Hand Crank Grain Mill Lubricants

As my mother-in-law was cleaning out my wife's grandmother's house my mother-in-law came across an old grain mill that she thought we would like. It is a nice, sturdy, cast iron thing that has clearly seen a lot of use in its day, but everything seems to work okay. :-)

So I took it apart and cleaned it thoroughly, but as I was putting it back together it occurred to me that I don't know what lubricant to use.

Any suggestions?

You can check on for food grade lubricant.  I just use food safe mineral oil, the kind you use for oiling wooden cutting boards....

Instructions that came with my Corona type mills say food grade mineral oil, but I've found that food grade grease can work a tad better.

Lard works very nicely on all cast iron. Not vegetable shortening!

I contacted my local food service supply and they ordered a tube of food grade grease. I bought a new grease gun, and installed grease fittings in the Diamant. Now just a partial shot of grease from the gun does the trick. I can lube it as it's running.

Note: you probably won't use a full shot of grease either. Bushings can have an open end toward the food side and while it's food safe, I just have to think that it's only sort of food safe. I don't know what's in it or what it's made of so I keep it to a minimum. That keeps the oozing to a minimum also.
