Over on FB, a builder has cut some fins with the grain that didn't go parallel with the root edge, or the leading edge, leaving a large area that is "pop fin" like. I'm can't find a tutorial that shows a comparison on how different fin grain alignments corresponds to fin failure points. If I were back in the states, I'd have the resources to do this myself, but here in China, I can't. Could someone make up a few sample fins cut to the same shape (say similar to the Der Red Max, or Goblin) with grain running parallel to the root edge, parallel to the leading edge, and one that is something in between, and then test them to destruction. If you're really ambitious, perhaps going to the point of redoing the test with papered fins, and sealed fins, and if you're super ambitious, using different glue methods (CA vs double glue vs epoxy).
