For winding Tesla secondary coils the
general consensus is to use |
|
|
number 22 AWG, or larger diameter, double
Formvar Magnet wire. Often |
|
|
surplus partial spools of odd wire sizes are
found, so I took time to |
|
|
post a more complete chart of AWG numbers
and fractional diameters |
|
|
than is usually available. All information above is approximate |
|
|
despite the decimal places. Wire diameter,
turns per inch, resistance, |
|
|
feet per pound, etc. all vary slightly from
one manufacturer to another. |
|
|
Insulation thicknesses will vary depending
upon type and the supplier. |
|
|
Turns per inch will also vary with the
quality of the winding. In |
|
|
practice, Tesla coil windings are not
perfect (nor do they need to be) |
|
|
so expect some slight variations from the
specification table above. |
