I have some aftermarket control knobs, one had a stuck screw and I couldn't get it out. Ended up mangling the screw a few years ago and likely the hole where it went in. Was going to just toss them, but what the heck. These are those heavy knurled knobs and was thinking of drilling the bad one out, but not sure if it would require re-thread epoxy or how to go about it the right way. Not caring about how nice it will look, just want a functional screw to tighten it to the solid pot shaft. I would appreciate any feedback, thanks!
