Frankacony:

This is a design sketch based on the original [[CEB Press/Rollers]] sketchup file. This is not done by an engineer so this may not work.

The idea is to make the roller easily extendable, fit a specific length or curve with different types of guiderails. Also this can be assembled by hand via wingnuts.
The guiderails can be 2 + x elements long. The curved guiderails are supposed to be hand-bendable into any curve / configuration.

In a curve, the ubars are directly touching each other on the inner side. The ubars need to be wide enough to leave space for the movement of the rollers. Therefore the curved guiderail could live without the horizontal support featured on the straight guiderails.

In a curve, the ubars are directly aligned to each other on one side of the roller, while the ubars are wide enough to leave space for the rollers. Therefore the guiderail can live without the bottom support of the straight guiderails.

=Introduction=

The Liberator is OSE's automatic, high throughput (up to 16 bricks per minute) Compressed Eearth Brick Press. It is named The Liberator because it is intended to free people from the single highest cost of living - housing. See [[Cost of Living]] and [[GVCS Naming Convention]].
==Status==

*Avoid code uploading frustration! [http://opensourceecology.org/wiki/CEB_Press/Manufacturing_Instructions/Code_Upload How to upload code to the Arduino microcontroller]

*Avoid excessive hydraulic pressure! Make sure you have a correctly installed pressure relief valve on your hydraulic circuit. Start testing the CEB Press with a low pressure setting on the pressure relief valve.

*Avoid hydraulic fluid leaks and non-motion! Check that all hydraulic connections are tightened/connected and theoretically leak-free.

*Avoid premature sensor latching! Check that the sensors are mounted parallel to the magnets.

=Overview=
[[File:Liberator_bricks.JPG|right|400px|thumb|Bricks pressed on [[The Liberator]]]]
The '''"Liberator" Compressed Earth Block Press''' is a machine that makes compressed earth blocks ('''CEB'''s).

The [[CEB Press]] takes earth/dirt/soil and compresses it tightly to make solid blocks useful for building. Compressed earth blocks have many advantages as a building material: by making the building materials from the readily available dirt on the building site, they eliminate the need to transport bricks from elsewhere, reducing financial cost and environmental impact. Compressed earth blocks are very strong and insulate well against both heat and sound, making for very energy-efficient building (especially combined with the energy savings from not needing to transport them from offsite). Best of all, the material they use is already on-site and does not need to be purchased -- quite literally, dirt-cheap! See the wiki page on [[Compressed Earth Blocks]] and the [[:Category:CEB|CEB category]] for more details on building using CEBs.

The Liberator has been fully designed and tested by the [[Open Source Ecology]] team. Because the Liberator is an open source technology, you can freely download instructions to build your own from materials you can obtain yourself, or contact ''opensourceecology[at]gmail[dot]com'' to buy a kit or a finished machine.

Building a machine yourself might seem intimidating, but every step of the process is fully documented and the OSE community is available on our [http://forum.opensourceecology.org/ discussion forums] if you need help, advice, or a little hand-holding.

Using the CEB Press, two people can build a 6 foot high (1.83m) round wall, 20 feet (6.1m) in diameter, 1 foot (30cm) thick, in one 8 hour day, though construction time will vary somewhat depending on preparation time, what equipment is available (tractor to prepare the ground and move the blocks where they need to go), the quality of the soil, and other factors. The bigger the block size, the faster a wall can be erected, but at the cost of heavier blocks that are more of a strain to work with. Blocks from ''The Liberator'' average 25 pounds (11.3kg).

See [[CEB Design]] for more information.

Frankacony:

To facilitate ergonomic CEB distribution to build walls (we estimate several tens of thousands of bricks to press, which can present problems with strain trying to carry each brick from the press to the walls and columns where they need to go, not to mention wariness), a number of roller modules were designed and built:

<html><iframe width="560" height="315" src="https://www.youtube.com/embed//5RzZp11ujP4" frameborder="0" allowfullscreen></iframe></html>

<html><iframe src="http://sketchup.google.com/3dwarehouse/mini?mid=97ef71054fe788efe81b05614741e304&etyp=im&width=400&height=300" frameborder="0" scrolling="no" marginheight="0" marginwidth="0" width="400" height="300"></iframe></html>

We found it easiest to install and lock the legs first by laying the roller frame on its side, and then the rollers (there are 40 per section, we presently have 5 sections). It also works better with at least two people to help manipulate. Once the rollers are installed, it requires at least two people to move the segments around.

Detailed manufacturing and assembly instructions will be forthcoming.

Here is a modified version of this roller [[CEB Press/ModularRollers]]
