Unearthed the previous fan of plumbers' copper microbore tubes
and associated ground rod to find a corroded and non conductive
mess and raised the question of how to protect underground
junctions from the worst that nature could throw at them?
Firstly, resurrecting a technique from school metalwork lessons
from 53 years ago when brazing things together, dig out the
gas torch, soldering flux***** and solder and connect all together
electrically.
Secondly, to protect the now-relatively-massive joint, smear with
petroleum grease. Was this a good idea, and is there something better?
***** Curious as to whether could be combined with one's radio
interest to nake a flux capacitor to go time travellingg :-)
cathodic protection?
Galvanising !
Can't see how to do that when it's all still in the ground with just
the ends showing :-)
