Cutting trackball hole in plexiglass (revisited)
Pixelhugger:
If you have a router you can chamfer or bullnose it. You don't need a dremel to polish it. If you have a drill... which you must... you can get a cloth polishing wheel for that and use it to polish.

I also used a router to round over the edges on my plexi, but I flame polished mine. Basically it is round over edges, sand with 180 then 220 then 400, then with a VERY light touch and a few minutes of patience, melt the edge with a small butane torch. You get to magically watch the stuff go from frosted to clear in seconds 8)
WARNING/DISCLAIMER! Practice on scrap first. This is an aquired taste, and takes some getting used to. If too much heat is added, the plexi will bubble and distort. On mine I just pass the flame quickly over the edge repeatedly, sneaking up on it so to speak, until it just starts to kick over. If you over-do it all is lost.
I'll try to get some pics and post later.
EDIT: pic added... ignore the white fuzz at the inside of the opening, its just rough edges from a temp cpo. this polished opening took approximately 15 seconds to flame :)

Just gotta find a polishing cloth wheel for plastic now! Will have a mooch around

May not need to mooch much. Should be around $7 at the local hardware store.
