More Dome Cuts

Tonight I cut out the two button holes with a tapered drill bit, and the rectangular holes where the LEDs show through using a Dremel with a cutoff wheel.

I'm telling you, that tapered bit is awesome! I only wish they made them in HP diameter size.

One more hole to go, the "perfect circle" that I'm stalling on. I have a carbide burr bit on order from McMaster Carr for smoothing down the rough edges, and I want to test it out on existing holes before I tackle that last hole. Mike Senna said he used a bottle neck with sand paper wrapped around it to finish his off, I'm sure I'll do the same.
