My son and I have built a Mosquito Helicopter here in Costa Rica and we would appreciate some help on the steps to build a compound curved windscreen over the pilot ht tp://www.i nnovator.m osquito.ne t.nz/mbbs2 /boxx/know ledgebase. asp?Type=4 &Cat=5
We have built a single foam plug that defines the shape of the windscreen and the streamlined nose cone that will contain the tail rotor pedals and on the inside an instrument panel. The windscreen part will be attached to the mast over the pilot's head and then join the nose cone at the pilot's knees. I have experience building fibreglass molds and my thought was to build the female mold from the plug then do the fibreglass nose cone and the windscreen separately from the mold? Or should I melt the perspex over the finished Male Plug(finished in Bondo)?I have never worked with Perspex so I appreciate any advice to get this project started in the right direction

Then, trim to fit the canopy structure, and attach with fasteners/trim ring.

You will need a large oven to dry the polycarbonate and to do a good job for forming compound curved surfaces. Simple straight bends can be done with a strip heater.
There will be a plastic sheet fabricator in your region. Possibly he will be a large outdoor illuminated sigh manufacturer. He will have a large oven and expertise. He may be prepared for you to contribute effort in the mould making under his advice and direction, while he makes the moulding from that mould.
Plastic sheet suppliers will be able to ofer technical bulletins with fabricating techniques and details. They should also be able to advise someone in your region who has a suitable oven.
