A late afternoon pic today shows the sheet metal weather seal, and the aluminium shutter tracks. Fabrication of the weather seal was complicated because I forgot to make the diameter of the walls a little less than that of the dome. Therefore, the seal, which is attached to the dome, needed a step so that it would clear the walls. Truth be known, it could have done with a larger step as it binds occasionally - depending on the temperature.
