This machine came with one decorative cam. It does not have the Zig Zag cam. I looked for one but did not find one. Darn. I found a deco cam that makes that "box stitch" If you lengthen the stitch it will zz but in an odd sort of alternating way. It could work for a zz substitute. I don't know how hard it is to come by these zz cams.
It sewed through this leather without a complaint. BUT I would not want to do it day in and day out. I don't think the motor would last. It is one of those naked internal motors and I don't know how easy THEY are to come by, either. I tired to access the brushes on it but couldn't . From what I saw of the commutator, it looked clean.
I honestly like the stitch these 328s make. True it sounds like a tractor and it is a cheapo machine. None the less, it makes a lovely stitch and will last a long time. Longer than the modern plastic machines made now.
I am posting this on the website. It's for sale. I have to move some machines out.
