Hi, I want to install a pole-mounted flood light so my lad can continue football training in our back garden over winter. I've bought a 6m section of 60.3mm Galvanised Tube, which I may shorten slightly. The plan is to have somewhere between 3.5m and 4.5m above ground. I'm used to postcreting in fence posts, but I'm not sure if the same principles apply so would appreciate some advice: - what hole dimensions would you advise for leaving either 3.5m or 4.5m above ground? - assuming this is going to need a depth of more than a meter, any suggestions for the best way to dig this? will manual auger be up to the job? - should I be looking at something other than postcrete? - was galvanised tube the right option? All advice gratefully accepted.
