I marked out the holes I'll need to drill, and also figured out what bits to use for the control knob expansion. I intended to do that drilling today, but a poor night's sleep and a full day of NFL playoff games here in the States kept me planted firmly on the sofa. Maybe if I have some free time tomorrow.
