This set of barrels represents the enormous main battery of battleships USS North Carolina BB-55 and USS Washington BB-56.
These 3D-printed acrylic parts are designed to accurately represent features of the real weapons. They are not 3D-printed copies of any card, plastic or resin kit's parts and therefore may be shaped and sized differently than those parts.
Features:
scaled from scans of original builder's blueprints
barrels grouped on a trunnion to allow the modeler to set the position of the barrels to any realistic elevation from +45 degrees to -1 degree, just like the real turrets
Notice: this model is available in either "Smooth Fine Detail Plastic", an acrylic plastic, or "White Natural Versatile Plastic", a kind of nylon. White Natural Versatile Plastic is waterproof and strong, a good choice for Radio Control models and Combat RC models where durability is important.
Modelers find White Natural Versatile Plastic (nylon) unsatisfactory for static display models where surface smoothness and fine detail are important.
Sharp edges of models printed in white strong and versatile plastic appear less defined and more rounded than those of models printed in Smooth Fine Detail acrylic plastic. Being nylon, "White Natural Versatile Plastic" is generally not sandable and fewer types of paint and glue will adhere to it. Care is recommended in choosing a paint that will adhere to, and fully cure upon, nylon. Google "glue for nylon", "paint for nylon" and "primer for nylon" to find several good choices.
Customers report that "White Natural Versatile Plastic" will have noticeable striations (print lines). To help smooth "White Natural Versatile Plastic" surfaces, apply thin layers of primer meant specifically for nylon. Allow the primer to harden. Then smooth the hardened primer.
