Big a$$ project of the day
Overheard at MDRA in the aftermath of a rain shower: 20' tall, 20" diameter, 150lb, N2000. Custom tube, 1/16" thick. Lots of discussion on non-standard building techniques internally. The guy had pages of mechanical engineering calculations to show it will be strong enough (compressive forces and the like). Me asks, why is he building a tube and having to mess with the internals? Answer, he wants to keep it light. But, that's backwards of what most people do - find a tube and build the nose cone. Answer: he got the cone from a movie set or some such (2nd hand info) and needed to build the tube to match. Sounds intriguing.
