I don't understand these suggestions.   Steve asked about perpendicular connections, not inline, and using split bolts means that one or both of the soft copper wires is going to be under buffeting tension while making a bend around a sharp edge.  That seems like a recipe for a failure.

As a practical matter, with a split bolt, there's not much bend with two wires at 90 degrees.



The rope and tail connection idea proposed by others makes far more sense to me.  Run a rope from the tower to an egg insulator near the ring.  Loop the radial wire through the egg insulator with enough of a tail to solder to the ring.  The ring wire can (and probably should) run through one of the holes in the egg insulator as well.

And by the way, silver solder ... like plumbing solder ... should hold up for ages.  It's tin-lead solder that degrades in weather.

    Steve needs help Joining wires:
<SNIP>
I need to electrically and mechanically join 2 perpendicular pieces of
bare, #12 copper wire. They will be subject to wind forces which have
repeatedly broken mere solder joints.

Suggestions ?

Once again, Google is your friend:
[ https://www.instructables.com/Master-a-perfect-inline-wire-splice-everytime/ | https://www.instructables.com/Master-a-perfect-inline-wire-splice-everytime/ ]

This should give you the mechanical strength you need. Remember that solder will deteriorate when exposed to weather so protect the splice.
You can also, sometimes, find aluminum split bolts for 12 ga wire.

Good luck.
