Dave (and others following this thread),
The bracket holes holding the center board pivot and roller pins become elongated, I'm sure, because the pins rotate against the edge of the holes. My boat is probably an extreme case because by boat was on a mooring in Boston Harbor for the summer each of 10 sailing seasons, so there was a lot of rocking and rolling going on!
I am looking for feedback on this thought... In order to prevent the holes from elongating, I think it makes sense to restrict the pin from turning in the holes. The roller and keel will still be able to freely pivot around their respective pins. To restrict the pin from rotating in the hole, I am considering one of two options:
1) drilling one side of the new set of holes as a press fit, so the pin will be tapped into place with a hammer (The pin would be installed from the loose side, through the roller or center board, and then tapped into the opposite hole which is the press fit).
2) using 5200 marine adhesive instead of a press fit to secure one end of the pin.
This idea will also keep the assembly together when installing into the boat -- instead of using duct tape.
I appreciate any feedback given...thanks in advance!
