It was really nice to see the canoe open-side-up for the first
time. After removing the forms, I immediately sanded off any sharp edges along the
top so the inside could be worked
inside was prepared by using a paint scraper to knock off most of the
glue. The scraper blades was rounded and kept sharp with an
occasional few strokes of a file.
wrapped around rolled-up
magazines did a nice job of smoothing the
interior. Sandpaper around a 5" piece of pool noodle worked
well too, although softer. Most of the work was with 60 grit sandpaper, and 100 grit
to finish it.
The fiberglassing went very smoothly, thanks to advice not to attempt wrapping the cloth around the inside of the stems. I epoxied
the cloth right up the sides of the stems, and later applied a small
fillet so the stems looked relatively smooth and clean.
sticks maintained the proper beam until fully-cured epoxy is
on both sides of the wood.
Only one filler epoxy coat on
top of the wet-out coat, so the interior has a non-skid weave pattern
construction note: Next canoe I will probably put filler coats to
achieve a smooth finish -- I think it might look better.]
Gunnels were scarf-joined before
gluing them to the boat. A jig holds the gunnel pieces perfectly
straight while the epoxy cures.
The inner and outer gunnels are both
5/8" wide ash wood. The underside of the gunnels taper from 3/4"
where attached to hull to 5/8" on the outer edge, so that water will
tend to pour off when the canoe is turned upside down.
Gluing the gunnels was achieved
with two people, as the 16 foot long pieces were unwieldy to
handle alone. After checking for a good dry fit, the gunnels were
buttered with epoxy thickened with silica dust, and a little sanding dust
silicon bronze) and clamps hold the gunnels in place as the epoxy cures.
These screw heads are covered by the outer gunnels.
I wanted small decks to keep the boat lightweight, but also wanted it to be a
good handle-hold and have a feature that allowed a painter to be attached.
1/2 inch hole near the point of the deck will allow rope attachment and
provide a drain hole when the canoe is upside down.
The underside where the deck, gunnels
and stem intersect received a small fillet to round it off and allow

can never have too many clamps when gluing the external gunnels! The
gunnels are also screwed in place with 1 1/4" #8 silicon bronze screws
from the inside.
The seat frames and center thwart received two coats of epoxy and a few
coats of varnish. I wasn't sure how strong the seats would be,
so the underside of the seat frames also received a layer of fiberglass tape
before the varnish.
Black one-inch webbing is my choice
for the seat.
This is my ninth epoxy-sheathed boat,
and I had my first allergic reaction to
epoxy the day after sanding some green epoxy on the gunnels and decks.
Very scary. I woke up with a hive-like rash over most of my
torso. Later in the day, the rash extended to my arms and legs.
I believe it was due to breathing in dust from uncured epoxy. I
normally wear a dust mask and try to avoid sanding green epoxy, but cold
weather had slowed the curing down so much. I'll be more careful now!
A 10' by 20' plastic painter's ground cloth hung over the canoe keeps most
dust specks off while the varnish is wet. The plastic is draped over
ropes and secured with masking tape. Plenty of lights.
Prior to varnishing, the entire
garage was cleaned by opening the door and blasting everything with a leaf
blower. Later, the floor was mopped.
