Wood Types

The species of wood, as well as its condition, has a dramatic effect on the depth of cut the planer can effectively take with each pass. The harder the wood (as illustrated by its shear strength), the shallower the depth of cut should be.

Commonly used hardwoods and their associated shear strengths are illustrated in Figure 12.

		Type	Shear (PSI)
		Black Locust		2,480
		Sugar Maple		2,330
Increasing	Difficulty	Pecan Hickory		2,080
		American Elm		1,510
		White Oak		2,000
		White Ash		1,950
		Black Cherry		1,700
		Black Walnut		1,370
		Red Alder		1,080
		Basswood		980
		Cottonwood		930
