[HomeBrew] How to make a clean cut out for an LCD display?

[Ray LaRue]

Thanks to all who responded to my query.  I appreciate you taking the 
time to reply.

I have accomplished the task by using a cutting wheel on my Dremel tool 
and a sharp carpenters chisel at the corners.

I scribed the needed cut out with a combination square.  I then set the 
Dremel tool to the lowest speed and carefully cut along, but just short 
of the lines.  A few taps with the chisel made cutting the corners 
rather easy.  Then  I used a fine file to smooth any variations.  It's 
not machinist's perfect but it came out pretty good.  The escutcheon 
around the LCD draws most of my attention and makes the edges look better.

It's certainly good enough for a homebrew piece of test equipment for 
use on my bench.
