It has been a superb autumn day today so I was able to get lots done working outside. The first picture shows a last view of the inside of the fuselage before the baggage compartment panelling is installed.
The first job was to cut out a pair of rear windows from 2mm thick polycarbonate sheet. These were drilled and countersunk to match the cut-out in the fuselage.
I don't want to use any sort of frame which just adds unnecessary weight so the windows are going to be bonded and screwed to the aluminium panels.
In order to make sure that the join stays flat I drilled some scrap pieces of aluminium angle to match the holes in the fuselage and then applied a bead of Dow Corning 738 adhesive/sealant to the inside of the frame. The window sheeting was then clecoed through the window frame and into the aluminium angles. I'm going to leave it like this for at least a week for the silicon sealant to fully set. Then the aluminium and clecoes can be removed and replaced with #6 stainless screws.
With the windows in their final location I could then re-install the baggage compartment panelling. The aircraft looks very different and much closer to finished once the inside of the fabric is hidden.
