Part 2 of the box sections. Sorry no plastic
First the inner box , made to fit the opening in the frame. It just needs to be slightly wider than the card front.

Just trial to make sure it all fits, will only be glued together after all on the internals have been worked on, ie the brick wall , the doors and timber work of the barn.

Front on , just to give a idea of how it will look - minus the outer frame.

Now face down onto the glass and front . You can see the gap at the bottom right where the electrics, battery and switches will be. The outer case fits to the outer edge of the frame .

Black board is only because the supplier only had that to make up the 9 white boards he had for an order of 10. It's on the bottom anyway so shan't be seen .
The full back has been cut out, along with a cut out for a opening flap to access the bottom .
Hope fully tomorrow I can start the marking of the Kappa line sheet for the brick work and timber.
Thanks for looking in, comments welcome as usual .
John.
