Re: [ATM] Snap, crackle, pop, this is the pits

Chris...
   
  What are you using for a water supply..? City/municipality water is not good enough for fine grinding or polishing IMHO. The tolerances for particulate matter in city water supplies is virtually non-existant and particulates of 1/16th INCH are common in some areas. Of course these are usually filtered out or settle to the bottom and rest there until you need the water for fine grinding. I suggest that you use a 2-3 micron water filter setup as you would use for a refrigerator ice maker or purchase bottled (R/O) water for the finer stuff.
