Jim and all the main thing is that the tools used for scoring the aluminum
needs to be sharp and hard. I have used old files and they seem to outlast
any blades I have used in a utility knife.

I wonder if the handheld scoring tools sold at home centers for use on
plastic sheet would work on aluminum? I think I have one somewhere; if I
find it I'll give it a try.

Hey Jimmy ! That should work. I'll give that a try. Many years ago I
received free samples of thin flat brass sheet that were shaped and
scored
so the flat sheets could be bent to form a 5 sided box that could be
soldered on PCB's as RF shielding enclosures.

Jim, if you have a brake you can measure the size of the pieces you
need,
then mark your pieces with a fine tipped Sharpie. You can then use a
good
straight edge and score the pieces with a good utility knife or a
sharpened
file. Score the pieces 3 or 4 times using quite a bit of pressure.
Clamp
the aluminum in the brake then bend the metal back and forth 3 or 4
times
and it will normally snap off fairly smooth.
I wouldn't use that method all the
time but in a pinch it will work.

Is there a practical way to score thin aluminum sheet so it can
simply
be
bent and broken away?

it
comes to thin gauge Al. Mount the blade backwards.
