Glue strips of lumber around the edges of the your panel in the same manner
as the sidewall of the fuselage boat. Backup the backside of the panel at
each instrument with thin aluminum angle set vertically with the instrument
bolts through the instrument, plywood and aluminum angle. Make the aluminum
angle long enough to reach the upper and lower edge of the panel. Fasten
the ends of the aluminum angles at the edge of the panel. You could get
fancy and install nut plates in the aluminum angle to accept the instrument
screws. Depending on how you stack them, you could put two or more
instruments on the same pair of aluminum rails. When you are done, you
would have a 3 mm plywood panel that's braced with aluminum angle and hard
points at each instrument.

>I'm starting to build the instrument panel.
I plan to build the panel from 3mm (might
be 2.8, I'm not sure) plywood, and I need to know what thickness is required
to ensure the panel will be stiff enough.
I understand that it is firstly important to know WHAT will be installed.
Well, I'm very much in the steam-age regarding my instruments, so they are
heavier than the nice electronic gadgets one can buy.
Should I stick 2 plies together, or will one be enough?
Regards.
