Undercutting

 

This is a little acanthus scroll trailboard for a Victorian launch restoration, currently at the tweak and finish stage. The turn at the bow end is a little too oval, but otherwise it’s coming together nicely. The thing that really makes a deep relief like this ‘pop’ is to undercut it.  Undercutting is done to take the sides of the design out of sight. It is important that this is not overdone or the edges will be weakened. It is also important the back of the carving keeps in contact with the hull; if it is raised it will be susceptible to  breaking off when the carving gets knocked. The thing to bear in mind is to avoid pockets for water to collect in.

 

The first picture shows a vertical view but even here some of the sides of the carving are visible.

Whereas this image is only slightly off-vertical and the sides are clear to see.
