Thanks, Paul. I'll try to keep my eyes open for questions to which I may be
able to contribute. This one happens to lie right in the heart of what I
researched and studied when I was materials editor at _American Machinist_.

I also welcome your participation here.

I ran across a reference to anodizing causing weakness in AL and I can't
seem to find it again. I haven't found a narrow enough Google search to
be useful. Can you help?
