John,

Go to

http://www.craggyaero.com/ultimate.htm

Download the 2.25" and 3.25 Instrument hole templates at the bottom of
the page and follow the directions.

A 2.25" hole saw will work fine mark the center hole as in the
directions and us small pilot drills for starter holes then the 2.25"
hole saw then the instrument screw holes.

Make sure and use a punch to get the starter holes exact.
