actually. :-} I imagine the inside of one of those is somewhat more
complicated than a flat metal bracket.

How strong is the metal? And how heavy? I mean, I guess it varies by
which particular alloy you use... Presumably somebody has already
tabulated this data? I imagine for a sufficiently small part, you can't
physically apply enough torque to it to actually bend it. (In normal
circumstances, at least.) I guess that's why small twigs sometimes seem
"stronger" than large branches...

Hmm. And now I'm wondering... how do you manufacture the tool you use to
manufacture the thing you actually wanted to make in the first place? :-D
