I had to wait more than a week for my brother to help me pick up the Ply that I needed for the ceiling and now I have spent a couple of days fixing it in place. Its really good to finally have the cabin fully enclosed and its turned out to be a really nice and cosey space. and at last I can see how well my vintage lights work:

Of course the piece of steel that can be seen on the left of this picture will not be there once the glue is fully set because its just there to hold the ply tight against the cross tube while glue dries. I worked out it was better to have just two small holes that I can fill a line of screws that will eternally annoy me

The ply has something of the look of Burr walnut on the very smooth side I chose to use and while I was intending to just clear coat it I am thinking it would look nicer if I mix some of the Jarrah stain but diluted with clear so its got some of the wall colour but a few shades paler, the door linings I think will be done at full strength colour

To work out the right dimensions for the front ceiling panel I cut an off-cut and here it is test fitted
It took me the better part of a whole day to get this panel in place using a jack and a whole lot of swearing under my breath. the ply is actually a great deal stiffer than I expected it to be none the less it can be done as my pictures show and it will be immensely strong.

this final image is looking at the roof and the framing in the middle is there for my roof vent
