I am looking to construct an archway in the garden. I have the design
all worked out and it will be lashed together with rope and secured to
the ground with concrete footings - probably with some soil to cover
the top of the concrete.
The question is - what wood do I use for the construction? I have
found the following options :
"Grown from the Eucalyptus Grandis tree these poles have a natural
taper over their length. They are also very strong, their density is
similar to oak, and their natural appearance make them perfect for a
variety of uses. All poles are stripped of bark, Tanalith E treated,
and are far stronger than bamboo or machine round alternatives. They
are strong enough to be used in building construction."
Telegraph poles - ACQ treated, new. A choice here appears to be either
stripped of bark and supplied as is, or machined to give a uniform
Chestnut from a managed woodland in East Sussex. Not treated, but can
have the bark stripped if required.
My criteria would be (in order) Long lasting (Ie. not rotting through
at the base) and natural looking. I am guessing the first option
(Eucalyptus) is imported so would prefer something 'local' (at least
from this country!). And I am lead to believe the heart wood of
Chestnut is such that it will not rot for a long time without needing
to be treated.
Any advice or opinions (or resources!) would be helpful!
