Back in the day, we were taught to use a short (1/2") bristle, brass brush -
like a flux brush - to "comb" the braid out over the clamp ring, and then we
used small scissors to trim the braid to final length.

One "trick" to properly installing an N connector is that you have to
separate all of the strands around the ring. You can not have any that
overlap each other at the point where they get clamped. It is kind of a pain
to separate them but it pays off. They won't work loose if done this way.
Use a sharp point like a marking scribe to separate the strands.
They need to be cut to proper length too.
