I bought 3 off 35mm OD 3mm wall thickness tubular hand rails, each 3.5 meters long, off Ebay for £54 delivered, and these will make 6 good ground rods, I hope. I did consider 22mm copper water pipe, but the moderns stuff is so soft and thin walled I worried about getting them in, I can't realistically run a water hose to some places I want to put them in, to try the pressurised water down them, to erode the soil away, and digging down say 4 feet is messy as I would at best have a hole 18 inches square, and possibly bigger if the soil started to collapse. The tractor on the lawn with the post hole borer is a definite no no, the wife would skin me alive if I left wheel ruts! Anyone know how much better galvanised "clean" rods are compared to uncoated mild steel, that will rust in weeks? -- Best regards, Chris mailto:chris@chriswilson.tv
