@Georgemay

Nice coil jig, Your Earth battery looks like it will be nice.  I cant wait to hear your first readings

@All

Anyone that can make the wooden part of what georgemay has can take a old cordless screwdriver and put it on its side.. if you can manage to get your bolt in its chuck it will work as a makeshift winder to save your hands some toil.

@Bill

Im sorry you had to go through all that with wrapping and unwrapping but at least we learned about the salt.  your new one should be real cool. And sid was right in saying top to bottom , insulate layer then back up to top from bottom.

@ All:

I completed winding my second layer on the second cell.  I have a short somewhere in the second layer only.  Once I track that down and fix it, I will test and post results.  This thing looks dangerous.  I would hate to have this in my van and be pulled over by the cops.  They would never buy my explanation to what it really was. Ha ha.  It will look even better with the secondary.  And once we add the make/break contacts, well, homeland security might get suddenly interested.

Off topic story:
I was pulled over once in a very small town where I was working a week long surveillance.  One cop shoved me up against my van and stuck a Glock into my spine while the other searched my van.  They found all kinds of "contraband".  I had 35mm film canisters in my glove box. (I used 35mm film in those days)  They found zip lock baggies which I use for evidence bags.  And the really major thing they found was a cooler, which they emptied out onto the street.  This contained my lunch, dinner, and a two bottled water containers.  They said I was using the cooler to steal anhydrous ammonia. (for making meth)  Once the sheriff got there, he looked at my stuff and my PI license and apologized for his deputies actions.  He told me to leave town.  I stayed and completed my investigation.  Glad I didn't have this cell with me, they might have called the bomb squad.

I commend you with for your patience with those animals.  Dont get me wrong ive met normal cops and there out there.. its just when you get to the small towns they think there judge court and jury....

Often times ive thought about electrifying the hull/chassis of my car meaning the steel frame and all outside metal.  In so doing this not only would the animal be taken down the second they touched metal on the exterior of the car.. it would be possible to pull my vehical up next to theirs crank the juice a little and make sure the av equipment in the cruiser had a little zap for breakfast..  With a side of esd.  That hand held Tesla coil  from hack a day is starting to seem like a good idea.  It screams Back the hell off. 

Hi guys, i was just wondering if there was a limmit to how many layers of
copper and iron windings i can use, would it increase the current the more
layers are added..or is this pretty much unknown territory?.

cheers

chad.

@ Joe:

Thanks.  Most cops are good and very helpful.  Turns out, these deputies were not even sworn officers, kinda like volunteers.  Nice Tesla coil there!

@ Chad:

My thoughts are that the more windings you have in the primary, the better.  More surface area.  See what others here say as well.  I also think that the larger the gauge wire, the smaller and less layers you would need to accomplish the same result with smaller wire.  I don't know this to be a fact but we can compare our results here with everyone's coils and see.  I know we are using different wire sizes and layers so we might get a good idea about this.  Again, I really enjoy being on this forum and working in this topic.  I think we will have some interesting data to work with in just a few days.
