| Hi Alexis, Bob the builder has one he made with an air assist bottle jack similar to those you mention from HARBOR FREIGHT. There are many that have been made with no hydraulic advantage some are quite inventive. If you are interested in one at a time brick making here are some videos. http://www.youtube.com/watch?v=sPuMqgKaX24 http://www.youtube.com/watch?v=gaiYKDyUtAk http://www.youtube.com/watch?v=1CoECgnqtXg&NR=1 And here is a group that made CEB bricks for a structure with it fairly automated. They even built the tractor and its implements. http://www.youtube.com/watch?v=nV_-ZzYmo3A&feature=related This is a little different than PC but the basic principals are the same. In a place where water is scarce you would want to collect your "squeezings" and re-use them to make your next batch. I've been toying with an auger to drive PC through a compression mold. I has taken back seat to other projects. Bob and I have both become enamored with the small T-lock block molds.

Takes away the need for a brick press completely. Ron --- On Sun, 3/28/10, alexis.marcil <alexis.marcil@gmail.com> wrote:
