LAMONT, Secretary of Commerce, chairman. R. Y. STUART, Forester, United States Forest Service, Department of Agriculture, vice chairman. AXEL H. OXHOLM, director. The National Committee on Wood Utilization, organized by Herbert Hoover, as Secretary of Commerce, comprises about 200 members, representing manufacturers, distributors, and consumers of forest products. Its object is to work for closer utilization of our country's timber resources. The committee, whose headquarters are in the Department of Commerce, Washington, D. C., works in close cooperation with a number of official and private organizations, notably the Bureau of Standards of the Department of Commerce and the Forest Products Laboratory of the Forest Service, Department of Agriculture. SUBCOMMITTEE ON GANG SAWING OF LUMBER A. TRIESCHMANN, Crossett Watzek Gates, Chicago, Ill., chairman. F. W. REIMERS, general manager Natalbany Lumber Co., Hammond, La. FOREWORD Constantly changing conditions as to the character of our timber supplies, the cost of raw material, and varying labor conditions necessitate corresponding changes in sawmill and woodworking equipment in order to effect the closest possible utilization of wood. The National Committee on Wood Utilization is following developments in the woodworking machinery field both at home and abroad, and from time to time conducts practical tests of sawmill and woodworking equipment. For this reason it has taken the initiative in testing the Scandinavian gang saws in this country, which for decades have been in successful operation abroad, where the urge for closer wood utilization has been more strongly felt than it is in America. The National Committee on Wood Utilization expresses its appreciation of the valuable assistance given by the Tumwater Lumber Mills Co. (Inc.), Olympia, Wash., which declared its willingness to install these machines in its plant, permitting the committee to test them. The committee is also indebted to Svenska Maskinverken, Sodertalje, Sweden, and its associates J. & A. Jensen og Dahl, Oslo, Norway, and Karlstad Mekaniska Verkstad, Karlstad, Sweden, the producers of the gang saws which were tested. The favorable terms upon which their machines were offered to American sawmill operators for test purposes were largely responsible for the committee's ability to carry out its project. Acknowledgment is also made to the Mill Engineering & Supply Co., of Seattle, Wash., which has assisted the committee in the preparation of drawings, illustrations, and other useful dnata necessary in compiling this report, and to Roy F. Morse, general manager, Long-Bell Lumber Co., Longview, Wash., for his efforts in testing the gang saws. OCTOBER 7, 1929. AXEL H. OXHOLM, Director. |
