Product Description

Scale: 1/700

Set contains four (4) Base Rings for Twin and Triple 8"/55 cal. Turrets

Recommended for:

  • HP Models 1/700 scale USS Pensacola CA-24 (1941)
  • HP Models 1/700 scale USS Salt Lake City CA-25 (1944)
  • Midship Models USS Pensacola (1941)
  • Midship Models USS Salt Lake City (1943)


This set is designed to accurize any 1/700 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:

  • USS Pensacola CA-24
  • USS Salt Lake City CA-25


Some part cleanup will be necessary.  The 3D printing process uses a waxy substance to support certain part features during the printing process.  Although the parts are cleaned by Shapeways, some waxy residue may remain.  It can be safely removed with water and a mild aqueous detergent like "Simple Green" using an old, soft toothbrush, Q-tips or pipe cleaners.  Customers report that "Bestine" and "Goo Gone" also work well.

During the printing process, liquid resin is cured by ultraviolet light.  Microscopic bits of resin may remain uncured.  Let your parts sit in direct sunlight for a few hours to fully cure the resin.  Careful use of an inexpensive "air eraser" emitting common household baking soda can help smooth printlines and remove "frost" without removing details, before painting.    

Water-based acrylic paints meant for plastics is strongly recommended.  Other paints, especially enamels, may not cure on Frosted Detail 3D-printed plastics.  An inexpensive "air eraser" emitting commo household baking soda canhelp smooth surfaces before painting.

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).[3]

"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).[1] Range was 31,860 yd (29,130 m) at the maximum elevation of 41 degrees.[1][4]

"Mark 14: These guns were similar to Mark 9, with the same shell weight and maximum range,[4] with a smaller chamber and rifling twist increased from 1 in 35 to 1 in 25 in a chromium-plated bore."
