Woodworking Honor

Arts & Crafts

Requirements

1. Identify at least 5 common types of wood, such as: pine, peroba, mahogany, massaranduba, and rosewood (jacaranda).

   Answer: You identify: 1) Pine — light-colored, lightweight, easy to work with (simple furniture); 2) Peroba — yellowish-pink, hard, durable (structures, furniture); 3) Mahogany — reddish-brown, fine wood, easy to polish (instruments, fine furniture); 4) Massaranduba — dark red, very hard (decks, beams); 5) Rosewood (jacaranda) — dark, almost black, fine, fragrant (musical instruments, luxury furniture). — Brazilian mahogany and rosewood are listed under CITES (international protection) — their exploitation is restricted. Massaranduba is one of the densest (1,100 kg/m³ — it sinks in water). Imported pine is the most used in civil construction because of its availability. Each wood has a characteristic 'smell' — rosewood is especially fragrant.

2. Know the characteristics of the woods identified and know at least one use for each example given.

   Answer: You describe: Pine — light-colored, lightweight, soft, easy to work with (use: simple furniture and construction). Peroba — hard, durable, yellowish (use: beams and structures). Mahogany — reddish-brown, fine texture (use: fine furniture and instruments). Massaranduba — dark red, very dense (use: outdoor decks). Rosewood — black, fragrant (use: guitars and fine furniture). — Wood density (kg/m³) predicts hardness: pine 500, peroba 800, mahogany 600, massaranduba 1,100, rosewood 900. Dense woods last for decades in outdoor use. Mahogany is exported in pieces such as luxury-yacht trim. Bahia rosewood is banned from export by CITES — to protect the species.

3. What are the differences between conifers and broadleaf (hardwood) trees? Does this classification indicate which species are better for woodworking? Justify your answer.

   Answer: You distinguish them: Conifers (gymnosperms) — pines, cypresses, seeds in cones, needle-shaped leaves, generally soft wood; Broadleaf trees (angiosperms) — eucalyptus, oak, mahogany, ipê, seeds in fruits, broad leaves, generally hard wood. The classification does NOT indicate quality — it depends on the use. Conifers (pine) are good for construction; broadleaf trees (mahogany) are good for fine furniture. — 'Softwood' (conifers) and 'hardwood' (broadleaf trees) are botanical terms, not absolutes. There are hard conifers (yew) and soft broadleaf trees (balsa). Ipê (a Brazilian hardwood) is one of the hardest woods in the world. For woodworking, choose according to use: pine for beginners; mahogany for fine finishing.

4. Know how to properly use the following tools in woodworking:
   • Jigsaw
   • File or rasp
   • Plane
   • Knife
   • Cold chisel/wood chisel
   • Sandpaper

   Answer: 1) Jigsaw: cuts curves and irregular shapes with a thin blade in an alternating vertical motion; guide the saw slowly, following the marked line, and hold the piece steady. 2) File or rasp: smooths down and trues wood surfaces; work with straight forward strokes, without dragging back, going from the roughest to the smoothest part (the rasp is coarser, the file gives the finish). 3) Plane: smooths and levels the wood by removing thin shavings; push in long, regular strokes in the direction of the grain, keeping the blade sharp and well adjusted. 4) Knife: used for carving and trimming; always cut at a safe angle, with the blade going away from your body and hands. 5) Chisel/gouge: removes pieces and makes joints; place the cutting edge on the wood and strike the handle with a hammer or mallet, cutting in the direction of the grain. 6) Sandpaper: gives the final finish after cutting; sand in the direction of the grain, starting with coarse grit and finishing with fine grit to leave the surface smooth. — Each tool has a specific technique that requires practice. The jigsaw is good for beginners (safe). The plane is difficult — its sharp blade needs to be well adjusted. Sandpaper follows an order: 80, 120, 220 (coarse → fine). The knife is the most dangerous in untrained hands — always cut away from your body, holding the piece firmly.

5. Know at least 2 safety procedures for each of the tools above.

   Answer: You know: Jigsaw — keep hair/loose clothing away + wear protective goggles. File — hold both ends firmly + never push toward your body. Plane — support the piece firmly + never touch the exposed blade. Knife — always cut away from your body + keep your free hand behind the blade. — Woodworking accidents are most often caused by carelessness (90% according to the INSS): hair caught in the saw is serious. Protective goggles are mandatory for any cutting. Knife work requires the 'thumb away' technique (thumb on the opposite side of the blade). Mahogany dust is carcinogenic (IARC Group 1) — a mask is vital during long cuts.

6. Cut, assemble, and finish a bookend or a doorstop.

   Answer: You cut the pieces (bookend: 2 sides + 1 base; doorstop: a single piece in a decorative shape). Assemble it with wood glue + small screws or finishing nails. Sand from 80 to 220 grit for a smooth surface. Apply a finish: matte varnish for indoor use, or paint. Present the finished piece to the instructor for evaluation. — Simple bookends have 3 parts at a 90° angle: 2 vertical sides + 1 base. Wood glue (PVA) + screws = a stronger joint than nails. Sanding before applying varnish is vital — dust hampers adhesion. Matte varnish is simpler for beginners (it does not show defects the way glossy does). The finished piece becomes a useful gift.

7. Carve and finish a garden stake or a lawn sign, giving it some shape, such as that of a child, bird, flower, or tree.

   Answer: You choose a shape (bird, flower, child, tree), draw the outline on the wood with a pencil, cut with a jigsaw following the outline, refine the details with a chisel and knife, sand in sequence (80, 120, 220), and apply varnish for outdoor use (rain-resistant). Present the finished stake/sign to the instructor for evaluation. — Outdoor varnish is different from indoor varnish: it contains UV protectors and is more flexible to withstand temperature variation. Pine impregnated with copper lasts 5+ years in moist soil; cedar 10+ years. Stakes/signs become useful gifts for gardens and for labeling beds — a project that combines usefulness and art with wood.

8. Make a plaque, a tray, or some other useful object in which wood is used.

   Answer: You choose among a plaque, a tray, or a useful object (catch-all tray, coasters, pen holder). Define the dimensions, cut the wood (pine or plywood), assemble it with wood glue + screws, sand from grit 80, 120, and 220, and apply a finish (varnish, tung oil, or paint). Document the process with photos of the steps and present the finished object to the instructor. — Trays require sides (3-5 cm high) to keep their contents from falling off. Pine is the ideal wood for beginners (it is inexpensive and easy to cut). Tung oil is a natural, food-safe finish — good for trays that carry food. Woodworking as a hobby became popular after the pandemic, with a 200% increase in tools sold in Brazil.
