CANADA LUMBERMAN AND WOODWORKER Methods of Quarter Sawing Oak Plans Adopted by an Experienced Sawyer—Compar- isons of Results Secured by Two Different Methods There are scarcely two experts on the quarter-sawing of oak logs who will agree exactly as to the best methods of sawing. The head of one large oak-manufacturing institution has made repeated tests of various systems, and has repeatedly employed the methods illustrated in the two diagrams accompanying this article, says the Hardwood Record. In the method illustrated in Figure No. 1 the log is split one side of the heart, and the minor portion dropped onto the log deck. Pour to seven or eight boards are then cut through the centre of the tog; the half section is again split in halves, and the quarter thrown onto the deck. The remaining quarter is then sawn;'then the half section is split and the same process ensues. Many advocates of this system contend that a larger amount of wide stock, and less waste results than by any other means. In the second method, illustrated in Figure 2, the log is split. METHOD NO. 1. METHOD NO. 2. absolutely in the centre and the half dropped onto the log deck and each half is sawn without removal from the carriage. The gentleman referred to has made repeated tests of these two methods and his deduction is that method No. 2 affords the best net residt in quality and economy of time in sawing. These results are indicated in the following tables and show very closely what has been achieved in scores of tests. It will be noted that the prices shown are* lower than the present average values on quarter-sawed stock, but the comparison is just as valuable: Method No. 1. Log 12 ft. long, 43 in. diameter, containing 1,046 ft. Lumber cut 810 ft. Loss, 23 6 ft. 1 and 2—58 pes., aver. in., 689 ft. at $75 85% No. 1 com.—15 pes., aver. in., 95 ft.
