I made a custom port for a speaker box about two years ago in a similar
fashion. I made a insert out of Styrofoam and covered it with poly
sheeting. I
then wrapped the form with 1" wide fiberglass strips in a cross weave pattern.
When the entire unit was built up to where I needed it I simple poured some
Acetone into the center cavity dissolving the foam insert then removed the poly
and finished the port off. I do not see why this would not work for a
secondary
coil as well.
