I've been asked to fix a broken table leg. It is ~ 3/4" in diameter and the break is a diagonal one. Normally I would bore a hole in the center of each piece and glue a dowel to bridge the break. Because of the diagonal nature of the break, I'll only be able to estimate the center and the likelihood of hitting exact center in both pieces is nil. I was thinking about making the hole over sized, insert the dowel, fill the overdrilled area with epoxy and then visually align and secure the leg while the epoxy sets.
Any other suggestions are most welcome.
