I'd say that if the runner block holds-up, then they'll be OK.Best of luck to you all, hopefully your work will pay off. From my vantage point behind a computer in the frozen north, I just wonder what kind of compression load that can take (having seen a compression failure in the past).There are some very talented people in the crew working on it with other contributors including Ben Hall of Hall Spars who built the rig. We will not go out if it is unsafe as we were very lucky no one was hurt today and we don't want to push our luck. Those photos were just from the mocking up stage, there are about a dozen carbon fiber battens that will be held in place with shit ton of machine screws and some extremely strong epoxy given to us by Hall Spars. Then the outside of the joint will be wrapped in carbon fiber and epoxied.
