Measured C and calculated L of thick and thin insulated coil winding wires ... questions

[Polymer]

Thanks, Wanted to try the coil calculator. You posted about 9inch mean diameter. Calculator asks for inner radius(diameter). If you can, what is the inner diameter?

Mean inner diameter around 21cm. Hope you get that calculator to work.

Using the GeoTech coil calculator (as I posted above).
Inner Radius - 105mm
#turn = 20

Wire thickness= 2.7mm (Yellow coil)
Inductance = 173uH
Wire thickness = 1.0mm (Blue)
Inductance = 219uH

These are right in the pall park of your measurements.
And show the effect of different wire diameter
