I think should use a drill, preferably a cordless screwdriver / drill because they are quite slow and you can vary the speed.Put it to a drill that has a very slow rotation setting,then the rest is simple !
Put a small mark on the chuck with tape or paint so you can count the revolutions, if you need to know the number of turns.
Ideally you want to maintain a constant tension on the wire as it comes off the reel. You can do that by running the wire from the reel between 2 felt pads stuck to the jaws of a vice (you could use the soft part of velcro).
Step 1: You Will Need
A pare of scissors
A wire spool
As well as the wire!
Step 2: Unwind the Tape
This is the hardest part as well as the most boring!
The tape usually starts where the two wires go in or sometimes about 6 inches down.
If you want to keep the tape you could wrap it around a pencil or something.
Use the scissors to cut excess tape and the two main wires but DONT cut the magnet wire!!!
Step 3: Unwind the Copper
Do it however you want, put the wire over my knee and turned it and wrapped at around the spool.
Step 4: And Your Done
Now you got tons of wire to make transformers, electromagnets, coil guns, etc. whatever you want with it!
