If you already have FGM Grain mill with Hand drive you can add this flaker mill as well. Roll your own oats, wheat, rye, etc. with this hand operated flake mill made in Germany. These hand-cranked flakers are designed to fit on the hand-operated clamp on system .The rollers are stainless steel and can be easily cleaned with a pastry brush. The Flaker is used most often to roll oat groats (oats purchased with hulls removed) but you can also flake wheat by adding 1 tablespoon of water to a cup of wheat berries and allowing to sit overnight in a sealed jar. Pull cover off flaker after rolling moisturized grain, to be sure nothing moist remains on knurled roller, because this would cause corrosion.
