As I’ve mentioned, it’s always a little bit of an internal debate deciding how much to include on the lower deck when much of it won’t be ‘visible’ to the average viewer. Some folks who build this and other ships completely frame out the cabins on the lower deck, open up the transom windows (at the stern) so that all can be seen inside. I won’t be going that far, but I did want to include enough to be realistic as some is also visible through canon ports, etc.
To this end, I wanted to build the doorways to the stern cabins so there’s at least a backdrop stopping point to what is visible. I started with a firm template to measure out both the measurements and the deck slopes, and actually glued it to the beam. This allows me to me slide it in and out of the space until I’m ready to mount it.
Pretty basic stuff after that, measured out some framing and doors. I carved out some relief in the doors to give them depth and shape with some pin files in case someone gets frisky and tries to look down in there at some point. I gave that several attempts and this is about as straight as I can get those by hand.
