It is then necessary to mill an oblong passage for the 2nd key of stab so that the stab can discuss
without hanging.
5.4 Montage du raidisseur de dérive
To cut out the stiffener member out of balsa of 40/10 with following dimensions:
20 mm16 mm280 mm
To sand with the large sandpaper the interior of the rudder and to stick the stiffener to the cyano
in the fixed part of the rudder to 8 mm in withdrawal of the left edge once that the reference of
depth, rods etc... are finished and installed
.
5.5 Installation of the wing rod tubes.
This work is delicate because it is necessary that the 2 wings are connected perfectly with
Karmans of the fuselage. It is a question of sticking the 2 aluminum sleeves in Karmans. For that
to proceed as follows:
To take a print of the wing root, by firmly pressing a paper A4 sheet on the root. Thus will appear
in the sheet and in relief the contour of the profile as well as the holes of the keys of wings. To
then use the print of the left wing on the karman right and vice and poured. Paper in relief then
will marry perfectly the karman fuselage, which makes it possible to mark with a punch the centers
of the holes of keys of wing through paper. The centering of paper on Karman is rather easy into
vertical but into horizontal it should be paid attention more so that the holes fall well opposite. To
then pre-bore with the diameter 5mm the 4 holes and to slip inside of the stems to check their
parallelisms and their perpendicularities in all the axes. To then thread tubes of interior diameter
8mm external and 5mm on these stems and to check good sliding motion in the sleeves of the
wings. Then to increase the holes with the drill of 9mm if they are well centered or with the round
file if should be caught up with some shifts. The sleeves aluminum must then re-enter a little in
force. To once again check parallelisms, perpendicularities and sliding motion with the wings
assembled with their keys.
To then stick the sleeves to the cyano to immobilize them. Then, it is necessary to ensure their
joining with sauerkraut of glass fibre and resin epoxy. For that to proceed in 2 times. To sand the
