Step 24: Drill the Knobs

Picture of Drill the Knobs
Most dimmer knobs are designed not to be interoperable. In other words, they all have annoying plastic notches in them which prevent them from being put on a generic potentiometer.

To fix this, drill out the mounting holes of the knobs using a 1/4" drill bit. Be careful not to drill all the way through the knob. The goal here is just to hollow out the mounting hole.
