Top View of Grist Mill

Here's a view of where all the work goes on. The rollers are two inches in diameter by twelve inches long. They are cold rolled steel with a course knurl. One end of each roller was turned down to 1/2 inch diameter the other end was bored and tapped. I found a local machine shop to machine the rollers.

The tapped end of the driven roller has a five inch long half inch diameter bolt tightened into it for a drive shaft.

 

The end blocks are 5/8 inch thick aluminum stock. They house bronze lubricant free bushings that the rollers ride on. The end blocks were milled on an NC machine by a friend. I tried and tried to do it myself, but it was impossible to get the holes in the correct locations. The gap between the rollers is fixed at 0.045 inches. My friend Frank said he will machine new end blocks so that I can adjust the gap, but so far I haven't found a need to.

All things considered it cost me about the same amount of money as it would have to buy a quality commercial homebrew mill. My mill is a little larger (the rollers) than the JSP MALTMILL, but if I hadn't had the right friends I could have spent twice as much to build my own.
