 Star Dome Model with bamboo sticks |
I have still some thick bamboo (2-2.5cm in diameter), and I tried to split it 4 times, but with a knife it didn't work that well and the resulting splits were very uneven. So, I used again my 40cm long and 4mm prefabricated bamboo splits (bought in a garden shop). I tied with with plastic cable binder, no glue.
Junction of 5cm as bamboo stick is very stiff

Tightening the cable PVC binder with a pliers

Finished the 15 bows, composed by 30 bamboo sticks
2006/04/14 10:34 | | 
Marking the 10 bows with 25cm marks (3 marks per 75cm)
2006/04/14 10:41 | | 
Starting the layout

The resulting bows where 40cm x 2 - 5cm as junction: 75cm long.
As next I did the layout, forming the pentagram and the pentagon around:
Pentagram, holding with cable binders, junction at the marks

Pentagon surrounding the pentagram, using plastic binder again

Closeup double junction
2006/04/14 11:00 | | 
Closeup pentagon surround the pentagram

PVC junction/connectors |
Therefore I required a 150cm long circumference as base, where the bows will be attached as well. On the base I added two PVC tube, making 4 connectors, actually I only require for the star dome 3, but I may use the material for another model later.
Then I began to put all the open bows to the base:

And so forth, step by step
2006/04/14 12:45 | | 
All 10 bows attached, due the stiffness of the bamboo sticks not yet a dome

The pentagon star on top

As next the 3rd bow for each base need to be attached as well, first I made it go outside of the existing dome, but it didn't fit, so I put the 3rd bow inside to form a better dome (the sticks are hard to bend and rather stiff), the result was a much better dome then.
Attached the remaining 5 bows to the inside, gets now better in shape to form the dome

Finished star dome (PVC binders need to be cut short)
