"I consider a shear essential unless you are not considering looks. Only
a few have the skill to saw and file with a professional look."
Although I have a shear, that may not be the perfect solution. In order to cut
thicker aluminum or steel, you need a 2,000 pound shear, which involves space.
And, often they are not able to do more than cut a flat edge the full length of
the material. If you are going to fold it, the shear may not be able to cut
all the shapes you need. However, both a table saw and a radial arm saw, with
a non-ferrous blade can make clean cuts (warning - secure things before you
cut). And, if you build edge guides, even a saber saw with a metal cutting
blade can make clean cuts.
