A good method is to run 4 or 6 strips of double sided "scotch" tape along
the length of the coil form. The end of the windings temporarily can be
held in place with tape. Once you have coated the secondary winding with
several coats of whatever is compatible with acrylic, the coating will hold
the ends of the winding in place and you can remove the tape.
Another other method is to spiral the winding to the edge of the coil form
where you run it through a small hole drilled 45 degrees through the very
edge of the form. This holds the wire very securely but doesn't penetrate
into the interior of the coil form.

I'm new to the tesla coil world and coil winding, I'm currently building a
coil using a 15kv nst. Anyway I fine on the contruction of everything other
than winding the secondary coil, I've obtained a 3"x27" piece of acrylic
which has a high sheen to it. Now I've never wound such a large coil, (the
largest was a loo roll tube when I was a kid for a antenna tuner.) Can you
suggest how to go about a fixing the wire for the first turn and how to keep
in place while winding, special as I'm doing this by hand. My own thoughts
to rough the acrylic up as to not have a slippery surface, and apply a light
varnish as I go which should go tacky and hold the wire.
Anyway thanks for any suggestions
