GREENHEART
(Ocotea rodiei) Explosive as well as poisonous, greenheart does
have some good qualities -- like durability that rivals teak's. Sawyers
in Guyana, Surinam, and Venezuela have nasty enough work in the tropical
heat day in and day out without worrying about exploding logs on top of
it all. But when a load of greenheart comes to the mill, they treat the
logs like a truckload of ticking time bombs.
Greenheart it seems, has an usual tendency to split apart so quickly and
with such force that pieces of the log can fly when air hits the saw
kerf. In at least one instance, sections of a greenheart log actually
pierced a mill roof. To prevent such mishaps, mill hands secure the
section of the log that has already passed through the saw with a stout
chain.
As if controlling greenheart's explosive tendency isn't a scary enough
situation, all who work the wood also must avoid getting splinters.
That's because greenheart, while nontoxic and nonirritating to the
touch, somehow causes severe infection when splinters of it penetrate
the skin.
"Why do these lumberman even bother with the wood?" For several reasons.
Besides being a pretty wood, greenheart ranks second only to teak in its
natural resistance to marine borers and other insects attacks.
It also has high shock resistance, great crushing strength, a high
density, and takes a polish with little effort. Such attributes attract
ship and boat builders. Before man-made materials, fishing rod makers
liked greenheart because it bent without breaking. |
