I have a 1940s era Hamilton Beach malt mixer and would like to replace the power cord. In order to do so I need to remove the metal base cover.
The base cover is held in place by screws that are recessed into the rubber feet and the screws are badly rusted and/or corroded. Only the screw heads are exposes (and recessed).
I've used penetrating oil years ago on bolts with nuts where the threads were at least partially accessible, but am unsure how to approach the current problem.
Ideas?
TIA
