I like to use aluminum in segmenting. I HAVE had problems with the glue not holding well between the metal and wood, even after scuffing the metal up a bit. Especially during drilling. I think the shear strength of the CA glue bond isn't the best. Once sealed with a finish, though, I've not had any problems with joints coming apart.
I prefer to use roof flashing material. Its a bit thicker than soda can, but still not difficult to turn. I usually find that persistence pays off when working with aluminum. Having to "re-glue" a couple of joints that come apart is normally worth it for the results. Here's a pen I posted a couple of weeks ago that gave me some problems, but, as I mentioned, was worth it in the end. This one came apart at least 10 times during drilling and turning.
