Hello all
Sorry, long post. For the gist of it, please skip to the end part.
2 years ago, I was looking for a sewing machine for leather, not very expensive (this is a starting hobby for me), but knew little more than the brands usually mentioned in Google searches: Pfaff, Singer, Durkopp, Juki, etc. Iknew that I should try to get a walking foot machine, if possible, but the very few that I could find were VERY expensive. Being focused on thin leather pieces, I thought I could get by without a walking foot, provided I could sew 2 or 3 layers of soft, thin leather reliably.
I then found this Adler 268, twin-needle postbed machine, not too far away, for a price that I could afford. Went there, saw it stitching 3 layers of leather I had with me, and brought it home.
It was stitching well, but it was work-dirty, and some pieces had started rusting mildly. I cleaned it as best I could, afraid to disassemble it and upset the mechanisms, and used it like that for a while. I had, of course, problems with it, but they were of my own making, through ignorance. I even set it aside for a time, disgusted (more with myself than the machine) for not knowing what I was doing, and therefore being unable to do what I wanted. I stuck with hand sewing.
A few months back I got into a project that could really use long, regular stitches, so I put in the effort to learn what I needed, to be able to use the machine properly. I knew nothing, then, of sewing machines in general, and all the minutia that goes with them: needle sizes vs. thread sizes, hook timings, etc. It worked, mostly thanks to the members of this forum, and the many hours reading here, seeing videos and such, and I am now capable of doing most basic tasks needed to use the machine properly.
Amongst these references, I got the User's and Service Manuals for the Durkopp 268. The Service Manual refers to a large number of versions, but I am unable to identify exactly what version is mine.
Before you ask, the machine itself is no help: all the "Durkopp" labels are gone, the clutch motor is not original, and even the chrome plate that resides in the rear is blanked off (or has been replaced with a blank plate). I looked at it with a high-power magnifier glass, and there's not a trace of any markings. Usually, the version should be written there...but isn't.
So, there we have it: a badly painted, barely maintaned Durkopp Adler 268, postbed twin needle, 8 mm gauge, no walking foot, with no labels or indications of version. How can I find out what version (there are some 30 different versions in the Service Manual...) it is?
The Service Manual should help, but it is difficult, for me, to interpret the "Technical Data" table with "Features per version", since I don't know what many of the terms mean. I gather that the versions that have a number in the "Alternating Top Feed Stroke" line are the walking-foot versions, but even that is not certain for me.
So, any ideas about what I should do to find out? Any help is appreciated.
