Carl Goldberg's 1938 Comet Clipper
The longerons
are over 36 inches long so unless you have 48 inch stock they will have
to be spliced. It is probably better to splice the upper
longerons
anyway as a good transition from straight at the
front to curved aft of the wing mount is easier to get that way.
The front section was sliced and then
glued on below the aft
section. Sanding will make everything good later.
A way to get a
good splice joint on the lower longerons. The hardwood block
serves as a holding tool and a backup so the balsa sticks won't bend as
they are pressed against the wheel sander.
The left hand is holding the balsa sticks against the hardwood block
while the right hand presses the block against the sanding disk.
The finished
ends, with the angle and the length
identical. Be careful to hold the hardwood block flat against
the
sanding disk table so the finshed
edges are perpendicular to the side
of the sticks.
A length of
aluminum angle is a good tool to ensure straight joins when splicing
longerons.
Plastic wrap
covers the aluminum angle to prevent sticking and with glue applied to
the joint the sticks are joined and clamped.
