You are on the right path.

Hell I am married and have a nine year old step-son. They hassle
me. This is my "relaxation"...
Placing baffles inside of the coil form will reduce the coil Q.
Using solvent based adhesives create an explosion hazard.
I have wound enough coils that I have made nearly every possible
mistake, including the use of internal baffles and solvent based
adhesives. I have had coils explode because they failed due to
dielectric weakness, and the adhesive used in construction left a
residual flammable vapor trapped in the coil form which ignited.
I feel I have made enough mistakes that I should be qualified to
instruct others (though I am still learning myself); I created
the COILBLD series of text/graphics files to provide very
specific instructions that detour around known pitfalls. End caps
(only), and epoxy or other non-solvent adhesives.
... If all else fails... Throw another megavolt across it!
