Knobs, how do they work?

[jk-fm]

I got all the piece from Mammoth to house my breadboarded booster, strated screwing them together didn't like the set of the knob, and ...

...yanked the axle right out of my 5k reverse log pot ...

The set screw isn't even in it, and it won't come off? Is it salvageable? What am I doing wrong?

What kind of pot are you using?

How do they work?  Just like you think, and like they're supposed to,

....unless there is a tolerance issue with either the inside of the knob or the pot shaft, or unless you have forced a knob onto a pot shaft that was expecting something a little different.

This is going to sound like a stupid question, but this wouldn't by any chance happen to be a knob with two set screws, would it?  Or perhaps a pot shaft that is plastic and subject to deformation if the set screw was adjusted to hard....even after said set screw was removed?

Solid metal shaft, one set screw. I managed to get it free, and it fits ok over a knurled 5K I have, I'll just number it backwards

Turning a 5K pot in reverse does not a reverse log pot make.......

Pried apart the reverse-log and superglued the shaft back on - everyone should take apart a potentiometer once! Now I'm trying to sand off any spurs inside of the knob.
