Building Big
August 2003

This article was a presentation I gave at Brickfest in Washington D.C. in August 2003. It presents several building methods that can be used to successfully create large models made from LEGOŽ parts. Trusses, large composite beams, gears in high torque applications, and the modular approch to building are discussed with text and photos.
