Fit the windscreen
Mix 160 grams of flock and fill the entire joggle up to the level of the foam strip. Carefully
place the windscreen onto the bed of flock – start at one corner and position the windscreen
with a rivet or similar to get the alignment of the holes and then lower it into position.
Once the windscreen is in place start fitting the screws and locknuts, working from the
corners first and then the middle screws and so on in much the same manner as the holes were
drilled. Take care not to over tighten the screws, tighten them just enough so that the edge of
the windscreen is level with the adjacent fuselage.
Check all around to see that the flock has keyed to the
windscreen: the sanded surface of the windscreen
edge will appear to go clear with no bubbles when the
flock is in full contact with it. It may be necessary to
gently squeeze the windscreen to remove any
bubbles, although if you have filled the joggle with
flock there should be full contact anyway.
In the photo at right you can see that the flock is in
full contact all the way around. Note the flock has
been wiped off level at the outside of the joggle and
that there is no flock at all on the surface of the
windscreen.
When you are satisfied that the windscreen is positioned correctly wipe away the excess flock
with a clean mixing stick, taking care not to smear any resin or flock over the windscreen:
always wipe out and away from the windscreen. Do not use any cleaning agents; use only a
clean soft cloth.
Leave overnight to cure.
This completes the
Pre-Paint>Fuselage>Fit windscreen
task.
