Crafting Woodworking and Mixed Media 2 — Questions and Answers
Question 1: When gluing two boards edge to edge, why should the wood grain run in the same direction?
- To match seasonal wood movement and prevent joint failure (Correct answer)
- To make the boards heavier
- To change the wood color
- To remove the need for clamps
Correct answer: To match seasonal wood movement and prevent joint failure
Aligning grain lets both boards expand and contract together, avoiding stress that cracks the glue joint.
Question 2: What is the main purpose of a jig in woodworking?
- To hold or guide a tool for repeatable, accurate cuts (Correct answer)
- To sharpen chisels
- To finish surfaces with oil
- To measure moisture content
Correct answer: To hold or guide a tool for repeatable, accurate cuts
A jig guides the workpiece or tool so identical operations can be repeated precisely.
Question 3: In mixed media art, what does the term 'substrate' refer to?
- The base surface on which the artwork is built (Correct answer)
- The final protective varnish
- A type of acrylic paint
- The frame around the piece
Correct answer: The base surface on which the artwork is built
The substrate is the foundational surface, such as wood panel or canvas, that supports the layered materials.
Question 4: Which finish is best when you want to keep a wood surface food-safe for a cutting board?
- Food-grade mineral oil (Correct answer)
- Polyurethane spray
- Oil-based enamel paint
- Shellac with alcohol
Correct answer: Food-grade mineral oil
Food-grade mineral oil is non-toxic and safe for surfaces that contact food.
Question 5: Why is a mortise-and-tenon joint valued in furniture making?
- It provides a strong, long-lasting mechanical connection (Correct answer)
- It requires no wood at all
- It is only decorative
- It weakens over time faster than screws
Correct answer: It provides a strong, long-lasting mechanical connection
The interlocking peg-and-socket design gives excellent strength and durability for frames and joints.
Question 6: When incorporating metal leaf into a mixed media wood piece, what is typically applied first?
- A tacky adhesive size (Correct answer)
- Water
- Sawdust
- Wax
Correct answer: A tacky adhesive size
Gilding size is an adhesive that becomes tacky, allowing the delicate metal leaf to stick.
Question 7: What safety step is essential before sanding old painted wood that may contain lead?
- Test for lead and use proper containment and respiratory protection (Correct answer)
- Sand faster to finish quickly
- Wet the wood with paint thinner
- Skip the mask if working outside
Correct answer: Test for lead and use proper containment and respiratory protection
Lead paint dust is hazardous, so testing and using protection prevents dangerous exposure.
