looks like a solid job personally i would have also put some pvc/fiblerglass tubing the right diameter inside one side of the pole glue/epoxy in place to create a male part to side the other piece onto more glue/epoxy then as he done.i would say it would be solid enough for a pole rod that's slide in and out but for casting comps and pendulium casting i would take care till ive done 10 or 20 casts.
