The Gabriel Device, possible COP=8

Thanks to Mavendex (Dave) the shell arrived this week.

Now just got to sort out a insulator for both halves and wind that beast of a primary on the devil!!

Cheers

Clanzer,  Please tell us your M-417 wire gauge sizes and info specs for the inner and outer cores,  and how the cores were wound.  Number of winds per core and all if possible.  Did you weigh the nano perm before and after the winds?  Thank you.

I have been told that teflon tape is good up to 400F temp for insulating the doughnuts from each other

Hey Mav

Ive gotten some materials in to give the tube style idea a go. ;]
  It would be good if it has any hope, due to easier builds and especially while experimenting.

I think this is a great idea, Mags!  Tube style...  Can you tell us what materials you used, especially for the inner core with high magnetic permeability?  source? would be great!  Did you use a ferrite rod?

I'm finding that as I search for high-permeability toroidal cores, the manufacturers are in Germany and China... NONE in the USA!  I rather hope I'm wrong -- has anyone found a manufacturer in the US?

PS -- the supplier in the USA for larger nanocrystalline cores has run out of the largest ones they carry, 10 cm is on back-order, 4-6 weeks delay for delivery (from China presumably):

Hi Hope

On the M417 there is approx 2000 winds of 16AWG (approx 1.3mm)
16 awg 4.0156 Kohms per 1000 feet (.00473 per ft) 7.8177 pounds (3.5kg) = 1000ft

I worked out roughly 116mm's per turn

So 116 * 2000 = 232000 mm's
convert to inches
232000 /25.4 = 9133 inches
Convert to feet
9133 /12 = 761 feet

So resistance is .00473 per foot * 761 = 3.6 ohms

So around 3.5 kg of wire.

I ordered 4kg and still got some left over and ended up with 3.5 ohms. So pretty close.



Outer core is 9AWG (approx 3mm)

9AWG we will need about 350 feet, which works out a massive 6kg if my calculations are correct:

9AWG = 39.630 lbs = 1000ft, so 0.03963 lb per foot
1lb = 0.45359237kg
so 350ft *  0.03963 =13.87 lbs
13.87lbs = 6.3 kg

Again I ordered 4kg and plan to wind all of it and see what we end up with.

Did not weigh the nanoperm before winding but I am sure the weight is probably on the spec sheet somewhere.

Ya what did you get? I was only useing a galvanized steel tube with a made in china Iron stake... Can't even buy a iron stake made in America thats pretty bad.
