A while back I came acros a website that showed how to make an indian(from India) style grain mill out of cement. It was about a foot in diameter, eight inches high, had a hardwood central bearing and a hole for the handle.
I have lost the bookmark and can not find the website anylonger. I am trying to figure out how the centeral bearing worked, it both kept the top stone in allingment and allowed grain to be fed into the mill(it may have been keyhole shaped or two seperate holes).
If anyone knows whare tho find the website or how to build one I would like any info. Also does anyone know of any other way to build a homemad grain mill other than morter and pestol or the native way with a flat rock and a rooling rock.
