Dressmaker SWM-2000 zigzag does not work
Hi - this sewing machine is in very good condition and sews a good straight stitch. No zigzag, however. Zigzag, I believe, would be built in. I have 24 cams for it but those don't work either. It's an all metal machine, so a broken, cracked cam stack can't be the cause of this.... right?
I have oiled all the components of the zigzag mechanism, as far as I can tell, and nothing appears to be stuck. It seems to us that something is missing that activates the swing mechanism. A spring maybe?
We activated it manually, tried to compare what we see to several other zigzag machines but they are all different. We don't have another Dressmaker to take cues from.
I'm attaching some photos and hope that anyone can point to what might be missing here. There is a white small tab-like object screwed to the front edge of the machine that seems to have no purpose.... anyone know what it's for?
If nothing is missing, what might be the cause for the non-activation of the swing mechanism?
Thanks for looking!
