Help with Singer 128-23
I just adopted a Singer 128-23 vibrating shuttle electric machine. Birthdate April 1952. My problem is that it won't make stitches. Cleaned it up, changed the needle, threaded, wound new thread on bobbin. Needle thread seems to have good tension and shuttle thread runs out of shuttle good. It picks up the shuttle thread good, but when I try to sew, it does not make stitches. I am not very knowedgable about vibrating shuttles, even though I have 3 now and I don't know how they form stiches to evaluate what is not happening. Any tips would be MOST appreciated. Thanks in advance. Maggie
