I did the post yesterday using the Metpost repair spur
kindly suggested by Clive Summerfield.
I bought a new post, but thought afterwards that I
could have turned the old post upside down and used
that, sawing off the top.
The spike wend down the edge of the old post in
the concrete, but it was a n ightmare to get it vertical....
one tap down with the sledgehammer then three on the
sides to get it vertical, one tap down.....
The inside of the spike that receives the post has 'fins'
that bite into the post to hold it steady, plus the inside
is bigger that the post it takes. I therefore found it
impossible to locate the new post in exactly the same
place as the old one, and had to do a lot of fixing to
get the fence panels attached to the new post. I noticed
later that my local garden centre sells 'Quikposts' that
have a smaller socket for the post, and you tighten
*bolts* to hold the spike to the post.
Always best to paint the bottoms of wooden posts with a thick bitumen paint,
on top the preserver paint, before burying them in the ground or in MetPost
sockets. That way they last for years and years with only a top up of
preserver every so often.
Some ~17 years ago, I built a feather boarded arris rail fence which
is still standing fine. I used Fensock post holders which had a nut and
bolt clamp to hold the post, so you could position it vertical and then
tighten the clamp. The sockets hold the post bases slightly off the
ground. Don't know if they still exist as a product though. I found
you needed to buy 10-20% more post sockets than you needed as every now
and then one would hit a lump of concrete or similar and end up with
U-shaped spike which was no good.
Incidently, I could do with some 4" metaposts for a (different) fence
which has lost a couple of posts concreted into the ground. When I
looked around, the type you hammer into an existing hole only seemed
to come for 3" posts. Anyone seen 4" ones?
I found that Metposts into the old stumps didn't hold the post solidly.
They were also nigh on impossible to get in vertical, as you mention..
After losing fence panels for a third time, I bit the bullet and went for a
proper repair. I used 4ft concrete posts sunk 2ft into the ground next to
each wooden post. This did mean digging out the old concrete from around
the wooden posts, and was a lot of hard work, but the fence hasn't budged an
