Deck Beam on Foredeck: A view of
a a deck beam on the fore deck, just at the beginning of the
deckhouse. This project will replace ten deck beams and will replace
the ends of others. The filler pieces are notched into the deck beam
and run longitudinally, providing strength, stability, and strength
of the fore deck. Towards the edge of the deck, the shelf structure
of longitudinal timbers is visible. The shelf provides longitudinal
strength, resists compression, and is the seat for the deck beam
ends. The clamp timber can be seen protruding slightly higher than
the other shelf timbers. The deck beams are notched to lock over the
clamp. The deck beam structure is built of recycled yellow pine
timbers salvaged from old mills and barns. It is strong and seasoned,
and is not beginning its second career and century of service.

Rudder Bearing and Horn Timber: At
the stern, the horn timber rises up and aft from the stern post,
providing the centerline strength for the stern of the tug. Here is a
view of the bottom of the horn timber, where the rudder shaft
intersects with the horn timber through the rudder bearing. The steel
forging seen here is the overhauled lower rudder bearing, complete
with Monel nuts that have been cleaned. In the upper left corner is a
portion of the tail feather boards that are located on the sides of
the horn timber. The tail feather locks the horn timber in position,
passing the vertical stern post on both sides. It also provides the
landing for all framing aft. The planking will end at the horn timber
as will the internal ceiling planking. |

Apron and Stem Pieces: Here
at the vertical bow of the Luna are the stem timber (right)
and higher apron timber (left) which are sistered together with a
series of countersunk bolts, creating a massive white oak complex
that is 26 inches deep and 12 inches wide. The apron is higher
because its top portion will be fashioned into a riding bitt for
lines. The vertical notch carved into the side of the stem timber
will accommodate the ends of hull planking. The tar between the
timbers stops rot. |

Framing with Salt Stops: Here
is completed framing, with the horizontal salt stop
"shelves" in the void spaces. The frames are double sawn
from 6-inch thick timbers that reduce in depth from 12 to 8 inches at
the main deck. They are bolted together, and coated with linseed oil
to slow the drying process. The salt stops will form the base of salt
that will fill each frame spaced above them. |

Horn Timber Side View: Here is
the end of the horn timber, showing the rudder stock and bearing
assembly intersecting with it. The thin plywood pattern for the
massive 14-inch rim timber of the eliptical stern can be seen
resting on the aft end of the horn timber and tail feather boards
outboard of them. The pattern is checked and adjusted to guide the
critical cutting of the rim timber. |
