Making Moulds

Many times in your hobby-making life you will find that you need several copies of the same model. If you only need one or two copies, then sometimes it’s probably easier to just make them by hand. But if you need lots of copies, or the detail on the original is too difficult to reproduce manually, then you will probably need to make a mould from it and then cast it repeatedly.

These pages are an attempt to share my experiences and hopefully hopefull demystify the whole mould making process.

Firstly I will look at a couple of key items you’ll need – the moulding compound, release agents, and the casting material itself. And then I will explore the processes involved in making single-part and two-part moulds.
