Caledonia Yawl – Chapter 8: Getting ready for paint

There is a lot of prep work to get ready for undercoat. We are also doing a lot of sanding and filling, and epoxy coating of plywood end grain.

Before assembling the centerboard trunk and the rudder head, the interior surfaces are coated with graphite filled epoxy. This negates the need to paint these areas in the future, and protects against chafe in high wear areas. Note that the channel for the rudder control line is also coated with graphite filled epoxy.

We weight the centerboard by adding a lead disk. We cut a hole of the correct size near the bottom of the centerboard. We chamfer the edges of the hole and insert bronze ring nails to stabilize the lead plug. We then cast the plug in place.

We have painted the under deck areas, and the underside of the decks themselves, so we could glue and fasten the decks down.

Now that the decks are in place we are fitting the trim along the deck edge, and a bit more around the motor well. We are also working on rigging items to fill in the time gaps while we wait for something to cure.

After shaping the rudder blade and centerboard and adding the lead plug, we apply Dynel cloth saturated with epoxy to the leading edge and tip of each of these two parts. Then it’s time to fill and fair them before we are ready to apply paint.
