Nautical Foundry Pattern - Letter J



Nautical foundry pattern manufactured by Sun Shipbuilding & Dry Dock Co. This handmade wooden pattern was used in the process of sand casting. Molding material, such as sand, would be packed around this pattern inside of a casting flask. The sand is then compressed in a process known as ramming. When the molding material reaches the proper density, the pattern is removed. Molten metal is then poured into the cavity created by the positive mold. Once the metal has cooled and hardened, the sand is then broken away and the metal casting is removed. This pattern was used to cast a part of a ship or nautical component. Foundry patterns are hand-fabricated by skilled tradesmen known as patternmakers. It takes many years of experience through apprenticeships and trade schooling in the fields of carpentry, moldmaking, and tool and die making to achieve this title. Many view patternmaking as an art-form due to the precision and skill required to build a pattern by hand. Nowadays, retired foundry patterns can be repurposed or upcycled in a myriad of ways; from rustic wall art, to funky furniture. Weight: 32 lbs.
