I don’t think I would have tried doing something this ambitious without access to a ShopBot to cut the more complex parts like the hatch ribs and spars

dry fit hatch ribs and spars
I also used the ShopBot for some of the simpler parts that I probably could have made on the SawStop table saw with a dado blade. It’s just a lot more accurate than I could hope to be by hand. Since all the cabinet pieces are designed to fit into rabbets in the walls and floor to increase the strength of the structure I really wanted to be precise.
It is a challenge to do accurate 2 sided details. But thanks to Joe at The Village Workshop I learned a pretty simple fixturing technique for 2 sided machining. More on that in a later post
