(and for the pilot hole also drill in reverse @ your drill's highest speed)

I agree, but at the beginning of the thread he implied that he didn't have a 3" hole saw.  (I don't have one, either.)

I learned my lesson the hard way by trying to use the trackball mounting plate as a guide for my router...it ate right thru the metal.

So I made a template using a spade bit and a file.  Then I just placed the wood template in the new mounting plate and used a flush bit on my router to easily make the hole.

I also cut a 3" hole in some particle board first with a holesaw to use as a template.  Here's a picture of a 3" beveled cut I made in Lexan using a chamfer bit.  The bevel allows the Lexan to flow smoothly with the rim of the Happ TB.

easiest way hands down is to use a dremmel.  The cutting bit that comes with it is perfect for plexi glass.  I had a piece of Plegi-glass 6 feet by 4 feet, and I cut it down with the dremmel so easily it wasn't even funny.  The dremmel doesn't crack at all.  When cutting it makes little Plastic beebees from the plexiglass it melts/cuts.

Worked unbelievable.  I am going to drill some more holes in a day or two, I will just make a video of it and post it on the website.
