I needed to make a mould of a 50 cal shell casing to make replicas, I’m in the UK so they are expense to get hold of here.

As I was making the mould I thought I would document the process so that others can learn how to do the process.

I will be making a very basic 2 part block mould out of RTV silicone rubber.

This is a mould for use on my Life Sized ED-209 Project, from Robocop check out the Facebook page

The shells were be used as set dressing when its complete but I have decided that actual shells will be better.
