Brent,

Yes, from what I understand this is correct but that is my problem, I don't
have a calculator to model this design to verify the parameters.  I could do
as Jason has suggested and just build to "spec" but I don't know if a
complete material spec has been provided.  I am enquiring as to this.  I
would however still like to understand the design, especially when the
designer has come to us to help him understand and verify the design.

Thanks to all for the input - keep it coming.

John
