If you need to tunnel through a mountain or the centre of the earth then you are going to need some kind of Tunnelling Machine.
This is a resin kit from Ironclad Miniatures. This is a very clean casting.
There are not many parts and this dry run shows it was very easy to put together. So I went ahead and glued it together.
The first task was to wash the resin, to remove any remaining mould lubricant. Then I gave the model a white undercoat.
