I thought of this exact method just before reading this. Thanks' On Feb 7, 2010, at 3:31 PM, "Richard Schmuke" <rdj@xxxxxxxxxxxx> wrote:
I use 10ft copper pipes, for my coil operating spot and another set up at the base of my radio tower. Install a garden hose fitting on the end of the pipe , hook up a hose , hold the pipe vertical , have a friend turn the water and the pipe will slip right into the ground as the water pushes thedirt aside.

If your aim leaves something to be desired, hold a chunk of 2x4 on top of the rod, and pound that... much bigger target, and less likely to smack your hand. And above all, it is highly recommended that you slip the clamp, or other attachment device onto the rod BEFORE driving it in, as there is more than likely to be some "mushrooming" on the end of the rod, and it's a HUGE possibility that you won't be able to slip it on after. Stop hammering when there is just enough rod showing to comfortably deal with the clamp. --- Reverend Fuzzy Pastor, MSB Ministries Hattiesburg, MS http://www.msbministries.org-----Original Message----- From: tesla-bounces@xxxxxxxxxx [mailto:tesla-bounces@xxxxxxxxxx] On Behalf Of Brandon Hendershot Sent: February 06, 2010 7:30 PM To: Tesla Coil Mailing List Subject: Re: [TCML] Safely Grounding a Tesla Coil Hi Richard,A lot of what you guys are trying to explain seems way over my head.How about some advice for sinking a ground rod? Lol, but I think I will try the chicken wire counterpoise before I do any permenant damage to the lawn. Thank you all for your patience with me, Brandon On Feb 6, 2010, at 5:27 PM, "Richard Schmuke" <rdj@xxxxxxxxxxxx> wrote:Lets try this Brandon , if you have a antenna, the standard is a dipole , 1/4 wl out the center of the coax and 1/4 wl out the shield side. You can set this on the ground and have a rod going up from the center 1/4 wl, now from the shield side spread out several wires 1/4 wl length to act as theother half of the antenna. This is sometimes called a counterpoise.It gets more involved but did this help? If not I can sent you some simple drawings I use for my radio classes.

I've never heard of anything like it...Thanks btw, Brandon On Feb 5, 2010, at 9:39 PM, jimlux <jimlux@xxxxxxxxxxxxx> wrote:Brandon Hendershot wrote:Hi all, I know that it's said that you need an entirely seperate ground rod when opperating tesla coils because the high voltage grounding through the house wiring is extremely dangerous to anything plugged into any other grounded outlet on the same circuit.Not precisely.. You need a separate RF return for the coil, be it a counterpoise, good grounding system, etc. The reason you don't want it interconnected too well with the "house ground" is that it will propagate HV transients into your house wiring system (by capacitive and inductive coupling).. those transients wreak havoc on most consumer electronics. I wouldn't say "extremely dangerous".. I'd reserve that for something like juggling chain saws. But what if you attached the coilsground wire directly to the ground rod. It would be bypassing the house wiring, so the high voltage won't be running by any precious electronics inside the house. It shouldn't be running back up intothe house right?Exactly.. But there is a problem because at some point, you need tobond to the "green wire ground" at least for things that are plugged in or that you might touch (e.g. equipment cases).I'm trying to be minimalistic so I don't have to try to pound downa ground rod of my own.Think counterpoise.. a big conductive sheet.. chicken wire works well. A circle that has radius = the height of the top load above it. Hook that to the bottom of your secondary. _______________________________________________ Tesla mailing list Tesla@xxxxxxxxxx http://www.pupman.com/mailman/listinfo/tesla_______________________________________________ Tesla mailing list Tesla@xxxxxxxxxx http://www.pupman.com/mailman/listinfo/tesla No virus found in this incoming message.
