Beware of the very high voltages between the strands.
Stefan mentioned up to 30kV loading coil
voltage, I guess even a fraction of this voltage will cause arcing between the
strands
In addition the high stray capacitance will
reduce the Q.

All vlf men
Instead of winding miles of single strand
insulated wire to achive the required inductance, use instead insulated multi
strand wire and series the strands, normally the individual strands have
coloured insulation and convenient to connect in series.
also
gather up all the ferrite cores you can find put
into a suitable container and insert into coil.
The above idea might save some coil winding
time.
another thouight while I am
composing
Litz wire.
Get hold of some old Decca coils ( I have a
couple) find the beginning and end and do the same as above, this however is
more difficult although individually insulated they are all the same colour,
but with a meter to identify each strand it can be done
