Ramjam, make an adaptor and use the SDS to drive the rod all the way in. no need for drilling.

 

[Ramjam]

I've heard that, what do you make the adapter from? I've been trying to work that out with much ebay searching. Given how hard some things have been to drill I think I'll still sink the drill first rather than spend ours trying to crack rocks with a copper rod.

A socket, bolt, washer and a nut. Our 'leccys invention. The washer soon turns into razor blade I'll post a pic.

Your red sandstone is hardly rocks or do you work the Preseli

Before I bought the drill bit I used a lump hammer and whatever they were it hurt my wrist and on several occasions bent the rod. I love my drill bit, very cheap on ebay!

Guys, why are you bonding? I have spoken to an inverter company and a well respected training company and both now say there is no need to bond the aray when using transformerless inverters. the DTI is currently re writing the guidence notes.

 

[MorganPVI]

We bond because the DTI tell us to. Until it is in writing..................

 

[tottenham steve]

What about manufacturers recomendations? cant seem to find any other guidence re bonding, exept equipotential zones(which is obvious).
