Western Red Cedar for NPS Park Identity Signs:

WRC for NPS Park Identity signs shall be laminated clear heart, kiln-dried vertical grain with a maximum moisture content not to exceed 12%. Cedar shall be selected per grading rules of the Western Red Cedar Lumber Associa-tion. Components of all panels including end caps shall be fabricated from the same grade.

Panel Size:

Sign panel shall be fabricated based on dimensions and format specified in the Sign Drawing Package. Panel sizes, specifications, dimensions, typography, color, and proportions shall not be altered.

Panel Assembly:

Panels shall be constructed using clear heart, vertical grain, kiln-dried wood through, glued up one board thick using 2" nominal size dimensional lumber (2" x 6", 2" x 8", 2" x 10"). Panels shall be glued using a phenolic resorcinol moisture resistant adhesive with all surface joints covered. Panels shall be clamped and cured for a minimum of 24 hours or per the manufacturers specifica-tions. Panel fabrication shall occur in air temperatures between 70 and 90 degrees Fahrenheit during drying, adhesive application, and curing.

After curing the panel vertical edges shall be finished with a 2" x 2" vertical end strip, faced glued and reinforced with 3", No 12 stainless steel Phillips flathead screws placed 8" on center. Screw heads shall be counter-sunk to a depth of 3/8" and filled with glue-in wood plugs.

After end strips have cured the panels shall be machine planed to a finish thickness of 1-1/2". All surfaces shall be finish sanded smooth and face and back edges shall rounded to a radius of 1/8".

Panels shall not be finished with hand planes, hand-held belt, orbital, or vibrating sanders.

Graphic Layout:

Routed letters shall conform to the same size artwork. Routing depth shall be uniform. Corners of type smaller than 3" cap height shall have a radius no greater than 0.0625. Type larger than 3" cap height shall have a corner radius no greater than 0.125".

Frutiger Bold typography shall be Machine-routed unless otherwise specified using a vertical-sided, flat-bottom router bit. Routing depth to be 0.375".

Vertical dados shall be routed to a depth of 0.250".
