Tap holes: subtract .002‖ from the desired radius and subtract 0.004‖ from the desired diameter for the
kerf. Tapping is a handy, strong, and quick way to fasten two pieces of laser-cut material together and
to enable later disassembly. Using our fast tapping tool or a tap in a portable drill, apply light pressure
on the tap in the tap hole, and the rotating tap will pull itself into the hole. When at the required depth,
quickly reverse the direction to back the tap out. If you wait too long, the heat generated by the tap
melts some of the plastic, which then cools and solidifies. This might seize the tap in the plastic and
break it when you try to remove the tap. For a Nyloc-like friction fit, don‘t tap all the way through, to
enable the inserted screw to thread itself through the small, untapped portion and provide a tight
friction fit that will withstand vibration.
Body holes: subtract .001‖ from the desired radius and subtract 0.002‖ from the desired diameter for
the kerf.
Clearance-fit holes: subtract .003‖ from the desired radius and subtract 0.006‖ from the desired
diameter for the kerf.

12. Quick Bevel Cut: To produce a beveled finish atop a normal cut:
a. Cut the part out normally. You might have to design small ―tags‖ to hold the part in place for
the next operation if the part will shift much after the initial cutout. Leave everything
untouched in the cutter after the cuts.
b. Get into FOCUS mode (push Z) and lower the floor by 1.0‖—10 pushes of the Floor down
button at 0.1‖ steps.
c. Make a copy of the vectors you want to bevel, change to a unique color, and exactly overlay
these atop your original object(s).
