COLOR: Heartwood is creamy white to light reddish brown; sapwood is pale to creamy white.
GRAIN: Closed, subdued grain, with medium figuring and uniform texture. Occasionally shows quilted, fiddleback, curly or bird's-eye figuring. Figured boards often culled during grading and sold at a premium.
VARIATIONS WITHIN SPECIES AND GRADES: Black maple (B. nigrum) is also hard; other species are classified as soft.
HARDNESS (JANKA): 1450 (12% harder than Northern red oak).
DIMENSIONAL STABILITY: Average (9.9; 15% less stable than red oak).
SAWING/MACHINING: Density makes machining difficult.
NAILING: No known problems.
SANDING: Extra care must be taken during sanding and finishing, as sanding marks and finish lines are more obvious due to maple's density and light color. The species also burnishes, dulling fine paper and screens and making it difficult to cut out previous
Suggested Sequence First Cut: 50 at a 7 to 15 degree angle to the grain
Second Cut: 80 straight with the grain
Third Cut: 120
Hard Plate: 100 or 120
First Screen: 100
Second Screen: 100
FINISHING: Takes neutral finish well. May be difficult to stain.
Origin North America.
