How do they do this? Any idea?

[SuB-ZeRo]

Thaks Bruce i looked to the web site that u post me but all of them for copper or other materials none of them can winding hot lead wire.Hot lead wire has a problem.If u wind the wire too fast it shrinks.If u wind the lead wire too slow it damages.That means i need a winding machine that has a speed control unit.

Here is my project that i want to do.

In the picture 10 there is a lead wire makeing machine that i do.I use the lead wire to make (diablo) 4.5 mm bullets.We have to winding the lead wire by our hands .
You can see a picture of winded wire on picture 13.
And a have an idea for winding this wire.The project has 2 parts
1.wire winding control unit.
2.speed control unit (that must be resistant to the hot)

I can imagine most parts of the project.U can see the picture2 that i want to control the speed.It is simple to do that.

my real problem is in picture 1.
how can i dedect the wire to be defeated from the winded wire?How can the winding control unit can understand the right timeing to make a good winding like the picture13?

I really need good ideas or suggestions for this.If somebody make a project like this plz help me.Coz i am stuck
