8/16/2023 0 Comments Sugar maple woodUnfortunately, there is no definition of “how white is white” so different suppliers will have different whiteness. The bending strength is 15,800 psi, stiffness 1.83 million psi and hardness is 1450 pounds. Sugar maple is a little (10 percent) stronger, stiffer and harder than black maple. Hard maple changes width and thickness when the RH changes.about 1 percent size change running parallel with the rings (tangentially) when there is a 3 percent MC change, and 1 percent change across the rings (radially) when there is a 6 percent MC change. Avoid over-drying the lumber (under 5.5 percent MC is over-dried), as brittleness and poor machining will be increased. To avoid chip out and torn grain, knives must be very sharp. Because the grain in maple swirls quite a bit, planing and other machining operations will frequently be planing against the grain. ![]() Small errors will result in low strength joints. Maple requires surfaces to be glued to be freshly prepared and perfectly flat. For most uses, 6.5 percent MC is the ideal final target, with almost all pieces being within + or – 1 percent MC. Moisture content when the lumber leaves the kiln must be very close to the in-use moisture content. For whitest color, maple must be stacked promptly after sawing using dry stickers. Chemical staining occurs when the starches and sugars oxidize to pink or gray colors. Maple is subject to blue staining and also chemical staining if not dried promptly and aggressively. Processing suggestions and characteristicsĪfter drying to 7 percent MC and planing to 13/16 inch, maple weighs 3-1/3 pounds per board foot. Also, did you know that it takes about 40 gallons of sap to make a gallon of syrup? A grove of producing sugar maple trees is called the sugar bush. What person hasn’t had pancakes topped with wonderful, sweet maple syrup? Sugar maple is the tree that produces maple syrup. ![]() The name “hard” actually means that the lumber is substantially harder than the other maples, including the grouping called soft maple. Once hard maple lumber is manufactured, it is impossible, even under magnification, to separate the lumber into the two individual species. Most lumber comes from sugar maple (Acer saccharum) and a small amount from black maple ( Acer nigrum). Hard maple lumber, which is also called sugar maple, sweet maple, black maple and rock maple, comes from two species. What is this ubiquitous wood that we call maple? Uses include cabinets, furniture, bowls, bowling alleys, bowling pins, flooring, piano frames, dulcimers, spinning wheels, cutting boards, tool handles, veneer, pallets, particleboard, paper, firewood, and even railroad ties. Hard maple is a wonderful, expensive, nearly white wood used for almost every application imaginable both today and even prior to the colonization of the U.S.
