My idea is to lay some Carbon Fibre and use Fusion Fix spray around the outside top edges where the green arrows are pointing to secure it and then sealing the bag all the way around on the underside of the mould, will this work?

Don't try to seal the bag to the underside of the mould, this rarely works. Envelope bag the parts instead, much more reliable.

Hi and yes I am planning them up separately of course and the carbon fibre is going on the inside...

Thanks and yes but do you think it's okay to seal the bag just over the edge on the underside?

Thanks and yes but do you think it's okay to seal the bag just over the edge on the underside? No, make a bag as this is much easier than trying to seal against the mould's surface. Unless your mould is 100% defect free air is liable to seep through it and you will have no end of trouble getting a decent vacuum. Ask me how I know :-) What is your objection to using a complete bag? Edited 4 Years Ago by Steve Broad
