How to couple two poles to make a quick extension pole? (wood, metal,

Problem: Couple/join 2-3/4" dia 5' long poles to make a 10' extension
pole that will not twist slip but which may easily pull apart?

Fewest parts, easy and inexpensive to manufacture.

Ideas??

Plastic plumbing pipe. Shove the sections into couplings and they'll stay
together - good enough to hook a clothesline back over the pulley. Plus
you can easily glue/bolt/clamp something to a coupling and stick that on
the end.

Gotta twist off a hard to remove floodlight, etc.

Swage one pipe so they slide together, "Wishbone" style pin lock
like used on swimming pool vacuum poles.

But I use a standard twist-to-lock painters roller style pole to
change light bulbs all the time. If you have to put enough torque on
the pole that overrides the locking tension on the pole sections,
you've got bigger problems with either the lamps or the sockets.

First, you have to define the REAL problem, then you can solve it.

Cheap imported aluminum base lamps and cheap aluminum shell sockets
are always bad separately, but when they are combined and you add any
moisture at all and allow time for them to corrode to each other...

Buy the better brass or nickel plated brass based lamps, and brass
shell sockets. Then they'll come apart without a big fight.

I've been having great luck with a little tube of spark-plug-wire goop
from the autoparts store.

Dielectric grease, that's it.
