I'm not sure you could get the pin tight enough to eliminate any movement in the fitting which, over time, would erode the fitting and / or the pin. I hope this discussion has not caused any concern among those still building. The use of multiple bolts in single sheer on the WAF are quite sufficient for safety as proven by the thousands of flight hours on that system. Granted, the single bolt in double sheer is a stronger system but not necessary for safety in our application. I'm sure that some governments have required that design as it is very easily accomplished with little or no weight gain. On the other hand I know of no one using 1/4 inch cables in the control system just because they are stronger. Adequate is adequate. If something has been flight tested and is safe, go with it.
