I found another possible solution to this problem. I just bought a cheap 1000-watt gasoline generator for $130. What I'm thinking is that I can open it up...
Doug Many thanks for the emails, they arrived just fine, the pictures help clear up a lot of problems. I may well have a go at making something similar soon,...
When I try to view pictures I come up with blank rectangles for each picture. This is also true on another Yahoo group I belong to. Is this a Yahoo group...
Dick, I can view your pics ok. Try right clicking, with view picture. Maybe you have them blocked in your browser? Using IE, or Netscape / Mozilla? I use...
Im with Paul on this one, Firefox is a superb browser, its strongest point for me is the tab option, I usually have 3 wibesites open at the same time. But I do...
Paul: I use Mozilla and have never had a problem untill yesterday. I can view pictures as usual except on Yahoo groups! I'll keep poking around and see what...
Paul, Bob & everyone: FYI: I use Firefox as default and IE if I have to, like checking for windows updates. Paul was right it was the browser (Firefox!). In...
I have been looking on the net about electrostatic motors and sectorless ones like yours seem the most efficent. I found this web page on the subject, it...
I received my new 1000-watt gasoline generator this week and was able to put it through the paces with the large VDG. The generator is very small and easily...
last year we made a wimshurst machine and everybody LOVED it. but we lost the fair because it was a display (very cool hands on display) and not a experiment....
Scott, I think they're right about needing research and not just display. Disclaimer: Be careful when you charge up glass or plastic or oil insulators for bulk...
I'm glad that worked out, Dick. I'm a little sheepish that it was firefox that did it to you, though. Sounds like you've got a strategy (with your photo...
I got this from McMaster carr as a test to see how it worked and can't beleave how great it works even though it's black page # 3293 cat # 8811K55 it the best...

It's the number I thought I saw in the corner. I just finished my machine and it works great.It's 79" tall 22" gazing ball on top 3.75" belt made of .022"...
Sorry about that the page # is 3293 is's under polyester fabric I bought some at the same time I got the vynyl fabric and when I went to get more I could not...
Great find for belt material. You lucked out on the black! Apparently no carbon is used in the material. FYI: in the same vicinity in the catalog you will...
I know I thought black was not going to work that's why I got the vynyl coated nylon that I heard about from you also but this stuff is amazing I can turn...
The Weld-on works great for the vinyl belt since it is a solvent for the vinyl and you wind up with a flexible weld. What material are your rollers?? I am...
What are most folks using for supports? PVC pipe? I'm thinking acrylic sheets or rods to build a cantilevered platform but I'm wondering if a cheaper material...
1. Supports: I used acrylic tube for the first and fiberglass bars for the second. I suppose you could use other materials such as Sonotube, masonite, Texolite...
Tom, About your silk or cloth belt: I assume you are talking about plain cloth, not impregnated with a dielectric polymer like urethane rubber. Since cloth has...
An early article on VDG, possibly by VDG himself, recommends doped silk for belts. (i.e. nitrate dope for aircraft (or model aircraft)) I don't know if...
Compared to real life structural materials, acrylic is floppy. I've used unidirectional fiberglass driveway markers with some success. Mr. Linder's machine is...
I have also used fiberglass for my support tube, I layed it on a plastic tape covered cardboard tube, about 7" dia. When the resin had cured, I blocked off one...

Sounds like you have the same rollers top and bottom as I have on my smaller VDG. The big generator uses nylon on the bottom and PVC on top. The rollers are...
