Some of the bark it didn't come off, so they had men at the end of this thing letting the wood that was clean go either to the flume or the chipper. The wood that wasn't clean, they had to pull off in a conveyor and use the hand barkers. There were 4 or 5 of these hand barkers--huge things that had a big disc on them with knives on them. And a man had to hold the wood either mechanically or with their fingers.

A 48-inch Hansel Ring Barker was finally chosen. The in feed and out feed conveyors at the barker will consist of H chain with attachments for centering the logs. The roll cases and chain conveyors feeding the barker will be fully reversible. The roll cases will be arranged to travel at 180 feet per minute. The chain conveyors will have variable-speed drives to run at from 50 to 120 feet per minute depending on log size and relative ease of barking. The barker will be provided with both horizontal and vertical movement to adjust its location to suit varying log diameters and bowed logs. It is anticipated that a log of maximum diameter of 44 inches will be passed through the barker. Though designs generally have been based on 36-in-diameter logs, nothing has been done to prevent the passage of an occasional log over 36 inches and up to 44 inches in diameter.
Water for the barker will be passed through three AWF 116 Adams Poro-Stone Automatic Back Flushing Water Filters.
Initial barking pressure will be 1,325 pounds per square inch. It may possibly be increased to at least 1,450 pounds per square inch, in line with similar existing installations.

The logs that go to the saw mill can be converted into blocks for the Grinder Rooms, or cants which can be handled by the chipper. From the Chipper Building, if we follow the chips, we go up a conveyor belt to the chip surge bins in the Chip Screen Building. This lies alongside the hot fuel belt in the bridge. Friendly like, is the chip conveyor belt, carrying chips from the screens to the Digester House.

Often a high school students introduction to mill work began on the block loaders. It was a great lesson about what happens when machinery controls you, not when you control the machinery. Just about the time you were getting bored and tired and ready for a break, the damn thing would go into warp speed and spit out a tremendous pile of wood that had to be straightened in your little work space or the big guys beside and across from you would have to do it for you. And they always seemed to be in a bad temper. And, of course, you were reminded of the last guy who didn't pull his weight and went home with a picaroon buried in his head.

Unnoticed often in the steady purr of the paper machines, the crushing roar of the barkers, the slushy immensity of the digesters, the howitzer like magnitude of the grinders, the great furnace of the steam plant, is another vital "pawn" in the manufacturing of Powell River newsprint-the filing room.

Daily, in the two eight-hour shifts, close to half a million feet of logs are sawn, ripped and cut in the Powell River sawmill. Logs varying in diameter from one to six feet are bumped boisterously on to the carriage and "shot gunned" through the big 16-in band saws. They pass through the edgers to be cut longitudinally-and then on to the "slasher" for cutting into block size.

Little imagination is required to picture the wear and tear of this incessant friction on the saws, and the necessity of having fresh relays of sharpened edges ready to throw in at regular intervals. And here it is that the filing room, under the head filer and his capable assistants, swing into action.

The maintenance routine on a 10-foot head rig band saw is typical. The designation "10-foot" refers to the diameter of the top and bottom wheels of the band saw. The actual length of the 16" wide band saw blade itself is nearly 60 feet and it has 286 teeth, one every 2 � inches. When the teeth are merely dull, a grinding stone is adjusted to the shape of the tooth and the saw can then be sharpened automatically. But on every third visit of the saw to the filing room the teeth must be individually rebuilt.

This intricate operation requires a high degree of experience and knowledge. Each tooth must be had swaged, an operation in which the steel is hammered to the correct thickness using a high pressure air anvil. The teeth are then individually shaped and, finally, sharpened.
