Hatch template Starting the cut with the jigsaw blade
A template of the hatch cut out is made and traced onto
masking tape.
The cut is started by scoring on the line with a utility knife.
 Once scored, the jigsaw blade is used to cut through the
deck.
Making the cut with a jig saw
Foam gasket applied
A jigsaw makes the cut.  The cut is stopped periodically
to tape the hatch to the deck to minimize vibration and
possible chipping near the end of the cut.
After taping the hatch in place from the outside, a foam
gasket with an adhesive back is applied to the inside
hatch cover along the outer edge.  The interior of the
kayak deck and hatch cover has been covered with clear
shelf paper.  This will function as a release agent.
Black fillet
Hatch lip laminations
A fillet of thickened epoxy colored with graphite powder
has been applied to each side of the gasket.
Layers of 6 ounce fiberglass strips are laminated over
the fillets after they harden.
Completed hatch lips
Hatch lips epoxied in place
After the laminations harden, the hatch lips are trimmed
with a jigsaw, the edges are rounded over with a sanding
block and the foam has been scraped from the groove.  A
thicker gasket will be inserted into the groove after the lip
has been epoxied into place.
The hatch lips are epoxied into place.
