I was playing with a new cell phone camera and I have never posted a video to Youtube before. Posting was easy, but cell phone camera video quality sucks, I will try a different camera next time. But here it is anyway. It's just a simple interpolate hole with a 1/2" end mill with a little bit bigger hole on top of it. 6061 aluminum.
