Andrew: give up the 3" pipe you will never make it.  I use a heat sealer to
mount my plates in a plastic bag to keep them spaced properly. Your 6 mill
will work quite well. cut your 6 mill to the highth of your plates plus 2
inches. place one plate on your plastic  at the top and roll the plate
around the sides with 16 layers then place a plate below and on top at the
bottem edge and roll  16 more layers. That will give you one plate at the
top and 2 plates at the bottem  seperated with 16 layers of plastic . Now
put a plate under and a plate on top at the top and roll another 16 layers
of plastic. repeat at the bottem layer after layer. I use 10 plates and wind
another capacitor  I use 4 capacitors in parallel to get my total
capacitance. If each section is to thick you will not be able to make
connection to all the plates. I use pop rivets with aluminum washers as
spacers between each plate at each end with flat strap connections. My stack
is about 8 " x 12" x 5 " in size That in a plastec container of oil. My
students use smaller plates and assembel them in coco cans in parallel.
rolling the plastic around the sides of the plates keeps every thing in
place. After each section is rolled I tie each cap section with Nylon string
before final assembly.
