It was a slow day at work so I built a VDG from junk parts laying around on my bench, to my amazement, it works rather well :) Small DC motor direct drive onto...
Guys, I have completed my second VDG it's using a 12" stainless sphere I bought at a garden supply center it's was $40.00 and soft enough to be Dremeled out to...
Zac: Congratulations!!!!!! Your roller/belt combination is the same as my small VDG. The big Vdg uses a white PVC top roller instead of teflon. The rollers...
Hi Guys, Just thought I would introduce myself! Having considered all the pluses and minuses (pun intended) I have made the leap and am buying up parts for my...

I recommend the belt that Dick said worked well, the vinyl coated nylon, it performs very well on both of mine and on my smaller one I tried all sorts of belt...
Hi Paul First off, welcome to the group, ive been a member for about a year and although it might not be the most active group on the net, the people here are...
Hi Paul: Welcome aboard. As stated in e-mails by others, take advantage of my photos of two very successful VDGs. You can glean many ideas from some of the...
Hi Gents, Thankyou for the warm welcome - always good to hear from folk who are passionate about similar ideas. Your hints and tips so far are exceedingly...
... Hi Paul Therabands are not the best material to use, they are too stretchy and tend to pop off the rollers and relatively high speeds. I use them on my...
Hi everyone, I came across a website: http://home.wtal.de/herbs_teslapage/theory.html#the-2ind on tesla coil design. I am wondering why is it that the author...
Paul: In choosing belt material the issues are always triboelectric and mechanical properties. I have tried different thicknesses of amber latex..... 010",...
OK, thanks guys. I am attempting to source a stiffer belt. If any UK residents can suggest suppliers then shout on up! Bob - I dont believe for a minute this...
Guys, Its done and now for the fun of jumping spaks around the house. I have gotten a 20" faint spark out of it to a grounded target!! and you all should try...

Hi all, I observe that the electrodes of High Voltage Source (for eg, a wimshurst generator) has 2 spherical shapes as electrodes. I believe this is because...
Glad to hear of the high performance, the shower curten material seems to be the best stuff around for high speed VDG's. The little program on listed on this...
interesting! the only thing i could think of was.... well if the spheres store voltage and not current...the sparks u are getting will be less voltage more...
Hi all, May I know what exactly is a Vacuum Tube Tesla Coil? The difference between a solid state and a vacuum tube tesla coil is that the latter does not have...
... difference ... latter ... Tesla ... I beg to differ, "Gomez". Although there may be other groups that specialize in Tesla Coils, I would welcome any post...
