Hi Dinoman,
To make sure everything all stays positive I think it's clear you've got a procedure in your mind that you want to follow and that's totally fine. In composites, I think we've all learned that there's usually several ways to achieve just about any task and each of us can only say what works for us.
From an Easy Composites perspective we tend to take things a little further and experiment with lots of different techniques so that we can provide added value to our customers (i.e. saving them from false starts) because we're less constrained in terms of resources, materials and expertise. We did do quite a bit of research (I'm talking hundreds of test panels) of vacuum bagging moulds for high temperature use and it didn't provide the benefits we were looking for (vacuum bagging doesn't eliminate the potential for air pockets between gel and reinforcement). Resin infusion - on the other hand - is a different story and resin infusing a mould does make a lot of sense and works well, however it's often impractical to do because you really need to be working on a solid pattern (either a splash part or tooling board) rather than an original with temporary barriers, etc.
I hope you the input from ourselves and other members useful, I'll be be interested to hear how you get on and of course be ready to learn something from your results.
All the best, Matt
