Finger hole or not...you have got "pretty" down for sure. I'm not a fan of the hole, but then holes probably dont care much for me either.
I'll give you an A+ for shiny.
I like your idea Laurence. I have thought about doing that myself at our local farmers market. Our season is over for this year so that will give me time to figure out a setup.
I would like to hear how this works out for you....grinding in public...
