Anyone here have any experience with SAFELY (meaning not to screw up vintage knobs that are rare) enlarging the hole in the knob to fit over a larger shaft?
The original plastic Fender F knobs are too small a hole to fit on the new electronics.
I want to retrofit them and use them, but sure don’t want to ruin them as they are super rare and hard to get.
I don’t have a drill press (maybe an excuse to buy one?).
I do have a dremel and a vice.
I often find working with the dremel in the vice and holding the part yields better results. I have a carving bit and two different size grinding/sharpening bits, both cylindrical that might do the trick if I go slow and steady, but wondering if anyone has better ideas?
I am ok with going a little too big, can always tape the pot shafts if needed for a friction fit.
I have some cheap ‘practice’ knobs to try on btw.
