This is the projectile storage plan for Turret No. 2 at the rotating flats. Because it sits so much higher than the others, there is a third storage level below this that is unique to Turret No. 2. The turret support is a cone and the upper flat of Turret No. 2 is higher in the cone so it has less room for projectiles. So Turret No. 2 has many more projectiles than the others but fewer that are close to the hoists than in the other two turrets.
Here is a cross section. Sorry for the low resolution of this huge section for uploading. There is a circular Carlin beam below the Third Deck that transfers the weight of the barbettes to the turret support. This is were the support starts to taper
The upper projectile storage flat in Turret No. 1 is below the start of the taper. The upper projectile storage flat in Turret No. 2 is well into the taper.
This plan shows the access arrangements for the powder handling flat of Turret No. 1. Because of the narrowing of the bow and the torpedo bulkheads, the outer handling ring is pushed in. With some acrobatics you could climb over but you cannot walk through this narrowing.
This is the plan for the electric deck. As Mr. Smith mentioned, it is subdivided and each subdivision is extremely cramped. I have received many bone bruises moving in this area. You cannot move among the subdivisions at this level. You have to go down and back up or go up to the top and back down.
Iím not going to dig up all the frames Mr. Smith mentioned because there are so many of them. However, Frame 25 is in an interesting area so I will post it. What is happening here is that the bottom of Torpedo BHD No. 2 is a triangular panel that ends at the start of the bulkhead.
Here is my rendition of what is going on in this area. I have removed everything but Torpedo Bulkhead No. 2 and the decks (and the blue longitudinal structures below). You can see the triangle that gives the slope in Frame 25. The sloped area gets lower as you move forward until it disappears where the bulkhead ends at Frame 20. You can also see that Torpedo Bulkhead No. 2 rises in to the First Platform Deck this area to enclose the chain locker.
