09.00hrs and the project is a go !!
First up fix an old Champagne box to base board. This has had one end chopped off and stands 36cm tall. The box will create a sturdy centre for the volcano plus creates an inside for something I have planned later on.
Cut roughly to 36cm high
Glued and screwed to baseboard.

Step two glue in skewers around the base to hold the polystyrene at the heart of the volcano.

Simple bbq skewers hold the polystyrene in place
As you can see in the following pictures as the volcano takes shape I have not been particularly careful in measuring pieces. Afterall you are not going to see this in the final pictures.


So my final picture of the day...a polystyrene clad box...

If I can brave the cold outside I might spend another hour in the shed whilst the missus watches Mr Selfridge...
