Took a small piece of wood. About 1x4" or so.. Drilled a hole at one end, and screwed a screw all the way through the wood so the point is poking out 1 1/2" from the hole.

Drill your center hole for the trackball.

Put a bolt through the hole in the plexi and throught the wood..

Rotate the wood. It slowly cuts a very clean hole. It takes about 5 minutes of turning. About half way through i moved it to the other side of the plexi. I make the hole slightly smaller and then made it bigger with a dremmel so I have a tight fitting.

Just my ghetto way of doing it without getting a router and such.

Can't use the trackball mounting plate as a guide for the flush trimb it eh? That's really a bummer... I hate when I think I have something figured out in my mind then find out it doesn't work that way... seems to happen all the time in this hobby LOL  ;D
pointdablame:
why wouldn't you be able to use the trackball plate as a guide? It would serve teh same purpose as a piece of wood with a 3" hole in it.  That is what I plan to do also.
ThePaul:
I've read a few posts where people say the tb mounting plate is too thing to use as a guide.
patrickl:
What I wonder most is the 3" size of the hole. I understand this was mentioned before, but I find it so hard to understand that could be the right sized hole for a 3" trackball.

Maybe off-topic, but on the mountingplate trimming issue; even if you can't use the mountingplate directly for trimming the plexi, you should still be able to use it to trim a hole in wood to use as a template.
