The Roof Windows & Window Frames.
I started with the three roof windows by making a template of the window apertures which I could then transfer to some 1.5mm clear Lexan sheet and cutting and trimming all of them to be a friction fit in the roof apertures.
The Lexan is thin enough to be easily shaped by scoring a snapping and the edges scraped and filed to remove any burrs or rough edges.
The roof windows on the real Pilot Boats have a heavy tint to make looking skyward up to a tall vessel alongside a lot easier in bright daylight and I simulated this by applying some window tinting film that is normally used on car windows.
This film was bought as a ‘sample size’ from an eBay seller and is described as ‘Limo’ which means it only allows a 5% light transmission.
The film has to be applied to the outer surface of the ‘window’ using a combination of soapy water, lint free cloths and rubber squeegees and to be honest is not at all easy to apply 😠 without getting trapped air or specks of dust or other contaminants that cause microscopic bubbles and bumps in the process, but after persisting I managed to get some passable results 😊.
The film was left to bond to the Lexan overnight before it was trimmed back with a sharp scalpel blade.
The roof window frames need to be made as narrow as possible so these were made from 1mm styrene sheet cut into 3mm strips which were glued together to form the frames with fillets fitted to the inside corners while overlaid on a paper template.
When the glue had set the frames were removed from the paper backing and the internal and external corners rounded with files and the framed flatted on both sides to smooth them and provide a good surface for painting.
The paint finish is two coats of metallic silver and a couple of coats of clear lacquer.
Fitting them into the roof was very straightforward, the friction fit was helpful to hold them in place while canopy glue was used to fix them, the thin glue was applied with a fine brush around the edges of the windows and capillary action drew the glue into any gaps between the Lexan window and the ply roof panel.
The frames were also fixed down with canopy glue applied as a series of dots around the underside of the frame and held in place with masking tape until set. Any excess glue is easily wiped away with a damp cloth and it dries completely forming a very strong bond.
When all the glue had set the windows were polished with a soft cloth and I think that the overall look of the roof windows is very good 😎.
