Hi list,

For those looking for suitable motors to stir their CS during its production, 
here are a couple of sources:

Both have the same 110 volt 60 Hz AC motor which rotates at 30 RPM.  It is a 
timing-style motor, originally designed for use in microwave ovens, measuring 2 
inch diameter by about 0.8 inch thick.  The output shaft is 0.16 inch square 
about 0.27 inch long.  Price is about $2.50.  These should work better than the 
small DC motors which run at hundreds to thousands of RPM.  Stirring should be 
gentle so as to not dislodge "sludge" from the electrodes.
