In reply to your side note: I've used foil as plate material for a 
rolled cap, and will keep on doing so since it workes great. I use 
50mm pvc pipe as a roll form and 110mm pipe for the container. I 
recently finished a 0,02+ uF cap that when rolled up moderately tight 
fit perfectly (0,5cm clearance roll-container on both sides) in the 
above mentioned container.
