Book excerpt: Excerpt from The B. T.& B. Manual: A Treatise on the Care of Saws and Knives While there is no universal method for the fitting of saws and knives, there is a sort of common ground where all filers can meet and harmonize, and while one man may question the merit of the method of another, he does not necessarily need to feel that such method is an impracticable or an unsuccessful one. We are indifferent whether the matter presented is always in line with the readers experience or practice and shall anticipate that there may be some statements made that will be challenged. But if criticism and discussion amongst filers shall result, if they shall be set to thinking and talking, something of good will surely follow. We are indebted to writers in The Woodworker (published by S. H. Smith Co., Indianapolis, Indiana, ) for many practical suggestions, and we cannot give better advice to any saw filer than to become a subscriber to that journal. We are also indebted for some illustrative cuts and special matter to W. B. Mershon & Co., E. C. Atkins & Co., Henry Disston & Sons, A. J. Burton, J. H. Miner, N E. Huff, E. L. Mason, N. L. Botten, J. D. Gebott, and others. Dont's For Millmen Don't keep poor men about you or allow such to experiment upon your saws. Don't maintain a small, vibrating and dimly lighted filing room and expect your saws to be well fitted. Don't think that hand fitting of saws or knives can discount machine fitting, unless you are indifferent to profits. Don't buy any filing room machines on the single ground of cheapness. Facilities of the manufacturer, known quality of his product, evident disposition to give value received, efficiency acknowledged by users, perfect fit and finish, abundant weight and strength and consequent rigidity - these are the elements that govern intelligent and exacting buyers. Don't refuse your filers good equipment if you value fine results. Don't be afraid to scrap machines because they are not worn out. Don't refuse to pay good filers good wages; they make money for you and are the only kind you can afford to have around. Great business to keep 50 to 100 men waiting on the saws 5 to 30 minutes a day because of poor saw fitting. Don't order a cheap machine in preference to one higher priced. Unwise economy is another name for foolish prodigality. Consider whether a temporary saving will be a permanent one. It is literally true that concerns frequently fail in business because of poor equipment. They cant manufacture as cheaply as better equipped competitors who spread their fixed charges over a much greater and better manufactured output, and make money every day the wheels turn round. Don't figure that the first cost of a machine or tool is its final cost. Will it last and stand up without continual repairs? Will it be efficient in six months or a year or five years? Every mill has plenty of poor machines that are scrapped soon after purchase or that are continued in use because on hand, but at a direct positive loss. How many such have you? Don't conclude that a filer who asks you for a better machine or an additional machine is your natural enemy. He gets no rake-off. He is simply seeking for better results, or to save time, or to preserve the life and efficiency of the saws or knives. Give him proper credit for honesty and industry and intelligence. Don't try to run a sawmill with inconstant or insufficient power. Don't suffer your carriage to be out of proper alignment with the saw. Don't run band wheels with faces out of true. Don't tolerate a carriage track that is neither level nor straight or a sprung mandrel or lost motion in boxes or end play in arbor or trucks, or weak and imperfect collars and pins or guide pins. Don't buy saws too thin or too thick. You will need to make some saw dust, but this need not be your specialty. Don't
