Practical home stone grinding Possible Duplicate:
  How can I grind coffee without a coffee grinder?  




I like my coffee super-fine.

I've had some luck with using regular coffee grinders and running it for a long time, but I'd like to explore (possibly manual) alternatives.  There are 2 reasons I want to try the manual alternative:

1)  Electric coffee grinders are extremely noisy.  This makes it kind of impractical to grind coffee at odd hours (which I love to do)

2)  My electric coffee grinder seems to be wearing pretty fast.

I tried the Kyocera "Hario Skerton" grinder which was eah.  It's a bit fragile, and when trying to get a fine grind you get a lot of crunching of the ceremic plates, which again will pretty much destroy it really fast.
Your best bet is probably mortar and pestle:



I've never used one for coffee until just now and it didn't take long to grind up a scoop of beens into a very fine powder.  When searching for a picture, I found lots of references to mortar and pestle being used for Turkish coffee, so super-fine seems to be no problem.
