The only way that I could see to build this is to make a bobbin that is just
over
the wire diameter high - 2 large flat steel plates lined with plastic sheet,
with a
suitable spacer in the middle, fix wire
in centre and wind. Remove top, (it might go ping) slide off the top varnish
as you go, remove bottom.
Just an idea
