Drill 2 holes in it, one at each end of the rectangle. Then use a dremel with a fiberglass reinforced cut off disk to cut out the rectangle in between the 2 holes.

no need to drill holes if your using a cutoff wheel

dremel also has a titanium cutting bit.. it looks like a small bit for a mill..cost about $10 but works great.. i forget the actual name of it

Yes you do, if your cutting a long skinny rectangle with a large cut off wheel. You can make the long horizontal cuts easily with a cutoff wheel, but how do you make the short vertical cuts?

It makes it WAY easier if you put a hole in at both ends, and it'll turn out cleaner too.

Somehow I think it involes a 4 1/2" grinder and cutoff wheel.
