If you re making custom bricks for vaults why not make a wedge shape? That would make some sort of glue bond possible?

For the vault, the I don’t see why 1 inch on the thickness will help you with curve. If you are doing a Nubian vault (no forms) they are curved on the 6 inch side, not the 4 inch side. And either way, they is no problem making the curve with either side.

You should also consider inserts for the press to make different kinds of bricks, like a U brick for lintels, footing forms, bond beam forms, etc. Very easy to do, just make a wood block that fits into the press like you want. Also, half bricks are a good thing as well, maybe even some bricks with grooves for utilities.

Does anyone know of any free or open source plans for a manual press? The Liberator is an awesome design, but here in the developing world, we need manual tools to make it happen, like the CINVA ram, or something similar. Any ideas?

Pawel, presentlly, the machine is being tested with manual control valves for the two hydrauilic cylinders. We will be adding automatic control after that, as part of the work leading to product release.

We plan on using 6x12x4 inch bricks for the walls, and 6x12x3 inch bricks for the vault. It is easier to create the rounded vault shape when you use thinner bricks.
