Summary
It\'s too easy to think that a laser cutter has an infinitely thin beam. It doesn\'t. Depending on the material, speed, power, we\'ve found an \"effective tool diameter\" of 0.002 - 0.008 inches.
This hole gauge cuts and labels 100 holes, from 0.050\" to 0.149\" in a 3 inch square pattern. When cut into the material you are using it can tell you EXACTLY how large to make body or clearance sizes for various screws and rods, and how large to make tap holes for self tapping.
The sizes will cover hardware from 0-80 to 6-32.

Instructions
Use the CDR file to drive an Epilog or similar laser cutter. Use color mapping to cut through your material on black, and to vector etch the lettering on red. Typical settings for 1/4\" plexiglass are:
- black: speed 10, power 100, , pulses 5000 Hz.
- red: speed 100, power 50, pulses 5000 Hz.
YMMV.
