Gyros will last a lot longer if their itty bitty bearings are protected
from vibration,---one way is to make a separate panel with all the gyros
in it, and suspend this panel from the rest of the Inst. panel.
Make provision to add more vibration mounts---sometimes you can get a
resonant vibration at cruise RPM


Your post's wording was a little unclear to me. Are you saying to mount the
gyros in their own shock mountings, then add even more vibration mounts, or
were you just re-stating that the initial addition of vibration mounts is a
good thing?

OK--Fer instance--lets mount 2 instruments in a 4" X 8" pc of whatever
you like---then put four of the little Lord rubber-baby-buggy-bumpers ,
one in each corner of the panel---if it vibrates badly at cruise RPM,
then add one or two more--this will change the resonant frequency and
move it somewhere else in the RPM band--maybe even above Red-Line.
