Lam-Loc pecky cedar is a natural lumber product from the California and Oregon high country. Its peck is the result of a fungus growth which stops the moment the tree is felled. Northwest lncense Cedar is among the world's most durable woods and ranks with redwood in its dimensional stability, resistance to decay and paint holding characteristics.

The patented Lam-Loc process makes the cedar easier to handle and eliminates any through-pecks which are found in the natural product. It is available in B', LU,12l widths s/o" thick, in specified lengths to 16r.

Plywood Gussel Trusses Rote Besl

Trusses fabricated with nail-glued plywood gussets are stronger and stifier than metal-gusset trusses, with less deflection under loads, according to the final report of a Michigan State University study conducted recently.

The tests were conducted to determine the load versus deflection characteristics of full-size trusses. (Trusses used for the tests were 26-foot-span W trusses with a 3/I2 pitch.)

Results of the tests showed creep deflection of the plywood-gusset trusses was negligible. In two of the metal-gusset trusses there was a 20 percent deflection, the third metal-gusset truss had a 15 percent deflection under the same loads.

Trusses built with plywood gussets proved to be considerably stronger and stiffer than the metal-gusset trusses. For purposes of comparison, plywood-gusset trusses were rated at 100 percent in strength and stifiness. On that basis, the other three trusses were rated at 73,73 and 57 percent for strength; all three were rated at 42 percent for stiffness.

All 2 x 4 lumber members in the trusses were nondestructively tested to establish their stifiness factors.

Plywood gussets used in the tests were 3f inches thick, nailed with 4d common nails on 4-inch centers and glued with casein glue.

Two of the metal gusset plates were .040-inch thick steel sheet and the third was .037-inch-thick steel sheet.

The Michigan State University formal laboratory report is entitled 'oEffect of Variables on Performance of Trussed Rafters.'o A booklet describing various types of plywood-gusset truss designs similar to those tested by MSU is available by writing to American Plywood Association" Tacoma.

WWPA Tops District Directors

Western Wood Products Association's District B, cornprising middle and southern California and Nevada, elected new of. ficers and discussed major industry problems at a Sacramento meeting, January 25.

New officers are: Grant B. Potter, Sequoia Forest Industries, chairman; George Duff, Cal-Ida Lumber Co., vice chairman, and F. M. Crawford, F. M. Crawford Lumber, Inc., secretary. C. T. Gray, American Forest Products Corp., and H. C. Setzer of Setzer Forest Products, Inc.. who will represent the district on the WWPA board of directors.

Moterials Firm Closes

L. A. Material and Supply Co., southern California building material dealer firm for decades, has closed its' doors.

Andrew E. Crowell, company president, asserted, 'oL. A. Material and Supply Company commenced a complete liquidation of its business and in due course will dissolve its corporate existence. Our retirement from the building material supply business is entirely voluntary."

It is expected that a new corporation to be named L.A. Building Material Co., headed by two of the prior firm's employees, Vayne Blackstock and Merle Swanson, will take over any of the job commitments.
