Scored a nice Butz-Choquin for $20 on Ebay. Started cleaning it up a bit and voila! The tenon dislodged from the stem. The previous owner said it had been repaired before, but now I have a tenon that I need to affix back into the stem. My question is what works best? I've heard epoxy is best, and others have said just use superglue. Any suggestions?
