I have a 1941 singer 99 that I cleaned up last summer. Love it. However, it has a few "issues" that I thought someone could help me with. The slide plate to access the bobbin is really stiff, even after cleaning, and I find myself using a screwdriver to get it open, but there must be a better way of making these slide a bit easier?
I'm also having trouble getting the needle action to disengage after releasing the knob on the handwheel when I want to wind a bobbin. I've flipped over the appropriate washer, all is clean inside, etc. Does anyone have more detailed advice?
My machine came with the older non-hinged straight stitch foot, and seems to shift out of tension adjustment when I used a hinged straight stitch or zipper foot. Is this common with the older machines?
