Homebrew PCBs

Hi,

I'm interested in this way of building enclosures. Can you post some
pictures? An how do you bend the AL and make straight and nice looking
corners?

Thanks,

Joe

Sounds similar to the methods I use - 1/4"x1/4" Al along the "seams" and
drill and tap 6BA (6BA tapping is 2.3mm so probably similar to M2.5) to
screw the sheet to the square.

With larger with heavier contents enclosures use larger "square" and
screws (4BA - M3.5) or 1/2"x1/2"x1/8" Al angle.

Sometimes, of course, it is neccessary to have individual flat panels but
the joining method above works just as well for those.
