@ gary,
Hello there mate, havent seen you for awhile, are you ok
Nice to see you again.

@all, the wife has been in hospital again, so had to down tools for a while, she had a small stroke, infection in a lung, and a headake, she is back home and on the mend.

I have been watching this  thread ..  I just ran out of money for  expermenting 

The  stuff related to this thread that I would do if I had the money  would not  be cheap
I would   try a large  stubblefield  coil .    I think we  have the  basics  down  but  we  don't  have enough power to  make a magnetic  switch .            Once the  switch is working then  it would be time for  a secondary .

Another thing I would do is   try  the  large  magnesium   annodes and   carbon cathodes to see how much   usable  power   they  could  provide .  I think the  larger  ones are  rated  at 1 A
If I remember  right  they  can be  wired in series   as long as they are far enough apart to not  short out .      I would wire them  to provide  between  12 and 15 V   then  hook them  directly  to a  couple of  deep discharge   batterys    ..   an inverter  could be used  to  power stuff in the house .  It would be interesting  to see how  much  real power  it would provide .   




I hope you  wife is getting  better fast .

@ Gary,
I agree totally with your theory, I think we need to pile the turns on, then see how the cell performs.
Making small coils has given everyone a lot of experience, and sore fingers, but like you said, it takes money to make a big coil, me being a pensioner dosent leave me with much to go and buy everything I need but I cope ok.
But, and its a big but, when someone gets a breakthrew, and gets some current from his (her) cells, then whacko.

In the middle of december I'm going to shell out on a frequency meter, but  this is for HHO stuff, but then again, NS coils operate on frequencies also, so I can justify the expence.
Now I got to get my hole punch out and make a few hundred holy rubber washers for the above, its for another bloke.

I duck into Bills thread from time to time to take a look at it
I see jeanna has changed her avatar, it looks OK.

Wife is on the mend

Jim

Hello,

Could you guys give me the specs on a large NS coil (or point me in the right direction)?

Thank you

Carl

@ Carl,
Hello and welcome to the group.

Carl, 1st off most people have made only very small coils in this group, that said, there is no limit in theory to how big a coil should be, but this depends on how much ready cash one wants to spend, the price of copper wire being the biggest outlay.

As the size of the coil increases, so does the weight relating to the amount of copper and iron wire turns you put on.
The same also amounts for the length of the iron rod you begin with, then there is a limit on how big the whole thing will be, and I'm talking about how much weight you can handle on 1 hand while winding the bifillar winding, and not mucking it up.
Then there is the fingers, they get sore, and I mean sore with the constant handling of holding 2 wires together while winding them.
If all that dosent faze you, then go for it.

My 1st job as an apprentice in about 1967-8 was to hold 6 copper wires together in 1 hand, to make up a rectangle profile whilst wrapping cotton tape arround them, each completed length was about 10' long and I had to do about 30 sets, to be used on a huge starter motor for a generating plant, phew, that was a superman effort which took me quite a while.

If you intend to use or make up a winding jig, then go for the big coil.

I reccomend you get a copy of the Nathan Stubblefield Patient and read up on it, there are previous posts where you can find it.
There is Bills Nathan Stubblefield web forumn which is also very good, click on the HOME icon, and look for Pirate88179 entry.

You will need a lot of patience, as this one (NS coils) is not giving it's secrets up willingly.

But first off, take a look at Billo's UTube on his experiments he has posted, (see below addies) its very good and try your own setup with copper and aluminium rods, see what happens with that. Just to give you some experience. Read up on earth currents etc etc.

Any one know some sites to get deals on copper and iron wire for the coils, and advise for the wooden spool stublefield put betwenthe primary and secondary windings?
