*Note: "Woodman Casting" is not a standardized industrial term (like "lost wax" or "sand casting"). It most commonly refers to two distinct practices: (1) casting molten metal directly into a prepared wood mold (risky/experimental), or (2) casting an object made of wood using a refractory mold (the standard interpretation). This guide focuses on the latter, most viable method: * Part 1: The Philosophy & Physics of Woodman Casting Unlike metal or plastic patterns, wood is anisotropic (strong along grain, weak across it) and hygroscopic (absorbs/releases moisture with humidity). This makes it both a beautiful and treacherous pattern material.
You are not casting wood . You are casting the absence of wood . The wood pattern burns, shrinks, or is removed, leaving a void that faithfully records its grain, tool marks, and texture. woodman casting
Pack unsealed wood pattern in dry olivine sand, pour molten metal directly onto wood. Wood gasifies, metal fills void. Risk: violent steam explosion if wood moisture >8%. Requires venting. When casting metal into a mold made from a wood pattern (Method A or C), follow these metal-specific guidelines: *Note: "Woodman Casting" is not a standardized industrial
