Quick update: My dad decided to let me use his tools today. Unfortunately, I wasn't able to get there until 3:00, and it got dark about 5:30, so little got done apart from making the rig for the saw. Anyway, here are pictures:
Here's the rig we came up with. It's really simple, but the cuts are perfect.
Unfortunately, the table saw did not work out, so this was our only option. The plastic would travel up the blade of the table saw and come out crooked.
The piece we made was the LCD bezel. The outer edges have 45 degree beveling, but the inner edges don't. I intend to sand them down by hand.
How we cut the inner edge:
It came out with some small pieces left in each corner, so I hacksawed them in half.
My dad is off work next Thursday, so we should have time to finish. Until then, I'm going to be working on the metal frame.
EDIT: Got some sanding done.
Sorry for blurry pic. My camera's autofocus was being ornery and I don't have enough hands to do manual while holding the bezel up.
