I've found it quite feasible to use epoxy for bonding-on loose tenon rings. I
use virtually any reputable brand of fast-setting ("5-minute") epoxy (which
dries less rigid than slow-setting epoxy), and to make the final product even
softer, I frequently mix in fine grenadilla powder (as if making putty for
filling cracks and holes in the wood). Such a mixture will never get completely
hard, and is flexible enough to hold the ring without cracking (itself or the
wood of the tenon). I can't figure out why some of the repair techs who have
written about this are so adamant against using epoxy in this fashion, but I
would welcome their responses, as I'm willing to learn! Also, one can use the
gel-type (thick) cyanoacrylate glue ("superglue"), which when dry is somewhat
granular but not particularly hard. Neither of these glues, properly applied,
should cause damage to the instrument.
