Hello all,

            I have a 500 kV VDG but would like to use a spray charge on 
the bottom. The top roller is metal and the bottom is plastic.

I NEED -ve on the sphere. What would be the best type of supply to use? 
Also how close to the edge of the belt can the spray bar

(using pins with the heads cut off) be?

	I've always had good luck using bits of window screen with a wire or two pulled out crosswise to make the other wires stick out into the open further.  Dumb desciption but you can probably figure out what I mean.  Lots easier than soldering cut off pins to a piece of metal, which is what I did in the days of long ago.
