Simple post and 13 really good responses, that what makes SN, and its members, special.
Halekai brought up a good point, it appears that most cotter rings I have seen are very thin and are not robust enough to handle the clevis pin hole. Never thought about it before but sizing is critical.
Sounds like if the cotter is off good quality, the right size, and inspected each time you sail, then it minimizes the chances of failure. Rings are easier to handle but it seems that regular pins are more robust.
Thanks for the info...........
