I have a homemade coil winder I use to make my own custom transformers, coils, and solenoids that I use in my projects like this auto loading coil for a coil gun, or my first coil gun where I made the step up transformer as well as the propulsion coil.
As a green project this one saves energy in the making of wire and other components as well as recycling, one of the biggest savings is to your pocket book.
Step 1: Locating the Magnetic Wire
The yoke ring coils as indicated in the second photo with the yellow arrows, the yoke ring coils consisting of 28 to 34 AWG wire are in the front and the back of the yoke.
The lacquered yoke coils wrapping the yokes ferrite cores indicated by the red arrow in the second photo are too hard to salvage for reuse as magnetic wire, however they bring as much as $2.50 a pound cleaned copper.
The picture tube coil indicated by the yellow arrow in the third photo, on the back of the picture tube can be wrapped in electrical tape, foil wrap, and shrink tube. The magnetic wire in this coil can be 24 to 34 AWG.
