Default mill rpm

Why is a slow rpm better than a fast rpm for milling your own grain?

Just asking.

To fast and the mill will shred the husk and make a lot more dust.

I run mine at 175 rpm and it works great.

Ideally you want to squeeze the grain and pop the endosperm out without shredding the husk. Too fast and the kernel just explodes when it hits the roller.

Thanks. I have a monster mill that I have been using a 3/8 B&D variable speed drill and it's either fast or jamming up. I have been looking at this drill,

http://www.lowes.com/pd_300239-353-6335-01_4294857554_4294937087?productId=1208853&Ns=p_pr oduct_quantity_sold|0&pl=1&currentURL=/pl_DrillsC%2BDrivers%2B%2BBits_4294857554_42949370 87_?pageNumber=2$Ns=p_product_quantity_sold|0$curr entPage=4$totalPages=52

What do you guys think

Also would a steady crush give me improved efficiency?

I do love porter-cable tools. Never been disappointed with them or Milwaukee.

For that price you could pick up a 1/2 hp cap start electric motor on ebay then get a couple shivs to bring the RPM's down to around 200. With that setup you would have no speed variables in the equation, just one good constant. If you stick with the drill route Harbor Freight's will save you some money.

Thanks for all the replies. I just got home from lowes with the Porter Cable 1/2" drill. Nice drill and a 3 year warranty. Maybe some day I will set up my mill with a cap start motor and pulley set up.

I would suggest to beware of this approach. I know that the Barley Crusher (which might be a lot lighter duty) explicit recommends against it. Using a pulley puts a lot of sideways stress on the bearing, that is not present when using a drill.

Check out Ebay. You can get a good gearmotor for not much money. Of course with a drill, you can also use the drill for something useful besides crushing grain.
