how deep do I need to plant a 4m high pole?
Gareth
SWMBO has said she wants a washing line like our neighbours.
This appears to be supported by a ~4m high scaffold pole at each end and
a pulley to raise and lower the line. How can I work out how deep I
need to bury the pole to support 4m of pole above ground?
Thanks for any help.

Rule of thumb is 20% in the ground I reckon.

You'll need to start off with a 5m pole and put 1m of it underground, also,
lean it backwards slightly from the opposite pole, don't put it upright,
because it will flex quite a lot and if it's upright, when loaded it will
lean quite dramatically towards the opposing pole.

I would suggest finding a suitable sleeve to hammer into the
ground flush (or concrete in the ground) into which you slot
the longer pole. I use the ground socket spikes for clothes
airers for 3 metre light weight aluminium poles with no more
lateral force than the wind, but you'll want something more
substantial for a 4m scaffold pole with a line pulling on
it, and I've only seen them for 1.25" and 1.5" poles (IIRC,
scaffolding is 2").

The neigbours have probably used a standard length of pole, which
suggests they have either 1m or 2.4m buried.

IIRC its in 3.2m ex stock, longer lengths to order.

I usually do 33% below-ground as a general rule.
If you don't want it to flex, maybe use something stronger than scaffold
(our line has telegraph poles at either end, supporting four lines of
around 30' in length - it's a bit of a monster ;-)

Thanks for your reply.
Is that 33% of the total length or the above ground length? I.e for 4m
above ground do I need 2m or 1.3m below ground?

I don't want it to flex but a telegraph pole seems a bit excessive for a
washing line - maybe a tumble dryer would be easier :)

Good point - I hadn't considered that.

We used a scaffold pole about 8' high with about 2' in the ground (10'
total) with concreted rubble and bricks. I.e, dig 2' hole, maybe 18" wide,
drop in pole and fill with rubble, bricks, cement. My !"£$" son ran at it
one day, grabbed it as he passed causing it to bend starting at about 3' up
with the top ending up about 12" from where it was. Absolutely zero sign of
movement at ground level, still firm as a rock. I still can't believe it.

No that would be stupid. I was thinking of welding the pole to the side
of the drier rather than sticking the pole in the ground :)

If you put blades on it, you could make the drier spin in the wind,
generate its own power and save the planet.

put too much washing on the line.
Dont they do proper clothes poles nowadays, they used (years ago) to have
them about 2 meters high and sunk in a lump of concrete, i think no more
than a couple of feet deep and never seen one topple over yet. Usually done
with 3 poles (triangle ) or a square with 4 poles.

Our local timberyard still sells proper galvanised washing poles with
the two crossed bars at the top. Ours started as 2.5m but I sank the
first foot or so in a large lump of concrete. That was a few years ago
and it ain't moved yet.

Yes, it should be in a LARGE lump of concrete as the sideways pull is
pretty significant.
Remember the washing goes out semi dry having been spun, but like
cricket matches, that's a signal to the rain gods to perform and the
washing then gets really heavy - the wind gods then do their thing
and low and behold, if you don't put some serious weight at the foot
of each pole, everyone's efforts will be in vain and you certainly
will be in the doghouse.
I took two poles out and the concrete mass must have been at least 2
ft in diameter. Fortunately I had a mini digger available to lift
them and bury them in another hole. Just bear the this in mind as
once in they are not easily removable.
Convince SWMBO to stick to a whirligig - can be put anywhere and is a
nominally balanced load so none of these problems exist. OK they have
a finite lifetime but I suspect that a replacement every 10 years is
preferable.

My ten foot scaffolding poles are hammered in about two-three feet and
have slightly moved inwards towards the centre but not enough to worry
about. they have been there five years without any problems and get
used a lot.

Depends on the garden and the wife. Our garden isn't well suited to a
whirlygig and neither is the wife.

We have a rotary washing line which is at least 60 years old (and still working well).
It is of a much heavier construction than today's flimsy-looking things.

What makes a wife unsuitable for a whirlygig?

33% of total length - that's what I was always told and so what I usually
go by with posts, but I don't know if it's any kind of "industry
standard" :-) Others have mentioned 25% and maybe that's fine (although a
scaffold pole + damp washing in the wind will be a fair old force trying
to pull things over, I'd think)

;-) Yeah, it's a monster of a setup - the lines are all solid fencing
wire several mm thick, too. Bet it was put in by previous owners decades
ago.

Cerebral palsy - she likes the line to stay still when she leans on it
for support rather than flip her into next door's garden.

washing, on the "sail area" of the washing and the exposure to local wind, and
on the degree of line sag allowable. For the last point, persuade SWMBO to put
socks and undies in the middle, and bedclothes at the ends.
Local geography and SWMBO permitting, you should consider putting guylines
(slope about 45 degrees) at one or both ends. A single in-line guy may suffice
in a sheltered location; a pair splayed at +-30 degrees (more in non-English UK
and in Cornwall) will be better - like a ridge tent but without canvas.
For posterity, plant a pair of trees to use as posts. I was once told, in
Finland, that lightweight Finnish tents do not have poles, just a length of rope
at each end - because, in Finland, one can always find a pair of suitable trees.
