No experience with loose tenons, but I'm thinking the tempered

Even if it did take glue well, with no grain to span the joint, I doubt
you'd ever gain much strength. If I were going to use anything but
wood for the tenons. it'd probably be scuffed-up lexan or sandblasted
aluminum, though I don't ever see myself trying that. Actually, I have
a Beadlock unit for just such situations and it performs very well.
