When the movement of the
gear units is exactly as you
want it to be, get started with
the outer small gear door. The
angles of this small gear door
are very complicated as well.
Basically, it is hinged with 2
Robart hinges, and connected
to the strut by a 2mm rod,
which has a clevis on on the
strut side, and a 90 deg. bent
angle on the door side, which
slides into a plastic tube, which
has to be glued to the door in
the exactly right position and
angle.
We use a “pull pull threaded
end” screwed into the M3
thread of the strut. In that the
clevis will be linked.
The linkage is so short, that
you even might have to cut the
clevis slightly, for sure you will
hardly be able to use the
thread as a length adjuster. Fix
the white plastic tube with a
veeery little bit of CA to the
gear door and start moving the
gear in and out.
Doing this, you will realize
quickly, howdelicate the setup
is, and all angles of the linkage
and of the tube are responsible
for the correct angel of the
gear door in extended and
retracted position.
Don’t give up, after 50
attempts you will get it right,
and from then on it will always
work without any further
adjustments.
Finally fill the joints of the hinge
with epoxy.
