or plastic)

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.
