Keith:  I successfully ran a test batch using the heads and middle portion 
of the distillation (light alcohols and ethanol).   The wash test and 
methanol tests showed a complete conversion.  I used 28% alcohol by volume.  
The 
more dilute tails go in a barrel to be run again at a later date. I recently 
built a 25 gallon compound fractionating still.  Soon I will put it in to 
operation to make 96% pure ethanol in volume.  Lee.
