I don't know how many times I have to say this but resistance is NOT the factor to watch in coil winding. You MUST pay attention to the inductance first and the overall circuit impedance next. The resistance is not relevant at all for making the field. The resistance will determine how much power you must pump into the tuned circuit to build the field.

It's all about that moment when metal that hasn't seen the light of day for generations frees itself from the soil and presents itself to me.

Do you have any test equipment? An oscilloscope, perhaps?
