   I found this on YouTube:   
      
   Molino californiano o de pisones   
   EDGAR VILLAVICENCIO   
      
   Clearly it's South America (?).   
      
   They use 2 countershafts - hence 3 stage speed reduction - from "Honda   
   GX(?)" motor to California stamps.  Using flat-belts.   
      
   If they do that, with likely huge collective and individual experience,   
   and ability to improvise, it looks highly likely that is the best   
   achievable non-megabucks solution.
