might have been me
my dad predated post buddy by using bed angle irons (old beds used to have 6ft long 2″x 2″ thin angle metal frame bits – dad used this on our posts and it worked well(and still is – 10 yrs later) – I saw post buddy and have a fence with 7 posts – 2 gone,but sadly I gave the bed angles he gave to me to a ragbo at a house move
anyway now fixed – top tip – can you put in new posts and leave the old ones there – the repair spurs look scabby (imho – and will be even more of a digout if they go) and make sure you get the new plastic sleeved/bitumen sleeved 15 yr gtee posts (have a sleeve at ground level)
