Geodesic learning curve

4 May, 2010

The geodesic dome project continues.

That is not EMT.

A prototype vertex created this weekend.

  • Nobody in Ireland has heard of EMT or arbor presses.
  • “Vice” is spelled “vise” in America.
  • An English Wheel is not a torture instrument.
  • The Noisebridge hackerspace nerds are a friendly bunch and will let us use their tools.

  • Levers are a nerd’s best friend.
  • This is going to be expensive.

* especially when you can only find GRCinstead of EMT. Oh, the crunching and grinding and agonised noises 😦

** Technical term πŸ™‚
