Hi - see http://www.info-central.org/?article=303
Always over design for 1 pin anyway. If you use 2 pins rate the powder use
for three. Too little is much worse than too much - YIKES! Pins must be
symetical. Then ground test and you want separation with some authority -
but hitting the neighbors house with your nose cone is not a good idea..
