Show Solutions 4 meter (13.12 ft OD/11.22 ft ID), 4 sections

A conical circle truss built from 290 by 290 mm sections, measuring 4 meters across at 13.12 feet outer diameter and 11.22 feet inner diameter, and supplied in four bolt-together segments. Conical connections pull the joints tight and leave a clean tube-to-tube line around the ring, which matters on a circle that hangs in full view over a dance floor or a centre stage. Four segments is the practical split for a ring this size: each piece is still a two-person carry and the assembled ring goes together with a manageable number of connections.
