Topic: screens for testing grinders (27 lines)
1) From: jim gundlach
Friday I went by the recycling center to drop off stuff and while I was 
there I went through the different kinds of tuna and cat food cans.  
Found a clean one that seemed to be shaped right so I brought it home, 
cut a good hole in the bottom and JB Welded a piece of the #42 screen 
to it.  This #42 has thicker wire than the standard #45 so the holes 
are almost exactly the size of standard #45 screen which is the finest 
one in the standard set.  I stacked the screen on another can put a 
spoon full of the surplus ground coffee that I have on hand now, ground 
at six notches up from contact with the Rocky, and shook it for a 
couple of minutes.  It ALL went through the screen.  It is obvious that 
finer screens are needed to evaluate espresso grinds.  Next, I'll get 
cans to make a screen with the #50 and #60  and see how they work.  
With the screens I have, I will be able to make my set and provide 
screens with instructions for making three more.  Two have been spoken 
for so there is only one more available. Once everything is done, I'll 
post complete instructions including what to order to make additional 
sets if people want to make more.
