drilling/cutting holes in plexi?
<< < (3/5) > >>
ChicagoDave:
I used the sandwich method (mdf - lexan - scrap mdf) and a 1 1/8" Forstner Bit to cut the holes for the buttons.  To cut the hole in the lexan for the trackball, I used a flush trim bit and a router.

Not applicable to button holes...

It's what I did. Less worry about chipping and cracking.

The teeth are pretty far apart so it would be pretty rough on the plexi.  If you try that method, have the drill in reverse and melt the plexi instead. 

Try a test piece first!

I had to use a hole saw for my trackball hole (didn't have access to a router/flush trim bit at the time).  It worked OK, but it left a very rough cut (lots of jagged melted plastic).  I just had to sand it smooth and then it looked fine.  Of course, make sure you are using the center guide drill bit with the hole saw (or whatever it's called).
