I started with two large blocks of polystyrene because one wasn't wide enough for the crater. I stuck the two of them together taking the precaution of pushing half a dozen cocktail sticks into the material to hold them together while the glue dried.
Before I permanently fixed the two pieces together, I used a plate to mark out the crater on the top of the volcano island. Using a long bladed knife I cut into material - I went down about 6 inches. Its easier to cut out the crater before sticking the two parts together.
I used PVA to stick the two parts together, which was a mistake, I should have used a hot glue gun as it slowed me down.
The basic shape of the volcano. I've trimmed off some of the edges to give the impression of height and then stuck offcuts onto the sides of the volcano to give it more bulk. At this stage, I've also given the crater a good coat of PVA and sprinkled sand and gravel in there to dry. You can also see that I've made a start on the trail running up the side of the volcano.
I needed to add another offcut of polystyrene onto the side of the volcano to make sure the trail isn't too steep. You do not want you soldiers to fall off do you?
I left one side of the volcano quite sheer.
I stuck another offcut onto the side to create a ledge.

Next I gave the whole thing a coat of powder wall filler and PVA mix. When this was still wet I scattered sand and gravel over the whole piece. I then painted the volcano dark grey and highlighted it with white.
Another view of the progress so far.
This is trail side of the volcano. When I finish this off I'll pick out the trail with some brown and static grass. I'll also add some palm trees or scrubs to give the whole thing a bit of colour.
I'll post up some finished pictures of the volcano in June.
The other thing I plan to do is to add some red, orange and yellow into the bottom of the crater to simulate lava.
