You can still get a nice workable coil with a 6 inch diameter
coil form and #24 wire (if that is what's available then might as
well use it up). Just reduce the aspect ratio some, and wind on
the wire. If the materials are in stock then you would have a
nice working secondary, even if not a "perfect" secondary,
without having any substantial investment in new construction
materials. Learning to wind and assemble a "perfect" secondary
takes a few attempts for many people anyway. Practice makes

I am a firm believer that when nuts comes to bolts (of lightning) 
then it is best to wind on wire as opposed to not winding on
wire. This counts double if it's coil form and wire already in
stock; these materials do no good sitting on the shelf or on the
