Step 1: Meterials
Electric Drill and drill bits
CD (or two)
Your own Spool of wire
Step 2: Cutting the Plastic
2 1/4"x 2 1/4" square. So cut your plastic 1/4" bigger than you want your coil. After you have cut your desired size, make another one that matches.
Step 3: The Nail and the Drill
Put your two pieces of plastic you cut on top of eachother, hold them or tape them down tightly. Then, find the center of your plastic pieces and put a nice hole through both of em'
The following picture will be the end result. (They don't have to be perfect, mine sure arent)
Step 4: The K'nex Spool Holder
Basically what your trying to make is a device that will hold your spool in place and let it unwind freely while your operating the drill.
The steps will be explained in the pictures...
Step 5: Preparing for the Wrapping
First, put the nail through the two plastic pieces you made earlier. Now here comes the complicated part (Pt.I)
When you put the nail into the claws of the drill, the claws and the head of the nail will act as stoppers for the plastic sheets, so the closer the claws are to the head of the nail, the thinner the coil will be, and the further the claws are from the head of the nail, the wider your coil will be. The space between the plastic sheets will be where the coil is wound. The coil will push the plastic sheets ourward until the claws of the drill and the head of the nail stop them, thus, determining the width of the coil. Got all That? maybe the pictures will help clarify.
When you finally decipher how to do and understand this, you are ready for winding.
Step 6: Winding the Coil
First, Tape the begninning of the wire (the lead) to the outsde of the plastic sheet. Then (depending on the way your turning), wrap the coil around the nail by hand a few times to get it started.
Once you have done that, pull the trigger of the drill slowly at first, make sure its wrapping. Then once you get it going you can pick up some speed.
Get to a comfortable speed and then keep that speed as constant as possible. Be sure to keep an eye on the proccess at all times, just incase something goes wrong.
Step 7: The Second Hard Part....
First get 3 or more pieces of tape at the ready, make sure they are longer than the coil.
Set the plastic pieces and nail (with the coil between them) on the ground so the point of the nail is sticking up.
Next, take the first sheet of plastic off Carefully!!! After that take 2 pieces of tape and put them on the coil so it doesnt fall apart.
Next, take the nail out of the coil and sheet of plastic carefully! You now should have your coil on one sheet of plastic with the leads taped to it.
Carefully untape the leads and let the plastic sheet fall off, hold the edges of the coil together to it doesnt fall apart, then tape the coil all up so nothing comes apart.
You may now change your underwear.
Step 8: Finishing the Coil
I have found it easies to first burn the enamel off with your lighter, simply put the wire in the flame and you shall see the enamel burning off.
But wait..thats not all, after you have burned off the enamel you will see that your leads have changed to a dark grey color, also not good for the current. To Fix this simply take a small piece of sandpaper and sand off the leads. your end result should emit a color of bright looking copper. Check the pic for a refrence.
