There's also one on the Belgium game:viewtopic.php?f=10&t=46015&hilit=Dampf
Hope you enjoy Chain of Command, the Lardies run an excellent forum on the web that can answer all questions and provide many useful resources, but if I can help with anything, just pm me.
And welcome to Frothers. It's going through a quiet patch at present but it has some extremely helpful and knowledgeable people - although great care should be taken around the fringes of the Frothpot!
Edited: re aluminium, I go for 0.5mm as it's easier to cut (via the score and bend method). I've use 1mm but it takes ages to score properly - but useful for really large bases.
