 @woodland creature :pleroma_fox_tan:  Maybe one of us can build and share a brick extruder.  My brother has some local bricks from long ago that are extruded large clay bricks.  Like 12"x12"x5", I might use one of those as a pattern. 
 @Charles Zi Britannia i think we would need a multi-stage system that crushes, sifts, mixes water and extrudes with a big screw through dies 
 @woodland creature :pleroma_fox_tan: yee.  Smaller might not necessarily be cheaper for me since my dad has 3 100hp explosion proof motors just sitting hanging out in his barn.  Been trying to think of machines I can make that use those, the motors would be the main expense.  Bearings probably second. 
 @Charles Zi Britannia i want a continuous extruding and firing system that has a built in back hoe and gas fired kiln. 

 this is how my thought process prevents me from accomplishing anything
