Actually, it's not the crimp job that kills the connection. It's the
stripping of the coax that causes the most problems. I use various
rotary contrivances that have razor blades to make the cuts at the
correct spacing. Those work well initially, but after about 50
connectors, the blades become dull and useless. Of course, nobody has
spare blades or knows how to adjust them. They either continue to use
a dull razor or steal my new stripper.

Oops... dinner... gone.

The problem with the dull cutter usually creates problems where the
dielectric ends, and where the solid center conductor is exposed. The
dull blade pushes the aluminum shield over the end of the dielectric,
shorting the aluminum or the braid wire to the center conductor. Even
if it doesn't immediately short, some movement of the cable can cause
it to short. When it gets to this point, I have to take a sharp knife
and cut back the shielding so that it won't short. However, once the
connector is pushed in place, it can't be checked or repaired.

I can offer several other ways to do it wrong, but that should suffice
for now.
