Set contains four (4) Base Rings for Twin or Triple 8"/55 cal. Turrets
Recommended for Iron Shipwright's 1/350 USS Salt Lake City CA-25
This set is designed to accurize any 1/350 scale USS Pensacola CA-24 or USS Salt Lake City CA-25 heavy cruiser model kit. In order to meet 3D printer requirements, these base rings are intentionally designed to be thicker than scale at the bottom. Once removed from their sprue, careful, gentle sanding of the bottom will thin these rings to a more scale-like appearance. Depending on which kit you own, some adjustment may be needed for best fit.
The bottoms of the two forward base rings have accurate shear (slope) so that they will meet the deck's shear but remain perfectly level on top, just like the real base rings did. The two aft base rings are designed flat.
These base rings have accurate bolt detail on two levels.
Each base ring is individually marked so that you will know which base ring is intended for the proper turret.
On the real ship, no matter whether the base ring supported a twin turret or a triple turret, the supporting base ring had the same diameter. True to prototype, these model base rings also have the same diameter.
The US Navy installed two 8"/55 caliber Triple Turrets and two 8"/55 caliber Twin Turrets on the ships of the Pensacola class heavy cruisers of World War II fame:

From Wikipedia: "The 8"/55 caliber gun (spoken "eight-inch-fifty-five-caliber") formed the main battery of United States Navyheavy cruisers and two early aircraft carriers. United States naval gun terminology indicates the gun barrel had an internal diameter of 8 inches (203 mm), and the barrel was 55 calibers long (barrel length is 8 inch × 55 = 440 inches or 11 meters).
"Mark 9: These built-up guns weighed about 30 tons including a liner, tube, jacket, and five hoops. A down-swingWelin breech block was closed by compressed air from the gas ejector system. Loading with two silk bags each containing 45-pounds (20 kg) of smokeless powder gave a 260-pound (120 kg) projectile a velocity of 2800 feet per second (850 m/s). Range was 31,860 yd (29,130 m) at the maximum elevation of 41 degrees.
"Mark 14: These guns were similar to Mark 9, with the same shell weight and maximum range, with a smaller chamber and rifling twist increased from 1 in 35 to 1 in 25 in a chromium-plated bore."
