Subject: | Mounting Antennas On Bottom Fuselage Skin... |
Fellow Builders,
I'm getting ready to mount the COM (Commant bent whips) and Transponder (Commant
shark fin) antennas on the bottom of the RV-8. I plan to mount them to the
bottom fuselage skin right behind the aileron torque tubes. I think this is something
like .040" skin and its pretty rigid, but what are people's thoughts
on adding a skin doubler, perhaps a .032 piece something like 6"x8"? I'd rather
not, but on the other hand, I don't want to have the skin end up deformed over
time.
Thanks in advance.

I believe the skin is 0.032" not 0.040".
Recommend using a 0.032' doubler. 6"x8" is larger than needed however.
Consider something that extends and inch or two beyond the antenna mounting
screws. A simple install is a little bit of pro-seal between the doubler
and the skin, and then the antenna hardware through both the skin and the
doubler. Don't be concerned that you do not have perfect metal to metal
connection. The antenna needs an RF ground, not a DC ground. As long as it
is mounted on the skin you are ok, even if you have primer/paint on the
skin.
Put some spacing between the two antennas, perhaps a couple of feet.

Subject: | Button Labeling For Infinity Stick Grips... |
Dear Listers,
I've been pondering for a while how to "label" the various button functions of
the Infinity stick grips I have wired up in the front and back of the RV-8. I
spent some time today with the 'ol CAD program making a caricature drawing of
the Infinity stick grip and buttons and adding some labeling. My plan is to
silk screen the attached layout right to the instrument panel in the front, and
to a small metal piece for the back. The cockpit and instrument panel will
be black, so the diagram should pop nicely on that background.
Just thought I'd pass on my efforts.

In my crude survey of other builders, I discovered that 2/3 or more of builders
do put a doubler plate on the inside of the bottom skin for at least the comm
antenna. As you suggested, about a 6 x 8 inch piece of .032 material. But I
suspect that a 6 x 6 piece would work, if that is what you happen to have laying
around.
I have seen that doubler riveted with both countersunk and universal head rivets.

if you bend up 1/4 in on each side, the stiffener will be more stiff .. j
