I would like to respond in this manner:
Mark,
Jim gave you the same answer I would have (stress points). I've see it happen.
Dick,
The answer to your question is yes! It's the way of splicing flexible cable to solids inside the wing. This method is used by a lot of expert flyers and my flying club has a few.
Andrew,
When the epoxy is applied, it's only put on the copper wrapping to insure it does not unwind and at the same time it's easier on the fingers when connecting the flying lines. Another method is to use heat shrink up to the eyelet which holds everything together. As you said, the AMA states the same way. I have seen a new set of lines right out of the box snap where the lines were crimped. I cannot understand why they would still make them that way. That is the reason a lot of flyers including myself make up our own lines.
As I said before, everybody has their own way of accomplishing the same thing, but when I see planes lost because of a failure, and I am doing the same thing as that flyer, I take that as a sign to find a better way of doing it, and at the same time pass the information along to other flyers. That's what I like about this forum. I hate to say it, but sometimes we learn from other peoples misfortunes and our own.
Regards to all,
Ron
