Using SketchUp to Create a 1:72 Scale Model of an Iowa Class 16" Battleship Turret

More progress on Missouri Turret interior.

Working on the pan deck after detailing the ofc’s compartment bulkhead. I have to constantly remind myself that the ultimate model will be 1:72. That means the entire bulkhead is only a little over 5" wide. That’s small, but there’s a bright side; I can print the entire bulkhead in one piece. I’ve delineated the elevating gear and am thinking about how to make the guns movable, but that may not be necessary since the model is going to be under cover. I still have some geometry issues. For example: the port side guns shield is hitting the wall of the Pan Deck. I don’t want to move the guns so I may have to make the pan deck slightly larger in diameter. There are some errors that need correcting like the lack of thickness of the pan deck floor. It should be as thick as the lip rising up from the Breech Clearance Pan at the bottom.

The guns elevator by way of a large lead screw surrounded by a hydraulically driven rotating nut. The gun turret traverses by another hydraulically operated motor turning huge pinion gear engaged with a ring gear that surrounds the entire pan deck. I’ve yet to draw either gear and many need help drawing the ring gear. There are two pinions sets driving rotation. All of this hydraulic stuff is there so there’s no chance for an electrical spark anywhere near the gun floor. The pumps and electric motors providing the hydraulic impetus is one deck below on the electric deck. That’s the next drawing challenge.

There’s the giant optical rangefinder and the manual aiming stations that need creating in the gun house.

Still have a lot of drawing to do and still waiting for the kit and metal gun barrels to arrive at the hobby shop.
