There was an article in this month's issue of Epoxyworks sent out by
Gougeon Bros. about adhesion of epoxy to various metals.
I don't have the article in front of me but I seem to remember that
Aluminum had the lowest adhesion strength of all the metals tested.
You can contact them and they will send a free subscription to you (I
think) if you don't get it already.
My guess is that epoxy would not work for this because of the expansion
of the metal and the oxide problem mentioned. I could be wrong.

Awhile back, there was a thread concerning stitch-n-glue using aluminum
rather than plywood. Although I do not believe it could be a high enough
quality solution to boat building, having a hard time believing in the
reliability of the epoxy bond and believing that welding is just as easy if
not easier, it is an interesting topic that I'd like to read about.

Meindert, and maybe others (?), mentioned knowing of aluminum/epoxy projects
going on. Does anybody have a link on the web that I can go check out? The
only link I had before is long gone, or at least I can't find it ...anyone?
Have you seen any of this on the web?

Thanks,
Brian
