Another thought is to use concrete repair spurs set in concrete, with
the posts bolted to these. There are some repaired posts in the garden
like this already - they've been there 20+ years and and rock solid.

Any thoughts on concreting these in? I can't believe one bag of
postcrete is enough for a 1.6m high fence on 3m spaced posts.

It's how far into the ground the post goes that stops it falling over
rather than a mass around it. Postcrete is just a quick and simple
way of filling the space around the post. Rammed earth will do just
as well. Best if the post is snug in the hole, so a post borer or
post hole digger thingy rather than an 8" spade. Rule of thumb is 1/3
total post in the ground so 6' out of the ground, 2' in - 8' post.


Is it just me or...

No.

though it (a) is a reflection of the common advice to sink 1/4 to 1/3 of
the post - depending on soil, wind load etc. and (b) possibly to be
welcomed as part of a cunning programme of neurological stimulation for
declining Usenet users
