My coil will look similar to this...
These calculations are made using the method where each wire is laid directly on top the other. not in between the other wire.
If the bobbin is 4.5" OD for the first layer.
coil 1 is 148,433 turns,
The OD of that coil is 7.835",
approximately72.448Lb of bare copper,
and about 76.4lb with the coating,
73,033 meters,
24,721ohms,
138 layers.
if the OD is 7.835" when starting the second coil....
coil 2 is 101892 turns,
the OD of that coil is 10.125"
approximately 72.453lb of bare wire,
and 76.41lb with the coating.
73.039meters long, and 24,743ohms,
should be about 95 layers.
the rest is what ever is left on each spool. that will be added one coil at a time on top.
If we had 160lb of wire ( with insulation) we would have a total of 258,957 turns
241 layers.
153,178 meters,
51.850 ohms
151.95 lb of bare copper.
Just some notes to do with my Drawing...
