Elements to assemble

structure
The reproduction of this machine requires some expertise in order to assure a
correct result. Despite our efforts to simplify and optimize the designs we strongly
recommend
only professional blacksmiths and welders take part in the the
assembling
of the various pieces.
The material required to reproduce one of our machines are:
- Band Saw
- Drill (up to 16mm)
- Welding Machine (or Electrode)
- Grinding Machine with cutting discs, stone discs.
We want to spread our knowledge on Compressed Earth Bricks (CEB) by distributing
assembling and usage manuals of different CEB machines. This distribution is to
be done for free! If you possess one of our manuals you will be able to assemble
your own proper press. Make sure you read carefully all our annotations and follow
the instructions to assure the best possible results and to prevent you from taking
any risks.
With this press, which we named
Sophie
, users will be able to make building bricks
300mm x 150mm x 90mm by compressing a mix of sand, clay and eventually
some stabilizing cement.
We believe sharing knowledge is the best way of achieving an equitable
development in communities throughout the world and the cooperation between
humans is crucial for our growth as a society.
To reach the final objective of reproducing the press
Sophie
you will have to
produce 5 separate pieces to finally assemble them all together.
Sophie
is composed by:
earth hopper
lever
piston
lid
