As for the instrument panel cutouts, I am firmly in the holesaw camp--the carbide grit blades are great for that. I get a fair bit of stuff waterjet and laser cut, but only where it is the most cost- or time-effective method. For a round cutout and four screw holes, a good holesaw plus a template from the Schreder library makes it a five-minute job.

Thanks, Bob K.

I laser cut an acrylic template off an AutoCAD file that I'd created and used a template router bit to make the panel. All the holes were good to around two thousandths of an inch - which is what I needed because everything was pretty tight.
