Grinder

Millab M01

A beautifully built hand grinder for roughly $350, with a "pineapple" burr made of two heptagonal-style cones stacked into one long burr path.

Specs

AdjustmentExternal clicks from 0 to 100, plus an extra coarse range. The printed guide suggests about 0.125 mm per click, though that figure isn't certain 25:37
BuildThe burr isn't fixed to the axle, and the thin bottom plate may warp 28:42
Measured PSDD50 about 929 µm, D90 about 1587 µm 17:58
