I have a sound concrete base where the post has rotted just above concrete level. Do I excavate out the rotten wood from down inside the concrete and then this slots in the hole where the post was, and then new post into the top?

sorry

all metal spikes are rubbish. I had a similar job (just one) where I used an extra-long large drill into the rotted stump, to my surprise I was able to pull it out. I had intended to drill it to fraghments like a dentsit. I presume it had shrunk a bit since the concrete was cast, or possibly the heat from the drill dried it out a bit, it did not feel loose before. In my case I then slid a concrete spur down the hole (it fitted) as I prefer them.

how does it work.....badly. there only good for scrap metal in my opinion.

take the old one out and concrete in a new one

cut flush to the top of the concrete and hammer the boot into the hole.. it should wedge between the old post stump and the concrete..

and wobble like hell. Ive said it before and ill say it again. Ive lost count of how many of these weve ripped out when we replace fences.
