Never would have thought alcohol would work for hot glue? I hot glued a knob to a cheap encoder module that I was trying to use a couple years back since the knob was surplus aluminum but no set screws. When I was done I gently heated the knob till glue was soft enough to wiggle off, the knob is worth more than encoder.
I¡¯ll have to try the alcohol next time, I¡¯ve tried acetone before not much luck. Thanks for the idea.

I have not used this method but people use alcohol water mixtures to remove hot glue. But it appears that not all hot glue is the same material. It is not an immediate softening. It does not mix safely with the heat gun technique.
I have used a strip of brass shim stock inside a knob and a slice of aluminum can would not be beyond me.

Use a heat gun to soften the glue, should come off then.

However, even the 3mm knob I have seems wobbly...
it may not actually be metric, but a 1/8" knob.
Again, I'm still waiting for my uBITXs to show up. The
shaft diameter on the knob I picked up for my BITX40 was
too large even though it was the size specified. I wish
I had thought about heat-shrink back then. I ended up
putting a squirt of hot-melt glue in the knob before
putting it on the volume control shaft. It will be
interesting if I ever have to remove it!
