I have tried this but it is not a nice as a copper pipe or strap
primary. First, removing or adding turns by taking off and adding
in loops of wire creates a problem with off-axis inductance which
lowers the tank circuit efficiency. You can cut off and splice on
sections of wire to get around problem #1, but it looks bad and
the splices have a tendency to leak corona and are prone to
flashovers on the primary coil.
I don't think any reasonably priced wire is going to offer the
efficiency, ease of use, and good looks of a well constructed
copper pipe or strap primary coil.
