What are wooden hand tools ?
Wooden Hand Tools are tools that are used by woodworkers like carvers or carpenters to make their work easier, faster and neater . Most of these these tools have metallic iron blades and wooden handles . Wooden Hand tools are held by hands when in used by carvers or carpenters
Woodworking hand tools are tools that are used by hand, rather than powered by electricity. Some examples of woodworking hand tools include:
- Chisels: used for cutting and shaping wood
- Hammers: used for driving nails and shaping metal
- Handsaws: used for cutting wood
- Planes: used for smoothing and shaping wood
- Screwdrivers: used for driving screws
- Spokeshaves: used for shaping and smoothing wood
- Hand drills: used for drilling holes
- Files: used for smoothing and shaping metal and wood
Types of Wooden Hand Tools
Wooden hand tools are classified and grouped specifically based on how they are used which are
- Measuring and Marking tools ( Geometric tools )
- Holding and Supporting wooden tools
- Cutting tools
- Percussion tools
Measuring and Marking tools ( Geometric tools )
These are tools that are used by professionals like carvers , carpenters ,scientists or teachers to measure , mark ,or take dimension of length , breadth , width or thickness of materials like wood before they start working on that wood.
Examples of such wooden measuring and marking tools are
- Pencils
- Marker
- Compass.
- Ruler.
- Protractor.
- Divider.
- Set-squares.
- Tee square
- Marking knife
- Tape rule
Holding and Supporting wooden tools
These are tools that are used by wood workers to grasp or hold on to wood material firmly when they are working in the workshop . Examples of Holding and Supporting wooden tools are
- G clamp
- F clamp
- Hand Screw
- Carpenter vice
- Racket Brace
Wooden Cutting tools
These wooden hand tools are used for cutting . Examples are
- hand saw
- cross cutter saw
- wood drilling bit
- chisel
- smoothing plane
- router
- utility knives
- carving knives
Percussion tools
These are tools that are used to drill or drive in nails into wood . Examples are
- Hammer
- mallet
- screw driver
- spanner
- nail punch
- hand drill
Measuring and marking hand tools, also known as geometric tools, are tools used for measuring and marking out workpieces in woodworking and other crafts. Some examples of measuring and marking hand tools include:
- Measuring tapes: used for taking linear measurements
- Rules: used for taking linear measurements
- Squares: used for marking and checking for squareness
- Bevel gauges: used for transferring and marking angles
- Protractors: used for measuring and marking angles
- Calipers: used for taking precise linear measurements
- Micrometers: used for taking very precise linear measurements
- Scribes: used for marking lines on workpiece
Comparison between marking tools and cutting tools
- Purpose: Marking hand tools are used for measuring and marking out workpieces, while cutting hand tools are used for actually cutting and shaping wood.
- Examples: Some examples of marking hand tools include measuring tapes, rules, squares, bevel gauges, protractors, calipers, and scribes. Some examples of cutting hand tools include chisels, handsaws, planes, and spokeshaves.
- Precision: Marking hand tools are generally more precise than cutting hand tools, as they are used for measuring and marking out precise locations and dimensions on workpieces. Cutting hand tools are used for rough shaping and are not usually as precise.
- Power source: Marking hand tools are generally not powered by any external source, while cutting hand tools can be powered either by hand or by electricity.
- Maintenance: Marking hand tools generally require less maintenance than cutting hand tools, as they do not undergo the same level of wear and tear. Cutting hand tools, especially those powered by electricity, may require regular sharpening or replacement of blades.
Presentation
The topic is presented step by step
Step 1:
The class teacher revises the previous topics
Step 2.
He introduces the new topic
Step 3:
The class teacher allows the pupils to give their own examples and he corrects them when the needs arise
Conclusion
The class teacher wraps up or conclude the lesson by giving out short note to summarize the topic that he or she has just taught.
The class teacher also goes round to make sure that the notes are well copied or well written by the pupils.
He or she does the necessary corrections when and where the needs arise.
