Ed began by setting up the instrument layout on the computer (he loves this stuff).

Ed tried a few methods of starting the holes for the round instruments. He began with a 1" hole cutter.

Ultimately, he found drilling holes around the perimeter easiest.

The drill holes.

Lastly, use the dremel tool to smoothe the surfaces.

Then test the circle with an instrument to see if it need additional trimming.

For the multifunction "Square" hole, use the dremel cutter. Joanne held a piece of metal ruler as a guide.
