At what point is the spark gap too wide and what harm will result? Doug J. On 5/13/2015 10:18 PM, David Speck wrote:
Doug,For starters, tape a thumbtack, pointy end out, to the outer circumference of the toroid. For a quickie hack, just rest a small screwdriver or scrap of solid wire on top of the toroid, with the sharp end pointing out, perhaps a half inch from the perimeter of the toroid. That might allow you to get streamers to air without a ground rod.Dave On 5/13/2015 7:05 PM, Doug wrote:I am new to this, how would I run it with a breakout point?

Have you tried running it with a breakout point?You might consider raising the secondary coil to be even with the bottom of the primary, for better performance. Any turns below the bottom of the secondary are producing a voltage contrary to that produced in the upper half of the secondary, effectively reducing the length of the secondary and lowering the net output voltage.Dave On 5/13/2015 1:31 PM, Doug wrote:Doug Johnson here; I finished assembling my small coil, complete on its 8 inch base and made a short video of it in operation. I am using a 6kv-30ma NST to power it. The caps are 2- 102-30kv doorknobs, the secondary is 6.5 inches of 24 awg on a 1.5 inch coil-form. This is my second coil, the first one I had a set of plans for, and this one was designed using Teslamap and asking MANY questions of Bert Hickman, which he showed great patience in answering! {thanks Bert}Here is the video. https://youtu.be/mqqd1vPy8Ko Doug J_______________________________________________ Tesla mailing list Tesla@xxxxxxxxxx http://www.pupman.com/mailman/listinfo/tesla
