I donno about plexi.... but I'm planning to drill a 2+ inch hole for my trackball on lexan... I'm planning to use a plunge router.... there is a circle drilling plate that can be used to drill circles.... that plate costed me $30 (S&H included) but can drill perfect circles from like 2 in up to like 7 in in diameter.... |

He's putting his trackball plate on top, though. Doesn't need to be a perfect circle. Just needs to fit his trackball. As for cutting holes, I don't know why a hole saw wouldn't work for lexan. Only cuts one size, but it's much less expensive. Would be usefull if you don't plan on cutting other sizes. |

Drilling Holes can be done in both. I have done it with both a Spade Bit and a hole saw. I wouldn't waste your nice Fornster bits on it, you're after all going all the way through. Spades suck in the fashion that their is really only two points cutting so it has a higher probablity of catching and snapping the material. Holes saws are nicer IMO. |

I cut my Lexan overlay with my Dremel rotary tool and one of those discs that came with it. The Lexan was only about 2 or 3 millimeters thick, though. It would not have worked very well on anything much thicker. I drilled in reverse for the holes as has been mentioned here many times. |
| AlanS17:
For lexan, I recommend a hole saw, drill forward, and don't apply too much pressure. Pressure increases the friction and temperature. You want to cut through - not melt through - if you can. Melting can cause the hole to actually shift or cause excess material build-up around the hole. |
