20 Cabin Front continued
All the windows have Perspex inserts and will need an chrome look surround. these are made from 1mm styrene sheet, I pencilled around the window profiles and cut the external profile (the easy bit) I then drilled 4mm holes at each of the corners.
Next I made a simple jig which would allow me to mill the internal profile by hand, first setting the 3mm thickness and a couple of pins to stop the sheet lifting each piece was moved around cutting away the centre using a 2mm slot drill.
A final deburr and light surface sand (1200 grit) to make sure the chrome pen adheres well. these will be applied on final assembly.
