I have several of those mast sections and the bottom of the next upper section
is smooth. That is, the splines from the lower section do NOT engae matching
splines above them. See

for a photo of the spline piece separate from the fiberglass section. This
piece enters the next section and can rotate freely, given enough torque on the
pieces.
