Other names
sycamore plane, great maple.
Distribution
Sycamore is native to central Europe and western Asia. It appears to have
been introduced into Britain from the Continent in the fifteenth century.
The tree
Sycamore grows to a height of 30m or more and a diameter of 1.5m. It is
tolerant of widely differing soil and exposure conditions, standing up well to
the fumes of industrial areas and the salt-laden gales of coastal regions.
The timber
There is no difference by colour between sapwood and heart-wood, the wood
being white, or yellowish-white when freshly cut, with a natural lustre
especially noticeable on quarter-sawn surfaces. It is generally straight grained
but may be curly or wavy grained, and the texture is fine. The average weight is
630 kg/rn3 when dried.
Drying
It air dries well, but is inclined to stain, and rapid surface drying is
necessary to prevent this. The use of thick stickers helps, but kiln drying at
low temperatures is probably the best treatment. Rapid air drying preserves the
white appearance of the wood, sometimes achieved by end-racking the boards,
while slow drying gives the wood a light-brown colour, referred to as weathered
sycamore, but the aim must always be the avoidance of stick marks which
penetrate well into the wood, and this can only be successful if the surfaces
are dried rapidly.
Strength
Sycamore has high strength properties similar to those of oak.
Durability
Perishable.
Working qualities
Fairly easy to work and machine, and capable of a fine, smooth finish when
straight grained; material with curly or wavy grain picks up in planing and
moulding and a reduction of the cutting angle to 15o is needed in
order to obtain a good finish. It turns excellently, can be glued. stained and
polished.
Uses
Turnery, bobbins, textile rollers, brush handles, furniture, flooring and
for decorative veneer. Harewood is sycamore that has been artificially dyed grey,
and at one time was much in demand for panelling. |
