Today I countersunk one of the longerones, which took an hour or so. First I set up my single flute countersink, and dialed it in on the drill press. With that done, I hooked up my air drill and countersunk one of parts.
I was really happy with how it worked out. The single flute is superior, and requires a lot less pressure to cut. The consistency of my holes was much better than with the 3-flute sink, and it felt easier to use for some reason.
After a lot of drilling, it was midnight and the compressor had been running almost continuously. I decided to tackle the other one tomorrow
