18.2.2
Fitting the Lexan
a) Cut out the Lexan sheet from the patterns.
Use a large pair of tin snips. The patterns are supplied as a guide, and
your individually constructed doors may vary slightly, so cut oversize
initially to be safe.
b) With the door in position offer up the Lexan and mark some reference points
to align with the door frame.
For now it should be positioned accurately against the hinge, and centred to
provide an even overlap all the way around its other three sides.
c) Before riveting mark and drill the holes on the doorframe.
Use a nominal rivet spacing of 60mm. Try to drill in the centre of the
tubes or it will pull the lexan out of shape. Lightly marking the centre by
drawing a long flexible metal straight edge across the frame can help.
d) Drill and rivet in place the lexan using 4mm aluminium rivets.
Remove the protective coating from the inside face of the Lexan, leave
it in place on the outside but remove it using your fingernail around
each point to clear the rivet heads.
It is advisable
to fix with cleco’s/skin pin’s first before rivetting
Work from the upper front corner, and rivet the front edge first. Follow
this by riveting the lower edge. Due to the curve in the central cross-
piece the rear edge will have to be worked around the curve, to avoid a
wavy edge.
It may be necessary to drill out some rivets and reposition the tension in
the Lexan slightly to get the best fit
(cleco’s/ skinpin’s used first will help
avoid this). Do not be tempted to put more curve in the central cross
piece to give greater shoulder room or you will turn this into an
impossible task! Finish by riveting the upper cross piece and then the
central cross piece.
When drilling angle the drill slightly away from the last rivet. When
squeezing the rivets bring the rivet upright. This then applies some light
tension to the Lexan and prevents the Lexan bulging between rivets.
Take care when drilling to ensure the tube is drilled centrally.
e) Fit the door and mark carefully the overlap for cutting to final position.
The front and lower edge should be cut to match the recess. The rear
can overlap the rear window, or another glassfibre strip can be used.
