Dome building methods - flattened conduit

The flattened conduit is another method looked into for possible construction. This Process involves flattening the end of some metal tubing bend it slightly then drill a hole. Do this to both ends get yourself a bag of bolts and you can easily build a dome framework.

Advantages: 

• Easy to assembled/disassembled, no special tools required, just make sure you don't split the tube when you flatten it and that you flatten enough so you can put the bend in without interfering with other struts. 

Disadvantages: 

• Quite crude. Also this type of dome framework is usually covered in canvas or similar material, which can be quite difficult to get tight and crease free over the structure. Also of the unevenness of the joints can make it difficult to cover cleanly.
