Description: |
|
The hickories are an important group within the Eastern
hardwood forests. Botanically they are split into two groups; the true
hickories and the pecan hickories (fruit bearing). The wood is virtually
the same for both and is usually sold together. The sapwood of hickory is
white, tinged with brown, while the heartwood is pale to reddish brown.
Both are coarse textured and the grain is usually straight, but can be wavy
or irregular. |

Working Properties: |
|
The hickories are considered difficult to machine and glue
and are very hard to work with hand tools, so care is needed. They hold
nails and screws well but there is a tendency to split, so pre-boring is
advised. The wood can be sanded and polished to a good finish. It can be
difficult to dry and has a large shrinkage. |

Physical Properties: |
|
The density and strength of
the hickories will vary according to the rate of growth, with the true
hickories generally showing higher values than the pecan hickories. The
wood is well known for its very good strength and shock resistance and it
also has excellent steam bending properties. |
