[Elecraft] ESD question

I use a low cost earth mat and wrist strap. In order to connect them
together (and to earth) I have an aluminium bar alongside the work
bench, this in turn connects via a length of "hook up" wire and
crocodile clip to the station ground. At the start of each session I
check there is continuity between the mains earth and the bar using a
multimeter.

Obviously, some crocodile clips are better than others... 4mm plugs are
fitted to the mat and strap, so if yours have these you may consider
making a small box with matching sockets and then a flying earth lead to
a station ground.

You didn't mention an earth mat, these are very handy but I would avoid
the field service types with the component and lead "pockets" as the
flat rubber bench mats are generally nicer to use on a bench. Some mats
can be very expensive, I use the Maplin (UK electronic supplier) part
number YJ90X mat, however Maplin seem to have "discontinued" all their
mats and only stock wrist straps! Maybe standards are slipping, or folks
just don't understand the need for mats as well as straps.
