I just drilled two half-inch holes in the switchband of my Formula 200. I used a forstner bit. It had to get through about 1/4" of FG and the epoxy between the two layers.
The inside of the coupler flaked. I don't know if that's the right term.
Anyway, for my static ports (I'm going with four 3/8" holes), I need them to be clean and not flake. I will be buying a new bit for this. So:

Anyway, for my static ports (I'm going with four 3/8" holes), I need them to be clean and not flake. I will be buying a new bit for this. So:
- Should I still be using a forstner bit?
- Will a brand new one do better (cut cleaner)?
- Should I put a layer of duct tape on the inside of the coupler?
- Any other ideas to prevent flaking?
