The final piece of glass for the nearside turned out to have been cut incorrectly so I was very annoyed not to be able to complete the installation of the windows.  This means I cannot carry on as planned, so in the meantime my attention has turned to repairing the roof over the entrance.  The first two sections have been riveted in, the last piece should go in tomorrow then I will make the decorative arch fairing that goes over the door and under the roof cladding.
