     I just finished taking readings of a new stack plate capacitor I 
     built.  I used a Quadtech precision LCR meter to take these 
     measurements.
     
     C = 42.5 nF
     DF = 0.0000759
     ESR = 818.73 microohms
     
     all measurements were taken at 100 kHz.
     
     The capacitor is made of styrene and Al foil (Reynolds Wrap Heavy 
     Duty).  There is  a 1 1/2" guard region around each foil.  The styrene 
     layers are 9"x13" and consist of two 20 mil sheets between each foil.  
     The stack is sandwiched between 1/4" sheets of lexan and tied together 
     with nylon straps.
     
     I'm constructing a vacuum tank of 3/8" Lexan.  I will immerse this cap 
     (and its soon to be born siblings :) in this tank, one at a time, 
     under oil.  After degassing under vacuum, the caps will be transferred 
     to a epoxy coated wooden box, which will be filled with oil.
     
     Has anyone had success/problems constructing a vacuum chamber out of 
     solvent welded pieces of polycarbonate/acrylic/etc.  Also, what kinds 
     of terminals have capacitor builder here used in their homemade units?
