Creating the Mould...

Now the prototype is smooth enough to level it needs to be. (It doesnt need to be perfect as the wheel is going to be wrapped in carbon fibre.) we can create a mould from it, the slightly better way although a little more expensive is to use silicone.

You create a box frame, i use lego as it means you can take the box apart when the silicone has set easily, by placing kitchen film inbetween means its leak proof as well which is obviously very important.

the first half will take 36 hours to set, I will then cover it in vaseline as a release agent so when i do the 2nd half it will come apart and I can remove the prototype.
