My DIY grain mill
 

Just finished up the machining on my DIY grain mill. I just need to get a base and hopper made for it now. Hopefully, I will get some free time this weekend and can finish it up!

Wow, nice! :mug: I'd be interested to hear more about how you sourced materials, how you did the machining, final cost, etc. Is is adjustable? Looking forward to seeing the results of the milling.

How are you doing the knurling? I wouldnt mind building my own if I could find shafts.

All the materials used in the mill was scrap that I found at work. I did all the machining on free time. The rollers are adjustable. They are 6" 1.500" 1018 barstock that I knurled and turned down on a lathe. The frame is .500" aluminum plate. As far as price, it didn't cost me anything since it was all scrap. I would like to rig up an electric motor to drive it since I don't have anything in it so far.

The knurling is done with knurling rollers on a lathe.

Did you make it adjustable? I have a lathe I'm rebuilding and thought this would make a decent project....as far as I can tell, the adjustment requires some sort of cam action/eccentric movement of one roller. Not sure how that might work....

It does. The knobs that stick out are the eccentrics. They are simple to make. You just machine the bore for the bushing off center. Then the knobs rotate in the frame itself. The long bolts that stick out are used as a set screw to keep the knobs in place once the gap is set allowing the roller to turn in the bushing.

Hi HDBrewer, the mill looks good :). I'm in the process of making one myself. Even am not sure how the eccentrics work for adjustments. Can you post a few more pics of the plates with the bushing/bearing.

Thanks!! :)

Have you tried it yet the knurling looks a little fine (not criticizing just asking) making one myself so wondering. Nice work

That is impressive!! Good job! :mug:
