DXpediton style
take 3-4 feet of bare solid # 10 # 12 copper wire and make a loop around the
base of the antenna support- make it larger if necessary, wrap and solder the
ends of the loop
Wrap a couple turns from each radial around the loop wire. Solder. The joints
are far enough apart to make soldering reasonably easy even with MANY radials.
If you must use a dis similar metal, use the same technique and split bolt wire
clamps, feed two at a time through each split bolt
Run as heavy a wire as you think necessary from the ground ring to the feedline
shield, transformer return, whatever goes to ground.

I've done it two ways. There's a DX Eng radial plate at the base of my Tee
vertical connecting a very large number of on-ground radials. For a couple of
verticals sloping off my 120 ft tower, fed at their base and using the tower
as a passive reflector, I use copper split-bolt connectors to connect four
elevated radials for each sloper. I also use split-bolts to connect on-ground
radials for the tower (it needs a good radial system because it's a passive
reflector).
