Ronald Remsberg builds complicated structures from simple materials. In fact, Mr. Remsberg has built several scale models from nothing but matchsticks. A former Convair aeronautical engineer and builder of free-flight model aircraft, Ron used thousands of these sticks and Elmer’s glue to assemble models of some of the world’s most famous landmarks and structures. Ron has built about a dozen such models since starting in 1998. Though he has slowed down a little, the structures remain very square and precise. Ron noted that building the projects is a great tension reliever. This comparatively large matchstick model replicates the London Tower Bridge. The bridge is about 71″-long. This was Mr. Remsberg’s first attempt at making a matchstick model with moving parts. The two segments of the drawbridge can be raised or lowered. The Tower Bridge took nearly five bags of matchsticks (almost 10,000 total) to complete.
