I was really hesitant to try this thinking the results would be poor and I'd prematurly age the mill. Really pleased with the results though :rocker: and so simpe! I just used an arbor from a brocken old angle grinder and turned up some flanges from 'bean can' aluminium. They clamp a grinding stone I already had and we were off to the races :)
