I lost my camera cord completely. I took the memory card out of the camera and put it in the slot on the computer and was able to download the pictures.

If we knew what we were doing it wouldn't be called research, would it?

You are right of course. I hadn't planned on giving up the idea, I may need to have a custom made auger build to really pressurize the slurry. Instead of a parallel sided axle to which the blade is attached, a custom made one could have a large initial volume then have the axle expand larger toward the ouput end to "put the squeeze to it". This is good since the outside of the blades will remain parallel to fit inside a pipe.
I mentioned I left my camera cable in Alaska so I can't transfer pictures right now. Maybe I'll borrow someone's camera that I can hook up to the computer.
I'm building the hot house with a pallet floor today. I need to drill lightening holes in the wood slats on the pallets to allow more air/drainage to occur.

You have a very interesting idea, Ron.
I wouldn't just give up on it unless you are convinced you have come up with a better idea. I don't know for certain that it will work well, but I encourage you to experiment enough with it that you can fully understand the capabilities of your extrusion method. Remember, no experiment is a failure if you LEARN FROM IT.
PICTURES!!!? ???
How about pictures of the parts and equipment you have so far and maybe a crude drawing of what you are thinking?

It is 6" diameter and 3 feet long and I figured it would be perfect to put in a pipe and push slurry into a box full of holes (for drainage) that slowly constricts (to build pressure) into the final shape of the wanted brick. This would create an extrusion of compressed PC and then one could have a hydraulic press (or a hand saw) that cuts it to length and put holes in the brick (if desired) at the same time. I was hoping to get 500 to 800 psi out of the auger. I don't know how tight a grain auger is but mine is tight inside its housing (6" PVC pipe for a test). Also I don't understand parts of Clair's statement "when you press you have to let the mix drain off for at least 6 hrs
