Hull Construction |
|
  
Apply
Slow CA to the bevel on the stem, the first inch of the deck
edge, and the entire edge of the breasthook. Carefully align the
stem with the pencil marks on the sheeting and press it into
place. Hold it in position until the Slow CA cures (about 20
seconds).
Bend the
sheeting into contact with the entire side of the hull. Make
pencil marks on the sheeting to indicate the edges of the deck
and chine logs. Then, carefully cut the excess wood off about
1/2" outside of the pencil marks, as shown.
Working a
short section at a time (about two to three inches), use Slow CA
to bond the sheeting to the deck edge, frames, chine logs and
transom, as shown.
After the sheeting is glued
in place, use an X-Acto® knife to trim the sheeting flush with
the bottom of the chine logs and the rear edge of the transom.
Trim the top of the sheeting about 1/4" above the top edge of
the deck, as shown.

Roger's Notes:
The
sheeting is trimmed above the deck edge to provide a dam that
will prevent excess resin from fouling the deck when the hull is
fiber glassed. You can leave this extra sheeting if you
wish. I sanded mine flush. Remember that IF you do
this, you need to take precautions to prevent excess resin from
fouling the deck when the hull is fiber glassed.

Side Planking
Turn the
two sheets over. Open the joint and run a bead of Slow CA onto
the edge of one sheet, as shown. Then, close the joint and lay
the sheets on your building board. Immediately rub the joint
flat along its entire length with your fingers.
After the Slow
CA cures (about 20 seconds), remove the masking tape. Use a
sanding block to sand the joint flush on
both
sides.
Roger's Notes:
The object of Step #95 is to accurately locate the stem on the
balsa sheeting, so that when it is glued to the sheeting, the
sheeting will curve across and cover the entire side of the
hull.
Center the side of the
hull on the joined balsa sheets so that the deck edge, near the
transom, is in contact with the sheeting. Keeping the deck edge
and chine logs in contact with the sheets,
roll the hull forward
onto the stem, as shown. Hold the stem against the sheeting and
draw a pencil line on the sheeting to locate the position of the
front and top edge of the stem, as shown.
Roger's Notes:
If
the hull slips on the sheeting while rolling it forward, or if
the deck edge or chine logs roll off the edge of the sheets,
just re-position the hull on the sheets and try it again.
