Here’s a yacht with some woodwork being created and installed.
Next are a few shots of templates created to build parts. In this case, arches for the stairways from galley to bridge and bridge to flybridge. The existing door will eventually be removed and a wood jamb with 3″ radius corners installed. These arches will have 3″ radius corners through the full curve(s).
Here are some photos of the corners being milled for the arch from galley to bridge- it’s a double curve, sort of an S shape.
