There are many commercially availiable earth block press machines for sale. I want to make - and maybe improve if I can, on a current design so that I can produce blueprints for free distribution. Are there any sites/plans out there to get me started on making a prototype. I am a draftsperson in California. My goal is to make a full set of plans for an easily made CEB press to post online for anyone - in any country - to download for free and make their own press. The web actually has no sets of plans you can download for free. Even portions of plans I have seen have no measurements to allow someone to fabricate one. My intention was to try to find a working set of plans, that had no patent and draw them properly (I have years of CAD drafting experiance) and get them online so that people could build the presses with basic workshop tools.
You might try buying a press; disassembling it, measure the individual parts and then draft the components into a set of drawings. You can also go to the Patent Office in Washington, DC and review the files for previously patented presses and you can find ones that have expired. Or you could find a current press manufacturer and become a distributor. I've lived in a number of third world countries were block presses are used on a regular basis and they are an income producing trade. The press is considered a capital asset and giving them away would be frowned on.
