Does anyone out there have any *experience* actually building large capacitors? Say, for example that I wanted to build a 5000 uF capacitor that can withstand 1000 Volts, how do I go about doing it? (Yeah, I know... *VERY* *CAREFULLY*!!!) I have read several descriptions about how to build simple capacitors, (stacking sheets of wax paper and aluminum foil), but this is a bit beyond that. I would like to hear from someone that has _actually_ built some serious capacitors. To the best of my knowledge, such things are not readily available. If you can pick these up through a vendor, please let me know about them. Please reply directly to the me. Spare the Net traffic. Thanks in advance. - milt ...rochester!kodak!ektools!milton

Well I'm no EE type (CS), but when I was in high school (back when doing things like building
"real capacitors" was worth doing just to do it), I made 3 different killer capacitors.
1. rubber cement foil to both sides of a sheet of glass (I used a large window pane).
2. etch foil off edges of double sided circuit board (again I used the largest one I could buy).
3. etch edges off several single (I used 6) single sided circuit boards then stack them
and connect the alternating sides with foil. Clamp then as tight as possible.
Why did I do this? Well I had a 12,000V neon sign transformer, that just had to be played
with...
