(see http://alberg30.org/maintenance/Steering/RudderPost/rudderstock.png) If your rudder is anything like mine, I suspect you'll find that you've got two fiberglass sides, one of which is glassed to the rods/bolts, and foamed resin was poured in between. This foam was trimmed around the edges and sealed with some resin putty. On Calypso, this joint was about 1/4" wide, as I recall.
