32 Foot 4V Geodesic Dome: Top Down Test Assembly (Top Camera)

This video is a top down test assembly of a 32 foot diameter 4V geodesic dome. I had no way of attaching the cover using the bottom up method. So I used tripods and block-and-tackle to hoist the dome up from the sides. The tripods were made from indoor 2x4 studs connected together with a 3/8 inch bolt. The bolt was then bent inward to allow the tripod legs to spread out. For a solo assembly, this hoisting setup worked well enough up until the last row. The weight of the dome was around 250+lbs per section causing too much friction on the rope in block-and-tackle and could not be lifted single-handedly. A chain hoist would have been preferable at this point, as it has a higher mechanical advantage and locking mechanism. frame weight: 1200 lbs covering weight: 300+lbs total weight:1500+lbs Dome Specs Form diameter: 32.15 feet frequency: 4V class: 1 breakdown method: 2 (L3 from simplydifferently) Material struts: steel fence pipe 1 5/8 inch bolts: Grade 5 zinc plated steel 1/2 inch diameter 2 inch long covering: geotextile fabric coated in acrylic paint
