Hey everyone, I think it is really great there is a group like this...I am pretty new to all of this and wanted to ask a question. I am in the middle of ...
Jeremiah: Hi and welcome. I think rollers with "retention edges" are nothing but trouble because they do not do what one might hope, and that is to prevent...
Thank you so much for your response, it was extremely helpful. Its funny but you would think that the "retention edges" would help, but you are exactly right...
Jeremiah: So glad to be of some help. The most important thing with the top terminal is the smoother the better. Paint will not improve anything but might...
OK, so I have what may be a silly question. While working with my Wimshurst machine charging various models of homemade Leyden jars, I thought about the setup...
... Hi Paul, This will indeed work. Every time the spark gap fires, you'll get a complex pulse of high RF voltage at the top of the Tesla Coil secondary ...
... top ... Interesting. If I adjust the spark gap on the Wimshurst to fire quickly, wouldn't this help the charge in the Tesla build? I mean, how often does...
Hi Richard and Jeremiah I have had some problems at home and have not been able to talk to anyone for some time but now I am back. Re your comment Dick about...

Trevor: I suppose I should have been more specific. Of course you can paint the dome but you have to wind up with the same (or better) smooth surface that you...
... Hi Paul, Most Tesla coils "fire" somewhere between 100 and 400 times a second. In order for streamers to "grow" properly, you need firing rates of at least...
Richard and Trevor, Thanks guys for all your help! I fired up my VDG last night and it made about 1 inch and a half to 2 inch sparks. My hair on my arms stood...
Jeremiah: If your electrical wall outlet was properly installed, the screw which holds the cover plate on can be used as a ground point. If you choose not to...
OK... I don't know where to begin, so I'll just start with a tiny background. I'm looking to build Christmas presents for family members who, like myself, just...
Dick, Once again you give out great advice! I did what you said and it is working great...we have sparks, raised hair,a rice crispy volcano, etc... My daughter...
I was shopping at the local grocery store recently, and while on the aisle for household cleaning products something caught my eye: scrubbing pads made of...

I am new to this and going to try and build a VDG. I would like to know if a teflon (PTFE) upper roller and a PVC (gray) lower roller would work ok for this?...
Hi Lyonel Does this mean that the newer version may put out more volts or are the 25’ domes at their maximum potential at a certain humidity before the air ...
PVC and Teflon are very close together on the triboelectric series, you would have to find a belt material that would charge the teflon negative and the pvc...
I heard this story of the radio the other day. Very slightly off topic, but I thought the energy released when peeling tape would be of interest to the group :...
a nylon 6/6 roller will work, nylon 6 not and if you keep a Teflon bottom roller your machine will charge positively and apparently that is much harder to do,...
In my Mk-II machine I use a felt covered bottom roller and an aluminum covered upper roller. The rollers are cylindrical furniture rollers that already have...
My experience - vinyl impregnated nylon. Lots and lots of stuff has been posted about this material.pros cons and where to buy. This does not stretch which is...
