This mast is smooth all the way, no cams, locks, etc. The tubes must
be "slightly" tapered such that as you pull one out of the other it locks
in place by sheer friction.

After stuffing myself with a near-terminally fattening ice cream, I
realized that we may be talking about two different types of masts.
I'm thinking of a telescoping mast, where each smaller section fits
inside a somewhat larger diameter section. Kinda like a telescoping
metal whip antenna (i.e. rabbit ears). However, there are also masts
made of equal diameter tubing, with some sort of coupler at the ends.
Your initial posting clearly said "telescoping" but I'm wondering how
one makes a self supporting telescoping mast without an internal or
external locking mechanism.

Which type to you have?
