22 - A manual CEB CINVA press

Manual CEB (Compressed Earth Blocks) presses exist since Raul Ramirez created the manual CINVA press in the 1950s decade.

 

Ever since a number of designers and enterprises around the world have published and manufactured CEB presses based on this concept. There are also a number of Internet sites with links to drawings for this type of manual CEB press.
   

 
I have been searching far and wide but I have not been able to find any plans or drawings for one of these manual presses.  In the end I decided to create my own set of plans and drawings for the manual CINVA press. The objective was to create a set of drawings with all the pieces, dimensions and details for anyone to build one.
 

The press I drew and filed in the Google 3D Warehouse data base was for 28cm x 14cm x 10cm CEB blocks and is intended to manufacture one block at a time. It is really intended to be a tool for the entry level builder.

 

 

I have not built a prototype yet. A few details are missing by I am confident that all dimensions are good and will be useful to anyone with access to a small metal workshop.
 

I will update all the published drawings and plans and will share in this blog all the missing details as soon as I have built and tested the prototype.

But if anyone is handy enough to try and build a prototype before I do, please share with us your lessons learned. We will all be thankful for that.
 
I am available to answer any questions and clarify any doubts.
