Woodworking Wood Types And Properties 2

Question 1

What does the moisture content (MC) of wood refer to?

Accepted Answer

The weight of water in wood expressed as a percentage of its oven-dry weight

Answer

Moisture content is the weight of water in a piece of wood expressed as a percentage of its oven-dry weight, and it affects stability and workability.

Question 2

What is 'heartwood'?

Accepted Answer

The dense, darker inner core of a tree

Answer

Heartwood is the older, denser inner wood of a tree, typically darker and more resistant to decay than the surrounding sapwood.

Question 3

Which wood is most commonly used for kitchen cutting boards due to its tight grain?

Accepted Answer

Maple

Answer

Hard maple has a very tight, closed grain that resists bacteria and moisture absorption, making it the preferred choice for cutting boards.

Question 4

What causes knots in lumber?

Accepted Answer

Branch stubs that were surrounded by the growing trunk

Answer

Knots form where branches once grew from the trunk, and as the tree continued to grow, the branch stub was encased within the expanding wood.

Question 5

What is the primary difference between quarter-sawn and flat-sawn lumber?

Accepted Answer

Quarter-sawn lumber has growth rings nearly perpendicular to the face, making it more stable

Answer

Quarter-sawn lumber is cut so the growth rings are roughly perpendicular to the board face, resulting in greater dimensional stability and a distinctive ray fleck pattern.
