Hi, I have a few questions about making a mould. If I were to make a mould for a part that's supposed to be a cover for something else, for example, a motorcycle swingarm, I assume the dimensions in the mould would have to be bigger than the actual part, and if so, how much bigger?  How does one determine how many layers of carbon fiber should be used in the product?

Yes sheet wax is great for this.  As mentioned above, we have recently released a tutorial showing just that technique.  You can find it here: Using Sheet Wax to Create Offset Moulds

In this video tutorial we explain why offset moulds are needed when making cover components and how to use sheet wax to create an offset mould. We then use our Epoxy Mould Making Starter Kit to make an offset fibreglass mould which in a follow-up tutorial we use to produce a carbon fibre frame protector/cover component.
