Comparative Bell Casting Techniques, presented by Benjamin Sunderlin

Benjamin Sunderlin will share his research casting four 20-inch, 225-pound bells of the same profile in different molding and casting methods. These four methods – traditional swept-loam, English, resin-bonded sand via pattern, and swept resin sand molding – represent the primary techniques of bell production by which many carillons have been and continue to be cast. Despite centuries of bell production utilizing these methods, very little information exists publicly on the metallurgical and acoustic properties of manufacturing bells by comparing one process to another. Ben will share his experiences and insights with us from B.A Sunderlin Foundry.
