Tom and all,
That is quite contrary to my experience. The APP housings that I have
purchased (from both PowerWerks and West Mountain Radio) have dovetail
matings that need quite a bit of force to slide completely together, and
I lock them with a drop of SuperGlue. I never had one come apart, and
that includes the 3 of them that are in constant use on the workbench.
The ones in the hamshack are more permanent - they are seldom changed.
I have roll pins and use them only sometimes. If I use the roll pins, I
lock the pins in place with a drop of Superglue.
BTW - I just saw evidence that using the 'good' West Mountain crimper is
not the entire answer. The crimps this gentleman had made with that
tool had distorted the connector barrel and tongue severely such that
good contact was not made. When we discussed the problem, I found that
he was using the tool improperly. So even the proper tool can produce a
bad job if you do not know what a good crimped connection looks like.
Unfortunately, West Mountain Radio does not provide any instructions
with the tool.

myself... having a number fall out over time. Fortunately none fell into
'sensitive' electronic areas... they just fall out...
I didn't have have all that good luck with Super Glues either... not sure
why, but the several times I tried them did not end well, with the
connectors
STILL coming apart.
I think I like the idea of filling the 'roll pin hole' with hot glue.
That
seems like a much more viable method.
I currently use a short length of #12 solid copper wire, stuck thru
the hole
and then bent (on both ends) around at least two sides of each of the APP
connector shells. This method allows for a slight amount of movement
between
the shells, but it does keep them together and in a manner which
allows for
complete disassembly if necessary at a later time. It's not terribly
'pretty',
but it does work.
