actually all it is is a router bit. A regular 2 inch cut 1/2 inch diameter, 1/2 inch shank straight bit, maybe 10 usd. Not exactly expensive. Ill just get another.
Pete that is a freaking huge mill, and I thought the one I was using was rather large. It can cut 4'x12'x5" as a 3 axis, more then enough for a simple guitar.

edit: The bit ended up coming out to $18 shipped only cuz I dont have the time right now to drive to home depot to see if they have one
