Original Shapes of Band Saw Teeth Should be Maintained L This is ONG experience has definitely established the fact that any alteration of the shapes of Band Saw teeth affects the tension of the blade. particularly so in cases where the depth of gullets is increased. It obviously follows that the best service cannot be secured from a saw that has been subjected to such alterations until it has been properly re-tensioned. The depth of gullets is a particularly important point. Quite a large percentage of filers in the initial sharpening operation on a new saw are inclined to put too heavy a pressure on the emery wheels in the gullets, before they put the saws in commission. Not only is the tension changed by deepening the gullets, but in many cases the extra pressure on the wheels causes case hardening in the gullets. This, with the altered tension, quickly leads to cracks in the saw, and to dissatisfaction. The solution of the difficulty is extremely simple. Keep the original shape and depth of the teeth. The saw is properly tensioned by the manufacturer for just that depth of gullet. Keep the original shape, but get the shape that is just suited to your conditions. Every order for a band saw should be accompanied by complete specifications, or a diagram. You will then have saws which require no alteration of the teeth or gullets; the tension consequently is correct; the danger of cracks from impaired tension and possible case hardening occurring when gullets are materially changed is eliminated, and a lot of unnecessary work for the filer is avoided. Better results are secured from the saw; it lasts longer, and the filer's prestige as an expert is consequently augmented. Even better than a diagram, if you are ordering Disston Saws, would be a steel template. This we will stamp with the name of your company and all future orders will be made from the template. Keep a duplicate for comparison. In this way uniformity is assured, labor and trouble are avoided and the arrangement proves mutually profitable to millman, filer and ourselves. Western Yew From "American Forest Trees" (Taxus Brevifolia) (Continued from July Issue) Copyright Hardwood Record A PROPER crook was selected where a branch joined the trunk, and serviceable fish hooks were made without any cross grain. They They were strong enough to hold the largest fish that ascended the rivers. Sometimes a bone barb was skillfully inserted. The Indians found a further use for this wood as material for canoe paddles. It is so strong that handles can be made small and blades thin without passing the limit of safety. The manufacture of boat paddles from yew continues. More is used for fence posts than for any other one purpose. It is one of the most durable woods known where it must resist conditions conducive to decay. The name yew is said to be derived from a word in a north Europe language meaning everlasting. Yew fence posts are not named in statistics, and it is impossible to quote numbers. Their use is confined to the districts where they grow. The manufacturers of small cabinets draw supplies from this wood, but the fact is not mentioned in Pacific States woodusing statistics. It is particularly liked for turnery, such as small spindles used in furniture and in grill work. It takes an exceptionally fine polish, and the wood's great strength makes the use of slender pieces practicable. Experiments have shown that this wood may be stained with success, but its natural color is so attractive that there is little need of staining unless the purpose is to imitate some more costly wood. If stained black it is an excellent substitute for ebony. Western yew figures little in lumber output. It is not listed in the markets. The few logs which reach sawmills are never again heard of, but probably most of the lumber is disposed of locally to those who need it. The tree is not of good form for saw timber. Burls are said to make beautiful veneer. Trunks are seldom round, but usually grow lopsided. Most of them are too small for sawlogs. The largest are seldom two feet in diameter, and generally not half that large. They are short and branched, the tree often dividing near the ground in several stems. The average tree is scarcely thirty feet high, but a few are twice that. Its growth is (Continued on page 109) The Cherry River Boom Lumber Co. and Dodge Clothespin Co. N the frontispiece and on the following pages are shown I views of the town of Richwood, W. Va., and the Cherry River Boom Lumber Co. The town is picturesquely situated in the mountains of Nicholas County, and has practically been built up by the lumber company. One of the photographs shows in the foreground the company's mill and log pond. The equipment of the mill includes two 8 feet bands and one 8 feet resaw. The capacity is about 120,000 feet per day on single shift, cutting spruce and hemlock exclusively. This mill has used Disston Saws for a number of years back. The company owns a pulp and paper mill at Richwood, which also appears in the pictures. This plant is supplied almost entirely by the offal of slabs from the saw mill. The company's lumber yard is shown in the extreme right. The athletic field which is seen in the view of the town is sustained by the various companies now located at Richwood. Another Richwood concern is the Dodge Clothespin Company also loyal rooters for Disston quality. It is interesting to know that this is one of the largest factories in the world producing clothespins. However, this is not their exclusive line, as they are also large manufacturers of wooden veneered trays. band saws are used throughout. They are also large users of Disston small circular saws, veneer and special knives. They say that Disston spells satisfaction to them. Disston |
