To build the dome, we needed a dual angle miter saw to cut the wood. It had to have AT LEAST a 60 degree angle capability, and the blade had to tilt a minimum of 20 degrees. Good saws aren't cheap. We paid about $650 for this 12" Dual-Bevel Sliding Compound Miter Saw (6955-20) from Milwaukee Tool. It has a digital read-out angle with repeatable accuracy to 0.1" degree. The Integral Dust channel captures up to 75% of the dust and debris cut, which is nice to have. I can't imagine how much dust there would be without it!
This is halfway through the build of our icosahedron 3V 4/9 dome. The dome is about 12 meters (40 feet) in diameter and about 6 meters (20 feet) tall. To help with calculations, SimplyDifferently.org is a great website and uses the metric system - so be prepared.
At first, we were going to build a dome 7 meters (23 feet) in diameter and bought the following lumber:
Our first project was to build a greenhouse to house an aquaponic system. Tom wanted to construct a hoop house, but I wanted to build a geodesic dome. Why a dome?
