Hi Randy,
I rebuilt my shack six years ago, and documented a bit of that. One
part was connecting grounds to the back of the rigs. See:
https://www.nk7z.net/rebuilding-the-shack/
Look at a few of the photos. One shows a large copper ring terminal,
which will fit a K3, etc., and how it was connected to 3/4 inch braid.
Basically I folded the braid, inserted it and some solder cut to length
into the ring terminal solder bucket. I then held it in place with a
set of pliers, and hit the ring terminal with a Burns-O-Matic torch.
You can see the jig I had set up on the top of the glass jar.
Yes... I know grounds are not supposed to be soldered...
I am sure there are better ways... This is just what I did.
73, and thanks,
Dave (NK7Z)

I'm currently in the process of wiring up my new station and I happen to
be working on the equipment bonding phase for my pair of K3s SO2R
station. I'm doing my best to get decent connectivity between the
station components, but can't really figure out how to terminate large
(AWG 10) wire to the teeny 6-32 ground screws on the back of the K3,
especially since something like six bond wires need to be attached to
the transceivers. There appear to be no available ring terminals that
will fit these small screws; the smallest I can find are for #10 studs.
Even by using a threaded standoff installed in the K3 ground nut and a
longer screw to stand the rings off, stacking a bunch of these huge
terminals is extremely difficult. Providing some means of reasonably
quick disconnect for servicing purposes is equally difficult. Exactly
how can I go about connecting big wires to little ground posts?

I'm asking what method and
attachment point, to each piece of equipment, you experienced K-Line
owners
use to bond the K3s, P3, SP3, etc. and then on to the station ground.
I use wires soldered to screw lugs, making sure that the attachment
point is not insulated from the chassis by paint. Some of the
equipment has a dedicated grounding screw. Shells of DB connectors
SHOULD be bonded to the equipment chassis, but not always -- some mfrs
screw up and fail to do that.
Some of my equipment goes out in the field from time to time, so I use
single circuit Power Pole connectors to make that easy. I'll use 2-6"
between the lug and the PowerPole, then make a loop soldered to a
PowerPoles that connect to each piece of gear in the string (so each
connector has two wires). There are lots of suitable variations on
this, depending on how the shack is laid out.
These are the slides for my talks on station power, grounding, and
bonding. http://k9yc.com/GroundingAndAudio.pdf
