I agree. There's also the matter of HOW you whack the pole. Many years
ago, I spent time on a service bench fixing things, and later spent time
doing field service. Banging on things can be a good way to find
intermittent problems, but HOW and WHERE you choose to do your banging
can be a bit of an art.
