This is the first walking foot machine I have owned so this is new to me. Thanks for any insights and suggestions. Best, Daniel

Hi folks: I know the Singer 20U is undersized for leather work. I am trying to set up a binder and need some help. The machine has the usual two holes in the bed for attaching binders. However, the usual knurled screws that some with binders are not the right size. They fit my other machines (e.g. Juki) but not my singer 20U. Does anyone know what screw/thread size these holes are tapped for? Many thanks for any help, Daniel
