Seat and centreboard case

The seat will become the top of the centreboard case, both have been laminated from left-over ply. The inner faces of the centreboard case have been given a coat of epoxy and glass to aid strength and resistance to abrasion.

Centreboard top

Using a router a slot has been cut in some Iroko to make up the top of the Centreboard. The top has been fitted using epoxy thickened with Collidal Silica to give a very strong bond.

Epoxy and glass coating the rudder and centreboard

The centreboard and rudder blade have been epoxy and glass coated to protect the cedar from water ingress. Here one side has been done, the glass will be trimmed back before tackling the second side. The glass cloth should increase the stiffness of the centreboard and help with the inevitable knocks in use.

Cedar-strip centreboard and rudder blade

An attractive centreboard and rudder blade have been made from strips of cedar that I have laminated into a board then cut to make the two underwater foils. These need some further sanding before a coat of glass cloth and epoxy is applied to add strength and protection. A final coat of varnish will be required for UV protection. Both the foils have been oversized after comments from another Pup builder who suggested the standard size is a little small leading to excess leeway.
