Time is ticking before Product Release of The Liberator. Some last minute adjustments are forthcoming, before we release Beta Version 1.0. Here are some scenes from field testing.
First, we carry it over to the work place with the LifeTrac forks. LifeTrac makes for Air CEB, but The Liberator Prototype II weighs 1922 pounds total.

The machine was buried 3 feet down to facilitate soil loading, while the support legs rest on the surface. The soil grate was added.

Second, we use the Soil Pulverizer/Loader for the first time in the CEB workflow to grind a pile of soil. Since rainy weather did not allow for a single day of soil digging for this entire month, this soil is from inside the workshop – we’re lowering the floor.

Then the Soil Pulverizer/Loader dumps the soil into the 6′ wide hopper, which is getting its first use under real working conditions:

Third, we turn on the Power Cube – which you see in the background in the above photos riding on MicroTrac – for the first time in the real CEB application, and press bricks using 10 gallon per minute hydrauilic flow at 2400 PSI.

Compared to the Liberator Prototype I, the bricks are thicker and smoother. Both are features of the finer soil filling the compression chamber – achieved by both the Pulverizer and the grate. The compression chamber fills more completely and leaves no traces of grain boundaries in the pressed brick:

The white spots are gravel chunks, care of our workshop floor.
Our observations so far are: (more…)
