Arrggh - I think my walking foot is done for. Somehow, the upper hook part, which hooks onto the screw which holds my needle in place, is somehow loosening the screw, causing my needle to come out while I am sewing. Sometimes I can put it back in, without it even coming unthreaded, but sometimes it snaps. Since I know this, I stop every few inches, check the screw to see if it needs tightening, which it never does. Then all of a sudden, it just happens.
Has this ever happened to any of you? The foot is a number of years old (maybe I bought it 7 or 8 years ago?) but I don't use it all the time.
Other than this issue, the foot functions fine - guides my sandwich evenly and all - but I am getting frustrated.
Any tips or advice?
Thanks all!
