Furniture, cabinets, decorative trim |
| Engineered Wood (plywood, MDF, particleboard, OSB) |
Stable, uniform, often cheaper |
Sub‑floors, sheathing, interior panels |
| Composite Decking |
Weather‑resistant, low maintenance |
Outdoor decks, railings |
4. Essential Hand Tools
| Tool |
Purpose |
Tips for Use |
| Tape Measure |
Accurate length measurement |
Keep the blade flat; lock for consistent readings |
| Combination Square |
Marking 90° and 45° lines; checking depth |
Use the steel rule for fine markings |
| Marking Gauge |
Scribing parallel lines |
Set depth to material thickness for consistent cuts |
| Coping Saw |
Cutting curves & coping mouldings |
Use fine‑toothed blades for smoother cuts |
| **Chisels (bench, mortise) ** |
Removing waste wood, shaping joints |
Keep edges sharp; tap with a mallet, not a hammer |
| Hand Plane |
Flattening, smoothing, trimming |
Adjust mouth opening for fine vs. rough work |
| Claw Hammer |
Driving nails, extracting them |
Choose weight (16‑20 oz) for balance |
5. Essential Power Tools
| Tool |
Primary Function |
Safety Highlights |
| Circular Saw |
Straight cuts in sheet goods, lumber |

| Table Saw |
Precise rip cuts, cross‑cuts, dadoes |
Use a riving knife, blade guard, and push stick |
| Miter Saw |
Angled cross‑cuts, miters, bevels |
Keep blade guard closed; never reach over blade |
| Jig Saw |
Curved cuts in thin material |
Use the correct blade for wood vs. metal |
| Router |
Shaping edges, creating dados, decorative profiles |
Use a router table for stability; wear a push block |
| Random‑Orbit Sander |
Surface sanding, smoothing edges |
Keep dust extraction on; avoid excessive pressure |
