I'm going to make some wet lay moulds by hand using the EG160 tooling gel, EL160 resin and 450g carbon. I wanted to bag the moulds over night while the resin cures but want to know if regulating the vacuum is necessary? Does anyone have experience of using a regulator with hand laminating?
These moulds will be used to make parts in an autoclave. Obviously, tooling prepreg is available but the original part can't really be exposed to heat or pressure.

...I'll also make a mould using powder bound chopped strand mat and use it alongside the carbon mould to see how the fibre glass performs. It would be convenient if it works as it is easier to laminate with. Not sure CSM is the way to go on some of the larger moulds but might be ok for the smaller, flimsy motorcycle panels that I make.
