Zfennell: Are you saying I should apply breather on the base side? I have wondered if breather on the base would allow better flow on the base since I am not sure if air is being trapped when the board is vacuumed to the table in rocker and concave. .
BWD said it first.
for the most part, everything in the bag is at the same pressure. (core, glass, resin, air film, breather etc) there is relatively little flow associated with the vacuum pump to move excess material.
the breather provides a way to 'press' the glass up against the core while moving excess epoxy and air to the opposite side of your release film.
if the pot life of your resin is sufficient you can degass the resin with vacuum before laminating.
use a foam roller or squeegee ( no brushes) to apply resin.
move in one direction only to minimise foaming in the cloth.
its both art and science that i have yet to master, so i cling to the few things that work for me.
i'm still sure everything can work with the right recipe.
