I've used a hairdryer on many stuck parts--to loosen the screw on the faceplate of a Model 12 with about 140 years of oil gunked around it; the ZZ mechanisms of machines; a Viking that won't make it's decorative stitches, etc. A necessary item for the tool box!!

( refering to the knob you loosen to wind a bobbin) Any ideas anyone ?
