RE: Reproducing a canopy for the Blue Angel
Before attaching the canopy to the plate I first glued the stopper for the rear of the canopy in place. Then the canopy could be set on the plate and – once centered – a pencil line was traced around the outside.
A rather large gap on one side of the canopy precluded using canopy glue (the gap was the result of the factory being a bit careless trimming the canopy). So a mix of slow set epoxy, fumed silica and micro balloons was used, mixed to a moderately thick consistency. In the area of the gap the thickened mixture was stiff enough to fill easily. A couple of pieces of tape held the canopy down lightly. (Ron will be happy I managed not to leave any epoxy prints on the canopy!)
After the epoxy had set, I noticed a small gap at the rear that had not been filled, so a second small batch of epoxy solved that problem.
To recap, the epoxy's function is:
* to hold the canopy in position (very little strength needed for that)
* to seal and fair the edges of the canopy so the silicone won't get trapped in an undercut
