In this part of the world one can buy joiners for the rods. The idea
would be you cut them in two, then when you install them, drive the
first rod, put the joiner on, place the second rod in the joiner,
drive it etc. That's how rods of tens of metres are driven in.

Maybe those joiners are available from you electrical contractors
suppliers.

Interesting approach but I've never run into any such things on this
side of the pond. I'll ask an electrician or electrical supply house.
Tnx.


Brian, these ferrules are for copper clad steel electrodes. The are
slimline, and have a hole with a slow taper bored in each end. They
are "connected" during the driving process, no silver soldering etc.
They cost about six pacific pesos for half inch rods, equivalent to
about $4+ of your money.
