I just used a regular cut off wheel to cut plexi.. though it cuts it very quickly, so you gotta be quickly... and it does make somewhat of a mess of the edge of the plastic. So I suggest cuttin ga little bigger than necessary, and use a sanding bit to bring it down to the size you want. The sanding drum will clean up the edge a bit.

yup, thats the best way, you can also get a stanley knife and keep grinding it trough the same cut untill you reach helf depth, and then break it along a table edge or something (only good for straight edges, and hard long work)

That should still work... just make sort of a "blocky" circle around what you need and sand it down, the sanding can handle the curve if you use a smaller drum.... or you could just find the bit 16-bit was talking about (ha ha... bit 16-bit wooo anyways....). Either way it should work.DCFan2004 wrote:only problem is i have to cut a round edge so how effective would the cutting wheel be?

yeah i've found that out myself. What I did was cut two dime size holes on the front side of the system next to where the controller port is. My intention is to fill the two holes with pieces of plexi and mount LEDs behind the windows. I think my biggest mistake with all of this is is that i bought the top end plexi at Home Depot so its a bit stronger than the usual piece.

When I cut plastic, I use a big motor, the I beleive was out of a hair drier. The friction from the shaft heats the plastic fast and just kind of burns off. It leaves a perfect edge and is very controlable. You may want to look into it.
I beleive it's the same type as the "johnson" motors.

There are special blades made just for cutting plexiglass. They look like a blunt razor blade. You have to score the plexiglass sheet several times with it, until you make a groove. Then, you "snap" off both parts, and you get your cut. It's a bit like cutting glass.
But, for round cuts, the best way to do it would be with a manual jigsaw. You draw you edge on the plexi sheet, and you follow it with the jigsaw. It works great.
Motor tools will just cause a lot of expensive mistakes. A manual jigsaw has a huge degree of control. Once you get your cut, you can sand down the edges, and polish them with car wax, to get a "laser-cut" look. It really works. I once made a subwoofer grille with this method, and people tought I had it cut with a laser.

US Plastic Corp has all KINDS of awesome plastic/vinyl/whatever polymer products. They've got different styles and grades of totally clear (see-through) CD cases, which I've used to replace broken Dreamcast cases. They even have precut acrylic circles and stuff, and they go down to 1/16th inch for some of their sheets.
