hi fellow coilers
      have just started to make my plate cap according to mike hammers
instrutions. I am using old litho plates which are roughly 18" by 14" this gives
me 4 plates 7"x9" if I chop off 2" and leave a lug 1" I end up withh 51/4" X 9"
so far so good. It then occured to me that this is going to give a greater
capacitance than mikes 6"x6" plates. 45^2 inches as opposed to 35^2 inches per
plate. As i need.0177uF for my neon according to tesla cad should I cut down the
size of the plates or increase the number of plates per cap from 24 to say 30.
another qeustion. has anyone used old litho plates for any lenth of time? I am
wondering about the print and the photo resist reacting with the oil over time.
It does not seem to want to come off very easily so I think to will be ok but
some feedbach would be helfull. btw thanks for all the help so far, the primary
is genarating a lot of interest " Hope you arent thinking of switching that
thing on when i am about" "I'll be away when you test it! shame" the cat is most
curious, and is my biggest fan so far.
