OSN-1: In order to bring you the very best kits, we used a wonderful new technology which is known as stereolithography. All of these kits used 3-D CAD and stereolithography to produce the master copies. This technology is very expensive, but it is superior to the standard techniques used by most cottage industry modelers. Stereolithography uses a laser beam and a special laser sensitive material. Directed by the computer aid design software the laser produces parts to the exact toleraces found in the historical blueprints. The attention and reproduction to historical detail as found in all of Old Steam's kits is without precedence in the world of modeling. We are so sure of our claim we actually include the 4 pages of original blueprints as part of our instructions. Old Steam's kit contains resin barrel, a new pewter seacoast barbette carriage, 3 shells, 3 bolts; 6 iron spherical shot. There are over 35 parts in all! We hope you enjoy your model kit. Please tell your friends about us.

History: Captain Thomas Rodman, responsible for increasing and improving endurance of heavy ordinance, changed the current foundry methods for casting large hollow cylinders. He revived a long abandoned hollow casting method with a critical difference. Captain Rodman substituted a patented 'core-barrel' cooled inside by air or water. His idea was to freeze molten metal from its bore outward, pushing impurities toward the exterior. He understood that casting as an outward succession of thin concentric rings that in turn while cooling would solidify and then shrink. The shrinkage would compress those already cooler within, producing compression stresses to oppose firing pressures. Today, this technique is known as pre stressing. The 10-Inch Rodman gun (Pattern 1861) weight was 15,050 pounds; had zero preponderance. Confederate Columbiad's copied Rodman's construction.
