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.
