When I made mine I first made pilot markings in the wood and then drilled out all the holes in the wood. Next I screwed the lexan to the wood and then removed the mandrel from the bit and drilled through the back of the lexan using the holes in the wood to hold the bit in place. Go slow or else you'll need to use an exacto to clean up the top edges of the holes. To make my artwork holes match, I placed the artwork on a glass table, taped it down and then lined up the lexan on top and taped that down. Next I used an exacto knife to careful remove the holes in the artwork. In the end, all holes matched and all hardware fit perfectly. |

Cut the plexi like hot butter for me. I've also found that hole-saws actually work quite well in making holes in plexi without chipping and cracking. This is what they look like, BTW: http://www.m3post.com/forums/attachment.php?attachmentid=806840&stc=1&d=1358032071 I was surprised at how well it worked, actually, because it seems like it would be too crude to work. I think it works because the friction heats up the plexi and softens it, making it just as much a "melt" as a "cut". |

Slower is better. If you are drilling plexi by clamping it to your Control Panel (With Art Work), take you time as the plexi can heat up and create little plastic balls that can wedge between your plexi and Control Panel, thus scratching the nice art work. Sandwiching the plexi between the Control Panel and wood stock will help prevent chip out. |

Any suggestions on how to best clean the little plastic bits that the router creates? I find that even with multiple cleanings the plexi seems to pick up these little bits like a magnet. They seem to be charged and stick to everything. |
