Telescopic aerial repair...

I was given a portable receiver with a damaged telescopic aerial, the
set had been dropped and one section of the aerial had become slightly
buckled. and wouldn\'t telescope inwards. I first thought it would have
to be either left protruding or written off and replaced with the
nearest substitute I could find, but later examinatuion suggested it
might be repairable.

The first step was to remove the finial; this had been screwed on
tightly and locked with some sort of compound. By gripping the finial
in a collet chuck on a lathe and the top section of the rod with a
strong pair of water pump pliers, I was able to revolve the chuck by
hand and unscrew the finial.

The next step was to find a collet that was a reasonable fit over the
damaged section. By screwing up and unscrewing the chuck ring I was
able to make the collet gently pinch the damaged area down onto the next
rod inside it - gradually working my way along and back until all the
creases had been removed.

Although the result didn\'t look perfect, it slid in and out easily
enough. It just remained to screw the finial back on, with a dab of
varnish in its threads.

Job done - cost nil.

Neat! Congratulations on the \"impossible\" repair.
I suppose many of us have kinked telescoping antennas.
I never heard of one being repaired before - replaced yes,
un-kinked no. Thanks for posting that. :)
