Hi Langsley You asked >1 do you any sort of mechanical stirring while producing your CS with > the Spartan 9KV-30 HVAC? I added mechanical stirring a few months ago, before that I would stop the process every hour to stir. I bought a Radio Shack 1 1/2 volt motor, powered with a universal adapter, pushed a 3/16"plastic fluted rod called a Ny-Rod from a Radio Controlled Airplane,(my other hobby) onto the motor shaft, a perfect cheap stirring device. >2 have you had occasion to deal with the vendor, Utopia Silver, to >resolve >problems or answer questions? If so, how were they to deal >with? I asked Bill Fernald if I could order the machine on approval, and he was very accomodating. I have since called him a few times and he has always been helpfull. I have had no problems with the generator. The generator has pretty good current control, starting at 18ma, ending at approx 25-27ma. the unit comes with several feet of 12 gauge .9999 silver wire. I changed my setup from the two rod system to 4 rods as recommended by Bill, this helps to reduce particle size. >3 You mentioned having Frank Key test your finished product. What did >that >cost per test, $ US? Frank's price list can be found at www.colloidalsciencelab.com/LabServicesPrices.html Hope this helps Dave Sawatzky
