Hi all,
a little while back there was alot of talk about milling grains, what could be used or what mill to get. I advocated DIYing your own mill like i have done link, but that got me thinking that it was not fair to say that because not everyone could get access to a lathe or 2in stainless steel stock. So i set myself a challenge to make a mill using basic tools and materials, this is what i came up with a mill with a hardwood frame and rollers made of PVC piping with a shaft in the center held in with concrete.
the tools and materials used
the finnished mill
the crush on a 1mm gap
list of materials
2.4 m of 135mm by 19mm tasmanian oak $30
4 * 6201 bearings (12mm ID 32mm OD and sealed) $2.75 each
500mm of 12mm bright steel shafting rod $18 for 6m length
1m of 8mm threaded rod $5
4 * 8mm nuts $0.35 each
255mm of 150mm hd conduit $100 for 4m length
coach screws $5
i went with such a large diameter in the belief that the rollers wouldnt need any "knerling" but found out that would only work if both rollers were driven so i had to put grooves in the driven roller so that the grain got draged thru so with that in mind i would probably go with 100mm pvc pipe that would cost alot less (i didn't by the conduit it was an off cut that i scored)
ill post a step by step instruction next week when i get more time, in the mean time others could post pics and details of there DIY mills to if they would like.
cheers matho
