Here are two photos of my qick test on the locking
mechanism.
the tube is - by modest torque - expanded by 1/2 to 3/4
of a millimetre in diameter, although the aluminium
tube is quite rigid. Shoud do even better with the
laminated paper tube.
In case it doen't prove practical Garys plugs will
help.

The outside of each of the segments will be padded with
felt or rubber for proper friction on the inner of the
intermediate tube. (See drawing posted earlier)
