Step 2 Drill It Out

Carefully mark and drill the holes for the switch and jack. I use drill bits with sharp points at the tip for metal because they tend not to slide around before they dig in. Keep the holes low in the case to allow room for the lid to close all the way. A later picture will illustrate this. If your switch is bigger than mine or you accidentally drill a hole too high, just use a circular file or perhaps a dremel tool and file the lid a bit until it closes. Also, it's a good idea to drill your holes just a bit smaller than they need to be and file them the rest of the way for precision. At least, this works well for me. Different materials call for different techniques as do different people. Do what works best for you.
