I have done steps 1,2 and 8 with the wing open, but there should be no
problems doing it with the wing closed. I have not done the other steps
yet.
Step 1 -- Use a 5-inch diameter hole saw and cut a hole in the bottom of
the wing adjacent to where you want the AoA pressure ports. Make sure you
are
not cutting into a fuel tank. (Duh!) I put mine in the dry bay outboard of
the ailerons. I have a header tank.
Step 2 -- Prep (decore) the upper and lower inner surfaces to accept the
phenolic tube. Note that you may need to sand down one end of the phenolic
tubes to get them to lay flush against the inner skin.
Step 3 -- Install the hose barbs onto the phenolic tubes.
Step 4 -- Flox the tubes in place.
Step 5 -- Paint the outside of the tubes with epoxy to prevent air leaks.
Step 6 -- Drill small holes in skin as directed.
Step 7 -- Run tubes out to wingtip and then inboard via the PVC conduits.
Step 8 -- Make access panel from piece of skin you cut out. (Make flange
around gaping hole, make holes in access panel, fill in holes with flox,
drill
holes thru to flange, attach nutplates to flange, countersink holes in
access
panel.)
It should be pretty easy, even if the wing is closed.

[My only suggestion is regarding step #6... don't drill the pressure port holes until after the airplane is painted (or primed if going to be flown in primer). That way you're not fighting with a paper clip or some other indicator of where the holes are in an attempt to keep from closing them during the finishing process. After the tubes are installed, make a paper guide with the hole locations that you can index off the wing and put it aside until the painting is done. You will save untold hours of fiddling around those holes during the finishing process if you don't need to worry about filling them in, or sanding around them. FWIW. <Marv> ]
