Take an empty CA bottle. THOROUGHLY CLEAN IT OUT WITH ACETONE. After it is clean, put your mixed epoxy in the bottle and attach a "Jet" CA tip. Now put the epoxy right at the seam.

I suggest diluting the epoxy ABOUT 5% by volume to allow passage through the small opening on the Jet tip AND to allow the epoxy to soak into the wood.. Be advised that the epoxy will take about 12 - 14 hours to set up and about 48 hours to dry because of the dilution.
