Hi. I've read elsewhere that a mould should typically be about 3 times the thickness of the part to be laid up in it.
Is this always the case or just moulds made using polyester resin? Would an epoxy/roving mould need to be so thick?

So when you say corners do you mean inside or outside?
I'm thinking I will have to split the mould along that top edge across the width anyway so that might make the layup easier.
I'll probably use the slow setting epoxy. I'm in no hurry and hate being against the clock!
The time factor is what concerns me the most I think. You can't just make this up as you go along and see how it goes.
