every bulkhead. It should feather out
and lie precisely on the bearding line.
If not, trim until it does. Also check
that the top of each bulkhead at the
centerline is flush with the top of the
center keel. Since alignment is based
on the reference marks, slight errors
can occur. Sand or add shims until the
bulkheads and center keel surfaces are
flush (Figure 1-7).
Next, sand in the remaining bevels.
Check the hull’s fairness by laying a
1/8” square basswood batten against
the bulkheads at various locations
(Figure 1-8). Correct bumps and dips
by sanding or adding shims. This is
an important check, for manufactur-
ing or assembly errors can occur and
the hull planks must lie flat against
the bulkheads.
7. Installing the Stern Blocks
& Transom Framing
Port and starboard filler blocks butt
into
Bulkhead O and the center keel.
They support the stern frames and
provide more area on which to glue
hull planking (Figure 1-9). Follow the
plans when carving them.
8. Installing the Horn Timbers
Install the 1/8” square horn timbers
on the center keel per the plans. They
support the ends of hull planks at the
counter (Figure 1-10).
9. Covering the Mast Slots
Cut the pieces shown on Sheet 2 from
scrap wood, then glue to both sides of
the two mast slots in the center keel.
Make sure they are securely fastened,
because access to them is impossible
after the deck is laid. Notice the two
methods shown. If a flat piece is used,
cut a tenon in the bottom of the masts
to fit the slots (Stage 6, Step 2).
10. Installing the Waterway
The waterway in the fore deck is
3/32” thick. First, fit the plank
between the bulwark stanchion exten-
sions, then the other two inboard
planks. Note: The third (innermost)
plank has a slight bevel on its inboard
edge (Figur
e 1-11).
