Diamant review
Diamant Grain Mill (Lehman's)
By Tom Calder
A 56 lb cast iron mill with a heavy flywheel that keeps it turning, and the one Lehman's rates as the finest mill it has tried. It grinds bread flour by hand, plus beans and corn, and the pulley lets you add a motor later. Most households don't need this; it's for people who'll grind every week with or without power.
