Try kester acid paste flux formula sp-30 and kester silver solder do a google search.This is what I used on mine and it worked great,but you will need a good...
Hi Don, Yeah, it's been so slow that I've kept wondering if either my browser or the site server was broken. My generator continues to function in Westminster,...
Paul, I'd be interested to know your approach to maximizing the HV terminal shape. So far, the closest I've seen is a torus with a flat top and a sphere with...
Hi Don, ... Me too! I'm sure it will evolve as I discover what doesn't work. I'll assume azimuth symmetry. I can display in real time the shape of the...
Hi all, I am new to this group but I would like to build the smallest VDG I possibly can as a project for me and my son. Does anyone have a scematic or plans...
Paul, Wow, what a detailed reply! I'll keep my eyes peeled for anything you post. As for my daughter's hair, she and her friends decided to dye their hair for...
This past week, we were inundated with rain for several days. Consequently the humidity was high (close to 100%) with muggy dewpoints in the low 70s F. I...
Dan, I have to conclude that you did not build your "big model" VDG, otherwise you would know the materials from which the rollers and belt were made. Is it a...
Dan, I just looked at your photos. Guess I should have done that earlier. Yor "big model" VDG seems to be one made by United Nuclear. Nice looking machine....
WOW thanks Paul, That was way more information then I was expecting. For the collector I was going to try and not cut any holes in the garden globe. Using ...
I have a partially complete home made VDG. I am using a nylon roller for charging and a metal roller at the top. What materia belt should I use to generate and...
I use vinyl laminated nylon fabric. This material can be cemented using Weldon #16 acrylic cement. The cement is a solvent for the vinyl and the resulting seam...
Thanks for the input. I hope a metal roller will not cause any trouble? ... using Weldon #16 acrylic cement. The cement is a solvent for the vinyl and the...

Hello all, I replaced the 4.5 inch diameter mixing bowl with a 8.5 inch jello mold and fitting lid. I had to make the support column longer to stop arcing to...
Hello all, where is everyone? I just added five new photos to my album showing little VDG version 1.2. The latest improvements are bearings to the top roller...
After several failed attempts at a VDG , I now am carefully choosing my materials and construction. My problems in the past has be stablility and tracking...
what you should have is a belt that is conforming to the shape of the roller because you want as much surface contact possible for maximum charging, but I...
If the edges of the belt are not touching the ends of the roller then the benefit of the crown will be minimized at the very least and tracking will be tricky...
Hello all, I just measured the top terminal voltage of little VDG version 1.2 to be around 150kV. The short circuit current was 1.1 uA. I am not getting 1.3 uA...
