This historic book may have numerous typos and missing text. Purchasers can usually download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1907 edition. Excerpt: ...and 7$ on the other, but either of the squares gives the same result as far as the miter is concerned. The following is another article by Mr. Woods on bevels and hopper cuts generally, which owing to its excellency, we have thought worthy of a place in this work. The author starts out by saying: If there was no given pitch, then the sides would be vertical. Now with 12 on the tongue as center, draw arc of same radius from the heel to a point directly above and square over the blade; 12 and 12 will give the miter, Fig. 74. Simple enough, but do you know that this simple rule applies when there is a pitch given? At the point where the arc intersects the pitch taken on the blade will give the miter, the blade giving the cut. See Fig. 75. For the side bevel across the board, transfer the length of the pitch to the blade, the tongue giving the cut. These figures also give the side cut of the jacks for a roof of same pitch. The blade in this case giving the cut. Now we will give another method of finding the miter. In all roofs and hoppers there is an unseen pitch which we will call co-pitch. Assuming that the edges of our board are square the co-pitch would stand at an angle of 90 degrees with the given pitch. See Fig. 76. The rule given in Fig. 75 for the side bevel will apply to the miter, but instead of using the length of the given pitch substitute that of the co-pitch, and by referring to Fig. 76 we find this to be 15f inches on the blade. Now for proof, see Fig. 77. Twelve and 9 first method, and 12 and 15 second method. The blade giving the cut in the former, and the. tongue in.the latter. In Fig. 78 is shown all that is contained in the other figures, besides showing another pitch. It is an extension of the co-pitch to a point of the...
