Cracking Beans for Winnowing

A rolling pin and soil sieve suit my hobby needs at the moment but it doesnt mean that i havent considered speeding things up. Years ago i was looking aat getting a Novital Hammer Mill for this purpose but wasnt sure if it would be gentle enough and it was a bit expensive for an experiment. Well in a video from new chocolate maker Bright Chocolate in Australia just validated that it should be fine for cracking beans. Also the vid show the other kit they use and the equipment would be what i would choose so nice to see it working in practice. Yet to taste the chocolate.
