Danny,
There are several ways to accomplish the task. Water cutting is the
most desirable, and is extremely accurate. Laser will also work, though
not usually as nice a cut. Pre-sized hole punches do a very nice job,
but are ususally pretty expensive, so if you're are not planning to do
several panels, or rent the tools out, you might not want to go that
route. Then there thers's the old standby, the hole saw, used in a
drill press. A bit more work, but satisfactory results can be had, if
you're careful. If like some of us, you end up changing your panel 2 or
3 times, adding this and that, you might want to give this a try. My
panel is built from .063 aluminum and I changed it up several times,
before I was happy with it. The hole saw did just fine after I learned
the secret of getting smooth cuts. If you go this route, just take your
time and make sure to plan your panel precisely. Good luck.
