Nynja Build manual 1.4d
Make sure there are no gaps, and that the Lexan is evenly positioned
with respect to the cabin upright tubes
tu34 on each side, and that
these are in their correct positions too.
k) While the two people hold the cowling in place, drill holes through the cowling
and the Lexan to hold it in place with white 4mm pan head plastic screws, and
black plastic domed nuts.
Check that the cowling has not distorted, particularly with reference to
the minimum 10mm clearance from the spinner
– the bonnet must be
secured in position before securing the lexan, or it may not fit
afterwards!
The curvature of the cowling can be increased slightly by lifting it in the
middle before fixing the windscreen, to increase space for the
c
arburettors etc. . Don’t over-do this however, as you will distort the rest
of the cowling.
Space the screws evenly, every 100mm or so.
Start with a hole in the exact centre (this will be used later for the
screen bracing batten
– don’t put a screw in yet).
To finally fix the dome nuts, use a drop of superglue inside as
threadlock
– don’t do this until you are ready for a final fixing – it may
be rather permanent
– we have managed to unscrew them, but they
might need cutting off.
l) If using the two piece doors drill and rivet the sides of the windscreen to the
cabin uprights tu34 .
The spacing of the rivets should be around 60mm or so. You can use
the silver aluminium 4mm rivets. Trim the excess Lexan so that it is
even with the rear of the tubes.
m) If using the one piece doors proceed to that section of the manual and fit the
glassfibre strip as shown.
n) Locate the windscreen roof centre batten
– you should have sorted it out and
put it aside when fitting the wing battens. Find also the screen centre batten
and joiner plug.
Cut the end off the roof centre batten to expose the hollow tube end. Fit
the small tube plug inside the end of the tube so that half its length is
exposed. Plug onto this the screen centre batten tube
Curve the ensemble to match the curve of the roof and windscreen as
precisely as possible. It may be necessary to trim the length of the
extension batten to fit.
Drill the roof batten (not the screen centre batten) matching the spacing
on the adjacent windscreen supports
Apply the thin self adhesive foam strip to the batten ensemble where it
will touch the lexan.
