1. True or False: The terms "growth rings" and "grain" refer to the same anatomical feature of wood.

True

False

The terms "growth rings" and "grain" both refer to the same anatomical feature of wood. Growth rings are the concentric circles that can be seen when a tree is cut, indicating the annual growth of the tree. Grain, on the other hand, refers to the direction, size, and arrangement of the wood fibers. Both terms are used to describe the characteristics and appearance of wood.

2. Why does the hook on the end of a tape measure move back and forth?

To account for the thickness of a pencil mark

To account for the thickness of the hook

To account for making inside or outside measurements

Both B and C

The hook on the end of a tape measure moves back and forth to account for the thickness of the hook itself and to account for making inside or outside measurements. The hook is typically thicker than the body of the tape measure, so when measuring against a surface, the hook needs to move to ensure accurate measurements. Additionally, when measuring inside or outside dimensions, the hook needs to move to accommodate for the added thickness of the tape measure body. Therefore, both options B and C are correct.

4. Who introduced Norm Abram to hand tools as a boy?

His father

His high school shop teacher

His uncle

His brother

5. How many loops will an average band saw blade make when you coil it up for storage?

Two

Four

Five

Three

When you coil up a band saw blade for storage, it will make three loops. This is because the blade needs to be folded in a specific way to ensure it remains compact and doesn't get tangled. By creating three loops, the blade can be neatly stored without any risk of damage or entanglement.

6. True or false: Softwoods splotch when stained because the latewood is softer than the earlywood.

True

False

Just the opposite is true; earlywood bands are softer and less dense than the latewood bands, so they absorb more stain.

Explanation

Just the opposite is true; earlywood bands are softer and less dense than the latewood bands, so they absorb more stain.

7. Which of the following is the best lubricant for French polishing:

Canola oil

Mineral oil

Denatured alcohol

Tung oil

Mineral oil is the best lubricant for French polishing because it is a clear, odorless, and non-drying oil that does not leave any residue. It provides a smooth and even finish on wood surfaces, enhancing the shine and depth of the polish. Canola oil and tung oil are not commonly used for French polishing, as they may leave a sticky residue or require longer drying times. Denatured alcohol is used as a solvent in French polishing, but it is not a lubricant.
