This method of winding that is supposed to have a more concentrated flux field than normal "back and forth" windings and should be an advantage in motor coil performance.
The gauge of wire being shown is 22GA and the length of wire is 40 ft however you can do any gauge and length you want for whatever you are working with.
Be sure to use "motor rated" magnetic coil wire which can withstand high temperatures and has double coats of varnish.
1) Wind first layer like this:
2) Pull back straight the end of first row over the top of first layer that has been covered in tape to protect row from chaffing or shorts from contact with straight-back portion of wind.
Teflon plumbing tape can also be used instead of the black electrical tape shown, or you cna use both types too.
Teflon will withstand temperatures to 400F degrees. :
3) Cover straight portion of wind with tape on the top of it also to sandwich completely the straight-back portion of the wind and continue to wind the winds to be always spiraling in the same direction:
4) Continue winds in this "pull back wire after each row style" until your length of magnetic wire is used up. You can skip a few winds each row too so that the coils will eventually be somewhat cone-shaped:
If destired, stainless steel trolling wire, like used in deep water fishing, can be wrapped around entire coil in "eggshell" fashion to have a very strong finished coil.
