any one know how to fix this knob its very stiff.
When things stick I have often used an oily spray. When stuck without any proper one. I have used normal fly spray. Don t know if it would fix this or not.I had an old bernina it was great. Actually I used to sew prawing nets for a living on it. Very reliable machine.
WD40 is the stuff invented for this - but you should follow it with a drop or two of very light oil.
