Cut Holes in Acrylic Overlay
Xiaou2:
actually, a spade bit will make a smoother hole.

wow- this is great advice! Maybe I'll go get that hole saw since I don't have a press or guide. I'll let you guys know when it's done. I still don't have the graphics done yet- not even started. In fact, I'm lost for ideas. I might just cheese out and take a pre-made overlay- lol... and to think I got my Master's Degree in Computer Graphics! LOL!!! Oh well, time is money, and this is just a fun little project, so design isn't overly important.
Thanks for all the help guys!

I sandwiched mine between the control panel and a bit of scrap plywood. Freehand drill using a spade bit and it worked perfectly. No cracking whatsoever. If you have a steady hand you really dont need a drill press.
Test on a bit of scrap to make sure.

Hi,
I've used a spade bit also ... I think that the holes get to be much more smother then if you use hole saw ...
How I did it:
- Drill the acrylic attached to a piece of wood, preferable with the same size of the CP / plexi (no need to sandwish it)
- Do not remove the protective cover ...
- Use high speed (2000 rpm) and drill very very slowly ... this rotation speed will heat a little bit the acrylic and then it comes out as little strips of soft rubber ... the surroundind of the holes look perfectly smooth ...
For the trackball, I used a dremel with the wall cutter bit ...
