Stubblefield coils (bifilar) and speculations

@ Gary:

Yes, I agree.  I will see if I can get some more wire and give it a go.  I have to re-think the cotton in between the wires for this one.  My trick with the string will not work as far as I can see.  And yes, I agree, it will not be easy, but hey, that has never stopped us before has it?  I will think on this some while trying to sleep.  This could be an entire new direction for us.  We will see.

I  agree ........we might  be on to something here.

@ Gary:

I was thinking, for what you were going to try it would be easy to use lamp cord. (Better known as zip cord)  This is available by the foot at most home supply stores.  It is just two copper wires that are insulated and stacked one on top of the other already.  Since it is flat, you could just stand it up on its side and wind away.  It is made of stranded copper not solid though, not sure what, if any, difference this might make.

I think I thought of a way to wind my pancake coil using the cotton string as before.  I like the idea of making the "jig" using two disks.  This might not be too bad to wind.  I guess I will find out.

@ All:

We had another aftershock this morning at 12:22 a.m.  This earthquake stuff is getting weird.  I hope my buried coil is not upsetting the balance of plate tectonics. (Grin)

If  the  next  aftershock  is centered closer to your house.............RUN FOR   YOUR LIFE  !!!!!!

I think I came up  with  a  way to make   pancake  coils  that is  pretty simple ........ reasonably durable  and  usable  on   both   insulated and  cotton  wrapped   wire .


I am  thinking  of  " sewing"  the coil on to a plastic mesh  of  some  kind .

If you have ever   really looked at how a sewing  machine  works ...... it is pretty simple .
The  needle   goes  through  the fabric  ....... into  the  base  of  the  sewing machine .......of course it caries  a thread with it . .........    as the needle  starts to withdraw ....a loop  starts to form in  the thread . 

This  loop  is  pretty predictable .....   we could pass a  " bobbin "  though the loop  and  pull   both threads tight ......then  move on an inch or 2  ...........every  5 or  6 stitches  it might   be a good idea to make an extra  stitch or  2  to act as a knot   in case  a thread brakes or something .   


more  details  later .......on  backing ,  needles  and stuff

Hi All,
(wow I am glad I went to sleep when I did. It all makes sense to me this morning.)

This is a really excellent suggestion - idea.

You can get el cheapo embroidery backing in the crafts section somewhere. Also, the name for the real backing for rugs or embroidery is "huck". Huck is a type of weave structure but this rug item has been called huck for a long time. The stiffness of these backings will make it easier.

Once a hippie boot maker showed me how to make that 2 thread loop.

He used a sewing awl which is a fat sewing machine needle attached to a handle that houses a bobbin of thread.
There was another source of thread which stayed on the bottom in a separate bobbin.

First, using the awl, he poked the threaded needle through the cloth
Then he pulled the needle back a little which made a loop.
Then he threaded the second thread (bottom thread) through this loop.
Then he pulled the needle back to the top side which pulled this loop with its extra thread to the center of the leather.
Then he made the knot snug by tugging the thread from all directions.
then he started the next stitch by poking the awl fron the top again... etc.

Gary, this is a great idea. I have been hand sewing the cotton around the layers in chad's design on the last 3 coils and sewing really works. It makes a very secure wrap with little effort or cost.

EDIT:
I just remembered another way.

Thread one piece of thread onto 2 needles and poke through the cloth.
Bring the thread to its center point in the middle of the cloth.
now sew from both sides into the next spot one from the top and one from the bottom and that is the first stitch.
Then move on to the next spot and sew from both sides again.
