Hi DHG

Would you mind giving some advice on the construction of your
CW. I am keen to start.

I have never come across foam board here in South Africa even while searching for blue foam. (i do have blue foam now)

What could I use in place of the foam board in the construction ?
I could laminate some balsa or lite ply onto the blue foam or I could just use ply for the crutch etc - What do you think ?

thanks
Tim
