However, I would not hesitate to use carefully mixed (make sure the
proportions are correct), thoroughly cured (give it a day in a warm
environment) and cleaned (swab it with alcohol) epoxy in small
quantities. I have used metal-filled epoxy to repair broken wooden
combs. Epoxy has the advantages of filling large gaps in a glue
joint, practically no shrinkage, very high cured strength, and
machinability. It will replicate the smallest details of a mold.
It is essential to the technician's bag of adhesive & molding tricks.
