[QUOTE="Channel Hopper, post: 1072572, member: 175144"] I have a digging thing, but it is for a four to six inch diameter post, far too large for what is needed on site. [URL unfurl="true"]https://www.toolstation.com/draper-post-hole-digger/p16835?utm_source=googleshopping&utm_medium=feed&utm_campaign=googleshoppingfeed&gclid=CJWN-8bd3OICFQMM0wodn_kCxw[/URL] Anyhow I'm going to have a go at home since the garden is large enough for at least a 10 yard gap between the two spikes, in most directions, though I will start with an East/West line (for no reason other than Sweden having its Grimton demonstration in a couple of weeks time). There are a number of trees though so I will have to experiment with smaller holes for roots and debris from the original house build. I found this document online that provides the depth and frequencies for various soil consistencies, though it does not mention ideal distance between spikes. I am hoping to go just below 2m with what I have, possibly close enough to the water table. I've also found a suitable substitute for copper in the shed, a couple of brass curtain rods that come complete with screw terminals. Using these means I don't need to drive anything greater into the ground than 2 inches in diameter, I have plenty of scaffold pole, steel gazebo posts and a lump hammer, plus some hilti style drills that are a yard or so long to cut through anything that gets in the way. Will take pictures of progress. [/QUOTE]
