Cutting 3" Hole in Plexi
chrisindfw:
What is the best way to cut a 3" hole in my plexi? I do not have a router.
Shoul I get a 3" hole bit or just take an exacto-knife and go around and around a few hundred times?
Thanks.
On a side note... If you had to choose a pc pinball game to use on your cabinet, which would you use?

If you do this, you will scratch your plexi repeatedly, as you can't possibly be perfect with each cut.
Someone here once posted about using a homemade jig for this, which I believe involved using a strip of wood (a paint-can stirrer, I believe) with a nail at one end and the other mounted to a hole-saw arbor on the other, 1.5 inches away. The arbor drilled into the center of the hole while the nail cut the circumference.

Visual Pinball with Visual PinMAME. Most FE's support it these days.

Use the hole cutting bit and run the drill in reverse. It'll take longer obviously, but it shouldn't crack the plexiglass (running it forwards will ANNIHILIATE it on the other hand)

Well.. Heres what I did.. Drilled a hole in one end of a strip of wood, poked a screw in the other end the proper distance away. Attached it in the middle to the plexi and round and round.. It took about 5 minutes and the screw point cut into the plexi and made an extremely clean 3" hole cut.
I couldnt have been happier.
Thanks

For the rest of you reading this consider using a hole saw in reverse @ your drill's highest speed
(and for the pilot hole also drill in reverse @ your drill's highest speed)
