Side sheeting after trimming.
Another view of trimmed sheeting and stringers.
Transom glued to bulkhead 5
Push down and forward, increasing the angle as
you move forward.
Use the angle on the bulkheads to determine the
angle that you hold the plane.
When you are close with the plane, switch to fresh
80 grit on your sanding block.
Match the angle of the bulkheads. Also, lightly
sand half of the keel at the same time, so that the
bottom sheet lays flat on the structure. Do not
change the shape of the keel, just match the angle.
The keel will have a slight “V” shape when you are
done.
Be very careful not to sand the keel too much,
or the bottom will not fit!
Sand the rear of bulkhead 5. Sand the stringers and
sides flush with the bulkhead.
Using 30 minute epoxy, glue the transom to the
back of bulkhead 5. Try to match the bottom “vee”,
and leave an equal overhang on the sides and top.
Clamp until dry.
Make a mark in the exact center of bulkheads 4 and
5. Make this mark on the edge, so that you know
how far to glue the sheeting.
Test fit the bottom sheeting in place. It should cover
exactly half of the keel. Also, sand a gradually
increasing bevel on the inside (center) edge, so that
both sheets will meet squarely.
Make sure the front is accurately aligned with the
center of the keel and that there is some overlap at
the rear.
When satisfied with the fit, make an alignment mark
on the bottom sheeting and the keel.
Cut about 8 pieces of wide tape, and set aside.
Mix about 1/2 ounce of 30 minute epoxy.
Using a small stick or acid brush, coat the stringers
and bulkheads where the bottom sheeting will
contact. Work quickly.
Also coat half of the keel.
Brush epoxy onto the first 6 inches of the front of
the sheet, to help the glue joint here.
Align your marks and put a couple of clamps along
the keel, clamping the sheeting firmly to the keel.
Check your center marks on bulkheads 4 and 5.
Wipe all excess glue off of the keel, as it will
interfere with the other side sheeting.
If everything looks good, start wrapping the wide
tape across the bottom sheeting.
