You should wait until your CPO returns from Mamemarquees.
When you get it, lightly tape it down for a bit and use it to drill 1/4" pilot holes in the exact places that you will need for the final holes you need to drill. If you try to cut first and apply later... it usually meets with mixed results.
For instance.. if you are drilling button holes... you don't need a template, just the position and a correctly sized bit... same with the joysticks. You drill the pilot holes, then come back later and use the 1 1/8" bit, using the pilot holes for centering. If you are drilling a trackball, use the CP to drill a pilot hole in the direct center... then print a template that shows the where the center of the trackball will be, and overlay that over the pilot hole.
