I pulled a vacuum on the mold this morning. As expected, it was not nearly air tight.
In fact, you could hear air being sucked right through the foam core.
There is no sense in proceeding with that plan.
I'm not really sure what I'll do now, but at the moment I'm considering stripping the mold, painting the inside with some resin to seal it and proceeding with a vacuum bagging solution.
I keep reminding myself that this stage of the build is a lot of testing and familiarization. No harm, no foul and nothing much lost except some time and a small investment in materials.
Still doesn't make for a happy day.
