| Cut Holes in Acrylic Overlay |

Hey guys- Am getting ready to cut holes in the CP. I bought some high impact acrylic at Lowes tonight ($14 OUCH!). I also bought a spade bit for the buttons and a regular hole saw for the tbs. Question- I'm worried about the spade bit and hole saw splitting/chipping/breaking the acrylic overlay. It says it's high impact, but it's only 0.80" thick, and I've easily split this stuff before drilling holes. I know I can tape the holes with Duct Tape and cut the holes slow, but, I'm still worried about it. Mainly worried about the Spade bit doing it- should I go back and get the hole saw instead of the spade bit? Or, will the spade bit be ok? Any insights? Thanks! D |

Make sure the acrylic is sercure and there's no chatter when you drill. Also, don't push hard when drilling. |

The hole saw works much better than a spade bit. The spade has a higher chance of cracking the acrylic, and with a hole saw you get a somewhat cleaner cut. |

Hmmm- that's what I was afraid of. The hole saw was more expensive, but, cheaper than buying another piece of acrylic, that's for sure! Also- I will tape the areas before I drill, but, should I also sandwich the plastic between boards? Run the drill in reverse as mentioned in other posts? Or is some of this not needed? Thanks for the input... D |

Well, I sandwiched mine between boards and I used C clamps so that the acrylic wouldn't move around so much I didn't bother running the drill in reverse. You might still get a gunky build-up of melted acrylic due to the heat caused by the friction but it's easy to clean off and much better than cracking it. By the way, some places like Tap Plastics: http://www.tapplastics.com sell acrylic for a lot cheaper. I bought mine for less than $9. |
