Step 6The completed thread
The finished product is essentially an 8 conductor cable with a cotton thread core. This configuration provides flexibility and strength.
This thread is still remarkably thin and can be threaded through a standard needle. I have not tried machine sewing with it as of yet.
The best part is that the thread is insulated since the conductors are magnet wire.
In order to be conductive the coating needs to be removed and this can be done by heating it with a soldering iron at the desired connection point A little solder ball on the iron helps greatly. This coating is nylon and stinks like burned electronics when melted off. This is why you use cotton thread, the poly thread will burn away and greatly weaken the structure.
Alternately you can rub the thread with a very fine sand paper to remove the coating at the various points where continuity is desired.
As you can see in the pictures The coated thread is insulated and does not conduct even when the meter leads are place close together.
The final picture shows that a 1.5 meter length of thread with solder ends only has 1.9 Ohms resistance

I never would have thought of magnet wire.....
Thank you. Thank you Thank you.
