| There
are now 32 species growing widely across the UK, some
introduced over the ages, other propagating naturally,
some even ever green! All feature catkins, and acorns,
those details we expect to see in our woodland and countryside.
The catkin, typically produced in May, is the Oaks
male flower, and pale green in colour. The female is
less conspicuous. The nut, the acorn, contains one seed
(very rarely two or three), and can take 6 – 18
months to develop.
A new tree can take between 20 and 50 years to produce
first crops of acorns. By the time the tree is 80 years
old, it may well be over 20” (50.8cm) in diameter.
The largest Oak recorded was a Newlands Oak and its
trunk was a staggering 45 feet (13.72 metres) diameter
when it fell. Today, the UK’s largest Oak is called
the Major Oak and stands in Sherwood Forest, this tree
measures 33 feet (10.07 metres) in diameter.
PROCESSES
Valley Oak receive timber in the log. We will choose
upon receipt whether it is best left in the log, or
milled straight away. This may depend on the time of
year the tree is felled or whether it is in sap or not.
When ready, the timber is milled on site. All is cut
into 2½” (63.5mm) section (which after
finishing results in the nominal 60mm finished section)
with the exception of the feet, which is larger still.
The milled timber will be stacked until required, with
lats between boards to allow air across the surfaces.
We now have the start of the drying period. If allowed
to air dry, timber of this section will take in excess
of 2 years. The moisture content during the curing process
will drop from about 60%, to 16%.
The vast majority of the timber used by Valley Oak
to build our furniture is green – in other words
not dried, either naturally or by force drying in kilns.
The exception to this, timber stocks permitting, is
the board we use to make the butterflied table tops
where we will endeavour to use partially cured timber
to minimise the shaking (cracking, splitting, twisting
etc.) when built.
As Oak dries, the moisture within it dries out through
the surfaces, particularly the end grain. Since the
outside dries before the inside tremendous stresses
build up within the timber. As the timber dries it shrinks
up to 2.5% across the grain, but virtually none with
the grain. To try and even out moisture loss, Valley
Oak regularly apply a partial sealing compound to the
end grain.
Build of the furniture is fundamentally a manual process,
although power operated hand held tools are used. Each
piece of timber is picked for its features, which, although
regularly making the working of it much more challenging,
produces unique and truly beautiful pieces of work.
At Valley Oak we strive to give our products the best
possible start. Over time it is to be expected that
the appearance of each piece of individually hand crafted
furniture will change, however with careful maintenance
we are sure that our products will compliment your garden
for years to come,
When built all surfaces are treated, to slow down surface
drying, promote waterproofing and preserve. See
