[TowerTalk] Easy removal of Heat Shrink Tubing

[Ian White]

As Roger says - it's easier to do than to explain.

In this context, "relatively clean" is just fine. Although the adhering
hot-melt adhesive doesn't look pretty, that isn't a problem. Think of it as
the primer coating for recycling the same connector with a new piece of
adhesive heat-shrink sleeving.

I have been able to recycle many connectors in this way... and it's all
thanks to the excellent sealing properties of adhesive heat-shrink tubing.

If the connection is cool or cold, this approach works better than warm or
hot.
Room temp works well, but may leave more residue.

There is a bit of a learning curve.  Some pick it up right away while
others, not so much.
Using a sharp knife, or box cutter with the blade extended just enough to
cut through the heat shrink.
Make a single cut  lengthwise from one end to the other of the heat shrink.
A second cut on the other side works well, but it's another chance to cut
into the coax jacket.  The cut does not need to go all the way through the
heat shrink

Using a pair of pliers, channel locks / slip joint pliers grab the heat
shrink at or close to the cut with the other jaw of the pliers about one
third of the way around the coax and pinch the heat shrink.  If you go too
far it will pinch the coax. That should pull a section away from the coax
jacket Repeat on each side of the cut along the length of the seat shrink.

Doing takes less time than explaining.

If the connection is cool, the heat shrink adhesive "usually" breaks away
from the connector, leaving the connector relatively clean.
  http://www.rogerhalstead.com/ham_files/connectors.htm  The splice shown in
the bottom right side photo shows a N-Type connector splice after the
flooded (adhesive lined) heat shrink has been removed. Some residual glue is
visible on the coax jacket but the connectors are relatively clean
