Hi all, 

I have been working on a project for a fair while now, and I'm starting to see light at the end of the tunnel. As you can see in the attached pictures I started out with an unflanged mould in sight of using a wet lay-up technique.

Due to wanting cosmetically perfect parts and after consultation from the EC staff I decided to go for resin infusion instead. 

I modified my moulds so there would be sufficient flange space by adding a frame and a high-gloss surface to ensure that I can pull 100% vac. 

I am just about ready to start my first infusion and would like a few tips.

The first mould I want to do is 70x40cm and approx. 7cm deep at its deepest point. I am planning to use 2 layers 200g carbon cloth and 2 layers of approx 150g e-glass. 

Is this a good combination and how much IN2 resin will I need based on the information?

There is breather material included in my starter pack and it is also mentioned in the instructions, yet not in the video. I assume I should be using it. 

One more question (i hope): Can the reinforcement be cut smaller than the edge of the mould, or does it have to be almost at the gum tape? 

I hope I've formulated myself correctly!

Thanks alot.

Fabian

Hi,

If your leak is too little to be noticed, what about wraping the whole mold in the vacuum bag? Then even if your mold has tiny cracks, the bag will enclose them.

If you do so, be careful with sharp edges on your mold that could damage the bag.

Good luck !
