Brief Description: Cutouts for breakers, EFIS, radios, and switches
Used modified wood paddle bit, fly cutter, and die grinder with thin cut off wheel to make holes in instrument panel. I uploaded 2 videos to youtube showing how I made perfect round hoes with modified wood paddle bit. Much better control than with a step drill having the panel clamped down with wood backing to keep the paddle bit centered. Less expensive than step drills too.
