Making the mould...
And this is where it gets scary - making a mould from my lovingly-crafted master. I have stuck the masters to a piece of plastic card; my assumption is that I want a flat surface so that when I have poured the resin, I can run a blade across the top while it's still wet to ensure I have a flat bottom and minimal sanding after removal. I hope.
I popped the plastic card into a lego frame, and filled the gaps around the edge with wax. Then sprayed with mould release.
And mix and pour the RTV101 rubber from Tiranti. I am slightly worried about the number of bubbles surfacing, but I have knocked, tapped and jogged it as much as I can to try to get them all to surface. I will pop it out of the mould tomorrow... watch this space :)
