Crafting Woodworking and Mixed Media 3 — Questions and Answers
Question 1: What is 'kerf' in relation to a saw?
- The width of material removed by the blade (Correct answer)
- The handle of the saw
- The angle of the cut
- The teeth count per inch
Correct answer: The width of material removed by the blade
Kerf is the slot width the blade cuts, which must be accounted for in precise measurements.
Question 2: Which tool is best suited for cutting curved shapes in thin plywood?
- Jigsaw or scroll saw (Correct answer)
- Table saw
- Hand plane
- Chisel
Correct answer: Jigsaw or scroll saw
A jigsaw or scroll saw uses a narrow blade that can follow curves easily.
Question 3: In mixed media, what is 'gesso' commonly used for?
- Priming a surface to improve paint adhesion (Correct answer)
- Cutting wood
- Removing rust
- Softening leather
Correct answer: Priming a surface to improve paint adhesion
Gesso seals and primes the substrate so paints and media bond well.
Question 4: Why should you drill a pilot hole before driving a screw into hardwood?
- To prevent the wood from splitting (Correct answer)
- To make the screw rust
- To weaken the joint
- To remove the need for a screwdriver
Correct answer: To prevent the wood from splitting
A pilot hole relieves pressure so the dense wood doesn't crack when the screw is driven.
Question 5: What does 'grit' refer to on sandpaper?
- The coarseness of the abrasive particles (Correct answer)
- The color of the paper
- The width of the sheet
- The glue strength
Correct answer: The coarseness of the abrasive particles
Grit numbers indicate particle size; lower numbers are coarser and higher numbers are finer.
Question 6: When embedding found objects in resin over a wood base, what is a common problem to avoid?
- Trapped air bubbles around the objects (Correct answer)
- Too much wood grain
- Excess sanding dust
- Overly bright colors
Correct answer: Trapped air bubbles around the objects
Air bubbles can form around embedded items and mar the clear finish if not released.
Question 7: Which wood movement is greatest as humidity changes?
- Across the grain (width) (Correct answer)
- Along the grain (length)
- Only diagonally
- Wood does not move at all
Correct answer: Across the grain (width)
Wood expands and contracts far more across its width than along its length.
