Anyone ever used heavy angle iron or tubing with the blind elevators for wood deer stand? Wondering how high I could go without cross bracing on a 4x6 box.
Unless you use 6" or bigger well casing, anything taller than 6 or 8 feet (without cross-braces) will SWAY ;
get conditions just right (continuous med-strong winds), and the swaying could oscillate and bring the whole thing down ( google 1940 Tacoma Narrows Bridge ).
Having 6 or more posts (instead of 4) could help - but cross-braces are much cheaper way to eliminate swaying.
