Is this even possible? I'm trying to understand Marx Generators. I know about how they charge up in parallel and discharge in serise. I've been reading about...
All, I had asked how to make entry hole in a stainless steel bowl. I tried a Dremel cutting wheels but results were ugly. Too ugly. I bought a Dremel...
Hello all, I am new to the group, and I thought I would chime in and share what I have found to work with my VDG. My rollers are both made of acrylic rod,...
Hi Craig: Welcome to the group. Your story rings a lot of familiar bells. I too have gone the route of many belt materials and find that vinyl impregnated...
... Hi Bill I might be wrong, but I dont think the sphere has to be a tight fit around the column. Its just the smaller the diameter hole you have, the more a...
What kind of resin did you use? If you can remember the brand or the product name (Castin' Craft for example, is polyester crossliked with styrene) I can...
Thanks. I am painting my "sphere-hole" with several layers of Dip-it plasitic paint(thats sounds nasty doesn't it?). I thought about an idea that was posted...
"I am painting my sphere-hole" - too much information. JK I am thinking that "Dip It" is the same as Plasti-Dip, which is vinyl (plasticized PVC). Using a...
Hi, I'm new to this group, I'm planning on building a VDG generator. I got two salad bowls with a diameter of 32 centimeters, made from stainless steel, only...
I've read some more old messages and noted that the belt must be between the two rollers on the triboelectric series. My belt material is vynil, and there are...
It's good to see you are being analytical but don"t carry it too far :-) You should experiment with naything you think might work. Design of a VDG can be...
... Hi iuliadumitru First off, welcome to the group. My VDG has a Nylon/PTFE (teflon) roller combination with a vinyl shower curtain belt. As an experiment, I...
I agree. One of the great things about building these yourself is the number of choices you have. You can try different things, but to really get an idea of...
... Hi Salad bowls seem very popular for terminals, thats what I use for mine. Your first problem will be cutting a hole in the bottom to allow it to fit over...
If you have a Target or an Ikea anywhere near you, they have rather large (14 inch) rim-less stainless bowls that have caught the eyes of many VDG builders in...
... Unfortunatelly, I'm far, far away, in Eastern Europe, so no Ikea round here :D. But I did find a someone that imports industrial wheels into the country....
hey i m new to this group and planning to make a vdg of my own i had some doughts. first of all can hollow rollers be used,i mean would they produce the same...
I don't see any reason why hollow rollers couldn't be used. That is similar to what many sparkys do to reduce cost. Use an inexpensive material to make...
thanks for the reply,well my friend made a vdg with teflon at lower base and nylon66 at upper.the belt was made up of an garden pipe,which was slitted and sued...
As far as cleaning, the only thing I can think of is to wash the belt and rollers in distilled water with a very small amount of detergent, then give a final...
I do not see any advantage to making a top roller smaller in diameter so it spins faster. This might lead to excessive bearing wear and mechanical vibration....
Dick, I suspect that Mangz might be trying to get a higher belt speed by having a large diameter bottom roller, even though he/she said smaller top roller, but...
Craig: Right on! I think a good exercise before designing a VDG is to look at the affordability ($$) of the desired terminal voltage which is mainly...
hey for the first shot i m going to use the below specification suggest me if some thing is wrong in the design. well i have finally decided to use bottom...

Dick, Having someone GIVE me a 4 foot long acrylic column (5" dia) was what got me motivated and inspired. Something I thought you might find interesting Dick,...
Craig: The gift was a stroke of luck. Acrylic tube is very expensive as you know. This between the belt charge you noticed must have been accompanied by a good...
