2 story revolving stage
This is a 2 story stage that rotates 360 degrees around a cast iron pivot bolted to the main stage and a cast iron sleeved bolted to the bottom of our stage. The 20 x 20 foot bottom level is framed with 2 x 10s with joists 2 foot on center and utilizes 33 casters with a 330lb capacity each. First level decking is 7/8 chipboard with 1/4 plywood skin. the second floor uses 2 x 8 joists, 4 x 4 posts and 3/4 plywood decking. The stage was built for a high school production of "Noises Off" by myself and a crew of high school students in 4 days. All power tools utilized, except my 12" mitre saw, were Ryobi 18v saws drills and drivers.
