Hull-Oakes Lumber is the last steam-powered
commerical saw mill in the country, and they're
one of the few mills capable of cutting large
timbers up to 85' long. The mill has been
on the National Register of Historic Places
since 1996. Large long timbers are still used
in railroad trestles, the restoration of historic
structures, and for the spars and masts of
ships. By coincidence, the day I arrived the
mill was cutting an 80 ft. long timber for
the restoration of the C.A. Thayer, an early
20th century three-masted schooner used to
transport lumber along the West Coast

In 1934 Ralph Hull went into the
sawmill business by leasing a mill which had
been closed since the depression. Hull
started building a plant on the current site
in 1938, Right up until he passed away, in May,
2002, he continued to check in on operations,
but his grandson, Todd Nystrom, now runs the
mill, located about fifteen miles south of Corvallis,
Or. |

| OPERATION
OF THE MILL |
| |
| Trucks
arrive loaded with logs.
The waggoner, a log-handling machine, grabs
the logs before the binders are released, then
lifts the logs clear of the truck.
|
| |
| The truck
pulls out and...
|
| |
|
the waggoner drops the logs over the log brow
and ...
|
| |
| into
the log pond.
|
| |
| Then
the truck backs up under the A-frame hoist,
the driver releases the trailer...
|
| |
| and the
trailer is hoisted "piggy back" onto
the truck.
|
| |
| The waggoner
operator also doubles as the "pond monkey."
Back in the early 20th century, a pondman walked
the logs in the pond, arranging them with a
pikepole and stacking them at the log lift.
|
| |
| But today
a pond boat quickly shuffles the logs, picking
and ordering them at the base of the lift, so
the boat operator is often called a "pond
bronc."
|
| |
| The bark
that accumulates in the pond is lifted on a
conveyor up to the mill, where it's transported
to the chipper. All debris goes to the
chipper.
|
| |
| Once
the logs are ordered and stacked ready to be
lifted, the boat operator goes back to off-load
another truck of logs.
|
| |
| The log-lift
hoists the logs individually out of the pond
and...
|
| |
| drops
them into a chain-driven conveyor, called the
'long transfer', that transports the logs through...
|
| |
| the barker,
where the bark is stripped off and conveyed
to the chipper.
|
| |
| The logs
continue on the conveyor to the 'short transfer'
or log table, where they stack up. The sprocket-and-chain
operated table moves the logs individually to
the log cradle (hooked bar on left) which holds
each log in preparation for a short tumble down
to the log deck and the log turner.
|
| |
| The log
turner lifts, rolls, and shoves each log onto
the carriage. The heavy steel arms--operated
by steam cylinders--can throw around a six-foot
diameter, eighty-foot long log. At the
right side of the photograph, the next log is
held by the cradle.
|
| |
| This
80 ft. log is carefully rolled and positioned
in the carriage prior to making the first cut.
All the cutting operations are powered by steam.
|
| |
| Now the
log has been rotated to minimize waste. The
first cut removes mostly wane--the round and
bark-covered edge of the log.
|
| |
| The off-bearer
(right side of photo) secures the fall-off until
the log clears the blade, though large logs
require more help. Here the ratchet setter
lends a hand, too.
|
| |
| The carriage
rides on tracks, like a railroad car.
The movement of the carriage is controled by
the sawyer.
|
| |
| The sawyer
looks at his order board then motions to the
rachet setter, who operates the carriage, racheting
the log closer or farther from the blade. Hand
signals are the only way to communicate with
all the thunderous noise. Everyone wears
ear protection.
|
| |
| The
sawyer and the rachet setter must be sharp and
quick, as the carriage moves the log past the
blade quickly. Two fingers means the log must
be moved out for a two-inch cut; a fist or a
connected finger and thumb followed by four
fingers means a 14 in. cut. In this way,
the rachet setter knows that the carraige must
be returned to the log turner so the log can
be rotated before the next cut.
|
| |
| The Sawyer
controls the movement of the carriage with the
wooden-handled lever on the left, while simulataneously
controlling log-loading and log-turning with
the control on the right. The control on the
right also operates the 'short transfer' chain
conveyor and the log cradle.
|
| |
| The rachet-setter
is seated behind controls that operate the movement
of the log on the carriage, and controls that
secure the log to the carriage.
|
| |
| This
log now lies flat on a clean cut, ready for
another pass through the band mill, which squares
the timber in preparation for making a new mast
for the C.A. Thayer. The mast is so long
that transporting the log required a truck-and-trailor
with stearable rear wheels. The finished
timber will be transported by barge to the ship
restoration project in San Francisco.
|
| |
| The off-bearer
works right beside the blade, as the mill squares
up the timber.
|
| |
| The off-bearer
relies on an assortment of tools to help move
both slabs and sawdust away from the headrig.
|
| |
| Measuring
the final cut.
|
| |
| Long
timbers become a hands-on operation when they've
developed a slight bow.
|
| |
| Hull-Oakes
specializes in cutting long logs and big ones,
too, over 6-ft. in diameter.
|
| |
| The off-bearer
guides the second cut onto the rollers,
|
| |
| and helps
pivot the slab slightly. Gravity does
the rest.
|
| |
| The slab
is shoved tight against the straight-edge fence
of the edger table before going through the
edger.
|
| |
| The edger
cuts wide slabs...
|
| |
| into
narrower beams and boards.
|
| |
| All the
fall off, the bark, the wane and waste, goes
into the wood chipper. Some of the resulting
material is used to fire the boilers, but most
of the chips are shipped to Toledo, a nearby
paper company.
|
| |
| After
cross-cutting for length,
|
| |
| timbers
and beams are hoisted to a pallet, loaded on
a lumber carrier,
|
| |
| and stacked
ready for shipment.
|
| |
| THE
HEADRIG |
| |
| The over-sized
bandsaw blade runs around two wheels in the
headrig. The headrig includes the blade,
pulleys, and protective housing.
|
| |
| The blade
is removed for sharpening every two hours.
The doors on the blade housing swing open and
a carraige moves the blade off the pulleys...
|
| |
| then
lowers the blade to the ground. The saw
filer, with assistance,
|
| |
| guides
the blade onto a long dolly.
|
| |
| It only
takes two men to position the blade
|
| |
| in several
careful steps
|
| |
| into
the sharpening station.
|
| |
| The carborundum
grinder must be dressed before sharpening each
blade, then the saw filer calibrates the machine
for the stone, adjusts the travelers, and starts
the machine, which
|
| |
| runs
automatically.
|
| |
| Though
the saw filer still has to keep an eye on the
process.
|
| |
| The shark-size
teeth on this blade are a little larger than
those found on most band-saw blades.
|
| |
| This
old boiler, now used to store water, has the
doors removed, revealing the inner tubing.
|
| |
| The heat
from the fire below circulates through the tubes,
boiling the water within the tank.
|
| |
| The fires
are fueled bya mixture of sawdust, planer dust,
and bark,
|
| |
| transported
on conveyor belts from the mill
|
| |
| and fed
into the furnaces. Two boilers supply
steam to the steam engines.
|
| |
| The headrig,
carriage, edger, and log-table are powered by
steam engines. The main engine, an Ames
twin-cylinder, built in 1906 and still operating,
powers the headrig and edger. A second
steam engine powers the carriage, which is drawn
back and forth on its tracks by a cable-and-pulley
system.
|
| |
| The steam
engines have fewer breakdowns than any other
equipment at the mill. The larger engine
has two 16 in. cylinders, an 18” stroke,
and the pulley is 8’ in diameter. The
engine is 13’ long and 10’5”
wide.
|
| |
| But it's
an assortment of chains...
|
| |
| sprockets...
|
| |
| and gears
that provide the fine tuning power of this mill.
|
| |
| Bill
Oakes adjusts the steam pressure feeding the
engines. Bill's family, like many employees
at the mill, has a long history of working at
the mill: his father, Ken Oakes, fell timber
in the logging woods for forty years, providing
logs for the mill. Ken retired at the age of
71 and past away in September 2001 in his 90th
year. Today, Bill's grandson pulls and sorts
lumber at Hull-Oakes.
|
| |
| The operation
of the mill is dependent upon the millwrights,
who repair everything from hydraulic lines,
to steam engines, to boilers..
|
| |
| The millwrights
have to know every inch of the plant, and how
to operate nearly every aspect of the mill.
