I wonder if folk could tell me how they usually go about mounting potentiometers so that the things are relatively hardy (can take a bit of punishment without moving or rotating) and the gap between the level of the dial exit and the bottom of the actual knob isn't too much.
I have this potentiometer, I have it doing what I want it to do in my circuit with a PIC, and I'm now wondering about mounting it. Obviously it has a nut and washer, I am assuming they go on the outside of the mounting surface. However, it also has a metal protrusion which I am assuming is to go in some kind of cut-out in the mounting surface to help stop the potentiometer itself rotating, instead of just the dial.

At the moment, I have drill bits, but I don't have a tool for cutting out a square hole for this, I guess it could be any round hole and some glue at the end of the day. Same old story, this new hobby, a black hole for money; I keep finding new bits I 'need'...
Is this the right way to go about it? I push the potentiometer's dial through a hole I've made, I create a separate 'guide' hole or recess for this metal protrusion to go into, I use the nut and washer to lock the potentiometer down in the outside, then I put the knob onto the dial... even then I'm thinking there'll be quite a big gap between the mounting surface and the bottom of the rubber knob.
I'm not going about it the wrong way, am I?
