Moulding & Shop Grades

29 mm & Thicker RWL Moulding Stock
Ponderosa Pine

Moulding Stock is suitable for ripping into strips 25 mm and wider, 3.0 m and longer. At least 66.7 % of the area contains such rips of the grade permissible in standard mouldings. In 29, 36 and 40 mm wide Moulding Stock, the grade of each rip is determined from the poorest face. Wane, stain, skips in dressing or other characteristics that will surface off in making mouldings are permitted in computing the percentage of rips. Up to 10% of the total cubic metres of any item may be 1.8 to 2.7 m, provided each piece contains 66.7% or more of full length Moulding Rips.

Both pieces are 4.9 metres long.

Example 1 is 152 mm wide and contains 83.8% of acceptable Moulding Rips. Rip is 127 mm x 4.9 m.

Example 2 contains 76.2% of acceptable Moulding Rips. The scale-off mark (which is the circled numeral 1 in the board) indicates that 0.09 m2 surface measure is “scaled off” due to wane creating a total loss of 10% or more of the area of the piece. Rips are 32 mm x 4.9 m, 32 mm x 4.6 m, 44 mm x 4.3 m, 44 mm x 3.7 m, and 38 mm x 3 m.

Example 1 is 378 mm wide and scales 1.9 m² surface measure. The total area of acceptable Door Cuttings is 1.05 m², or 55.3%. Cuttings are two at 229 x 914 mm, 229 x 711 mm and 229 x 762 mm.
