hello everyone hey my vdg is finally working. thanks to the expert guidance of all at this group that my vdg is possible. well i had problems initially.t he...
Been thinking about this: metal roller + auxiliary brush supposed to make the roller (-) which attracts (+) charges to the belt and are carried down from the...
I had some sparks but it was short lived. My direct drive lower roller was off enough to tear up the bottom assembly. So, I am trying to go to a belt, however...
Bill: McMaster-Carr (catalog on the web). They carry plastic pulleys and belts. I think you can see the ones I used in some of my pictures. McMaster will sell...
Lincoln, I suppose you could just connect the bottom brushes of two opposite van de graaffs together. But Why use two motors when you can use just one and do...
Wow... good job with the modelling Bob. Thats neat. Though I wonder if it would be a bit of a "Rube Goldberg" if actually built. Be cool to see... Ben...
Good Ideas Rudy. How big is your machine? Mine are small(8" and under) but I don't have a discharge wand. When I was in school the teacher had one with...
Dick, Sounds like someone with a time proven design should investigate its benefits or drawbacks for us. Sounds like your the man for the job... Ben ... to...
Well, the surplus houses like allelectronics, sciplus, or goldmine-elec on the web are easy, but if you don't want to go that way, you can make your own...
Well, that's the way I think because I can get motors for a small machine like that for somewhere between free and $4. ( Currently using part number G14783...
Where is the roller charge going to go? Unless it goes back onto the belt, it can't leak anyplace but into the sphere. The roller can't hold much of a charge....
Yes, that's really cool. Is that A.D. Moore up on the wall with Tesla? Seems to me you'd need to increase the radii on all the wilmshurst components to avoid a...
Ben: Thanks a bunch :-) Between my part time job at the TV station, taking care of a big Wurlitzer theatre pipe organ, messing around with PC based virtual...
Looking back into my collection of articles I saw something about a charging resistor connected to the roller. There is some vague comment about adjusting the...

Hi Lincoln I modelled the Van Teslahurst machine in a free, not shareware, 3D modelling program called Blender 3D. The whole package is only 6 meg, since then...
Thanks. That's a great tip. I'm probably going to model anything I build myself in the practice, home edition of Solidworks, since I need the practice. But if...
Hello Lincoln If banks, hotels and resturants mysteriously start loosing the tops to their trash cans, we know who is responsible for planting the idea!! Once...
I'm too greedy, unless I find larger ring molds. Do they have 3D Xerox yet? Note that a 15" lid was only $45 or so. BTW, if you want, conduct a late night raid...
Hello im a grade 10 student undertaking this has our project for advanced chemistry. Our final project is to do one for the science fair, I was wondering if...

Dark I'd start with a google search for van de graaff( also vandegraf etc because of spelling errors). How big of a terminal are you going to have? How much do...
This site has a lot of great information and pointers for a project like this, see: http://www.eskimo.com/~billb/emotor/vdg.html ... etc ... you ... can ... ...
If you're going to make one of these, you need to revise your ideas of insulators and conductors. At these voltages, wood acts like a conductor. You'll want to...
