I have been experimenting with home rolled Caps and would like some help with values please?Using food saver tubes as the dielectric, dielectric is 36" X 8", foil inserted in the food saver tubes is 32" X 6", uf measures 14uf as rolled. What would be the voltage rating? So far I have used one in a small TC [7.5k NST] and have not destroyed it! All-tho it buzzes loudly.Doug J. -----------------------------------------From: "jimlux" To: tesla@xxxxxxxxxx Cc: Sent: Friday October 19 2018 11:17:01AM Subject: Re: [TCML] Brush copper plating onto polystyrene On 10/19/18 8:59 AM, Matthew Sweeney wrote: > Good info, although I'd still like to find someone who has done similar > work with one of those inflatable exercise balls.. that would be an awesome > VDG terminal :) It's out there in the archives.. Except it was a kid's bouncy toy, the name of which I cannot remember, they have a loop sticking out of the top that you hang on with. When I worked at the effects shop, we made some large "pendulum bobs" for a sort of "giant executive toy" (https://www.amazon.com/JoyTech-Newtons-Collision-Decompression-Psychology/dp/B07921155N) /> using those things, somewhat overinflated, covered with fiberglass, then spray painted aluminum. They weren't heavy enough without the fiberglass to swing like we wanted, but for an electrode, maybe ok. A hole will cause it to deflate. You might be able to figure out a way to inflate and deflate it, but for a VDG, you need the hole for the belt, so using it as a form upon which to make something rigid. If you want a plastic hemisphere, a good way is to build a box with a plywood top and a circular hole. You lay a sheet of plastic on top, heat it with radiant heat, then use a vacuum cleaner to pull a vacuum under it, and it will form a nice hemisphere. Let it cool, repeat it, saw the flange off and join it. But a spherical buoy might be a cheaper way to go..
