MOTM

Aircraft aluminum is really nothing special in the way of hardness.  It 
flexes better which is important for aircraft and it weld more cleanly than 
lower grades of alu.

I happened to have a 15/16 greenlee punch hanging around and a old MOTM 
panel.  The punch went through fairly easily using  a 8" adjustable 
wrench.  Put some Tap-Free or other cutting oil on and it makes a nice 
clean hole.  WD-40 would work as well.
