Overview
This lecture explains the difference between hand tools and power tools, highlights common hand tools, and focuses on important safety practices when using hand tools in the woodshop.
Hand Tools vs. Power Tools
- Hand tools are powered by your body, not motors, electricity, or other external sources.
- Power tools are powered by external sources like electricity, gas, or air, even if you hold them in your hands.
- Both hand tools and power tools can be dangerous if not used correctly.
Common Hand Tools in the Woodshop
- Frequently used hand tools include screwdrivers, hammers, chisels, rasps, hand planes, and handsaws.
- Each tool has a specific purpose; using the wrong tool can be unsafe.
Hand Tool Safety Practices
- Always wear safety glasses, even when using hand tools.
- Clamp your workpiece securely to prevent it from moving during use.
- Use the correct tool for the job (e.g., paint scraper for glue, not a chisel).
- Never force a tool or overload it; forcing increases accident risk.
- Avoid cutting or pushing tools toward your body or hands.
- Always keep two hands on the tool when possible for better control.
- Be aware of your body's position relative to the tool to minimize injury risks.
- For screwdrivers, keep hands clear of the tool's path to avoid stabbing injuries.
- When using a hammer, hold the nail with the non-hammering hand and remove that hand after starting the nail.
- Always watch the nail when hammering, and use the hammer’s claw only for pulling out nails.
