When you want to glaze the side windows of your model plane with clear plastic it can be stuck on the outside of the fuselage and the glueing overlap painted, however, it never works very well and there is always the problem of how well it will stick to the covering.
If it is stuck on the inside of the fuselage the windows will be sunk in, not very aerodynamic.
My way is as follows:
- Cut out the shape of the windows in a piece of plywood equal to the thickness of the window frame e.g. side of fuselage Fig A.
- Cut a base of ply the same thickness as A, draw around window shape piece and cut out 1mm larger all round Fig B.
- Cut a ply top layer of 1/8th ply Fig C.
- Now place B on bench, put clear plastic sheet (I used a clear lemonade bottle) on top with an overlap of say 1/2 inch position windows shape piece A over hole in B then place piece C on top.
- Using a domestic smoothing iron set to hot/cotton setting on top of piece C and press down until you feel it push downwards, the iron will heat the ply and melt the plastic and you will end up with Fig D.
- Trim around edge to end with a formed window which should be a nice fit in the frame, glue around the frame inside edge with slow Cyno or balsa cement and push in window until it ends up flush with outside of the fuselage.
- Before covering and glueing in windows it looks good if you paint inside the fuselage.
This type of glazing can be applied to other types of model and / or parts.
