2. Carefully remove the battery and wrap the ends around the coil 2-3 times to hold the coil
together with both ends extending perpendicular to the coil as shown below. The ends
should be aligned in a straight line to form a good axle. This step requires a lot of accuracy
because the balance of the coil is extremely important.
3. Strip off the insulation completely at one end and only half of it at the other. This step is
very important, try to be very accurate.
The following picture shows how to remove the insulation using the knife. Do not scratch
the table - put a piece of cardboard or similar material on it. Hold the coil in vertical position
with one of the ends lying on the surface and remove the insulation by moving the knife in
the direction shown with the arrow. Hold the blade of the knife in vertical position. You will
need to rotate the coil slightly in both clockwise and counterclockwise directions to remove
half of insulation, and rotate the coil 360° to remove the insulation completely from the
other end. Apply only a slight pressure or you may cut the wire end off.
