Archive for the ‘Geodesic Dome’ Category
Dome construction continues. All of the pipes have been measured and cut. 20% of the pipes have had their ends crimped and about 15% have been drilled. To give everyone an idea of how we plan on constructing it, I created a basic diagram. Since I projected the 3d structure onto a 2D surface, things don’t exactly line up correctly. Hence, edges that look like that should be shared probably are.
You can also find a 3D rendering of a very similar dome (minus the doorways) on Google Sketchup
All dome struts have been measure and cut. All that remains to do is to crimp all of the ends and drill holes. That shouldn’t take TOO long!
We are attempting to construct a 3V 5/8 geodesic dome for Toorcamp with a radius of approximately 12 feet. This means that the longest strut in our structure will be 5 feet long. In addition, we intend on adding one doorway into the space allowing f The materials needed include the following:
- ~ 850 feet of 3/4″ EMT (electrical conduit)
- ~ 61 5/8″x2″ bolts
- ~ 61 5/8″ wing nuts
- ~ 122 5/8″ flat washers
- Floor of some kind
- Covering of some kind (likely a modified parachute)
Assuming each foot of conduit weighs approximately .5 pounds, we can guesstimate that the total weight of 165 or so struts is approximately 425 pounds, leaving plenty of allowance for other gear that will be brought along as well.
