Anyone have suggestions on a method I might try to "twist" and collapse
some sections of my telescoping fiberglass mast? I put it up several days
ago with perhaps a bit too much "vigor" in making sure it would not
collapse on its own and now that I want to stow it away there are a couple
of sections I can not unlock. My grip is good, but the sections are really
tight. I hate to use something mechanical for fear of cracking the
fiberglass and I hate to use a lubricant since the locking requires
friction.

Let me guess. You extended the pole when the air temperature was cold
and are now trying to collapse it when the air temperature is hot? The
coefficient of thermal expansion is about the same as glass or
1.1x10^-5 inch/inch/F which is enough to expand the inner tubing into
the outer sleeve almost permanently. After a few field days of having
exactly the same problem, I sorta learned my lesson.

The easiest is to wait until it cools down at night. You can also
splash cold water on the joints, which might help. If you want to
prevent the problem in the future, I found that ordinary Ivory soap
smeared on the joint, makes a decent lube that will not cause
premature collapse. If you apply too much, just wash it off.

Also, do NOT beat on the ends in an attempt to release the seized
joint. The twist type telescoping locks will just lock even harder.

If brute force is your forte, you might try a rubber pipe strap wrench
as used to remove an automobile spin on oil filter. Wrap the strap
around a few times and put something under the gripper teeth to
distribute the force. I've never tried this but it seems like it
might work.

Also, make sure you're turning in the correct direction. I did that
once with a window washer pole with predictable results and
embarrassment.
