Default Coil Calculations?

Thanks Tom,
I went ahead and wound the new coil with the same amount(25)of turns
as the original and will go from there. Like you mentioned I think I
am over worrying it.
I have a Grid Dip meter I have been meaning to learn how to use so
maybe I will try and learn on this coil...

As for the inductance calculator,I have no idea why it never works for
me? Every time I have tried to use it,it gives me an error?

Hi Ken,
I am assuming that the new coil is going to be wound at the same pitch
as the original as the form its wound on has spiraled groves in it
that the wire sits in.

Hi Michael,
The coil is actually part of a trap on a 3 element tri-band beam that
handles full legal limit power.
so I am guessing that the slight change in wire(from 11 to 12
gauge)wont hurt anything.

Can any of you suggest a good book on coils,that includes theory,math
and all that good stuff?

I Appreciate all the help and Patience everyone
Thank You
