- It involves using hand tools like hammers, hacksaws, wrenches, and files.
Carpentry Benchwork
- Carpentry benchwork focuses on crafting furniture and frames for upholstered pieces.
- Each component is meticulously crafted by hand.
Hand Tools
- Hand tools are devices used to perform work on materials or physical systems using only hands.
- They can be manually used, or powered by electricity.
General Safety in Benchwork
- Recognize and follow safe work practices.
- Develop safe work habits.
- Be responsible for your own safety and the safety of others.
- Maintain safe work habits.
- Keep hands away from moving parts; receive immediate first aid following injuries.
- Maintain a clean, neat, and safe work area.
- Never wear loose clothing such as short sleeves or rolled-up sleeves, necklaces, rings or bracelets and tie up long hair.
Housekeeping
- Keep machines and hand tools clean.
- Keep work surfaces clean and free of oil or grease.
- Regularly sweep up metal chips from work surfaces.
- Never put tools or materials on the floor next to a machine.
- Do not place tools or materials on a machine table.
- Never use rags near moving parts; remove burrs from workpieces before handling.
Care of Hand Tools
- Store tools appropriately in a tool box.
- Use the right tool for the right job.
Laying Out
- This is a shop term used to mark materials.
- The process involves marking lines, arcs, and circles on a piece of metal to show the dimensions.
- This ensures accuracy in machined parts.
Layout Tools and Accessories
- Protractor: Measures angles ranging from 0 to 180 degrees with an accuracy of around 1°.
- Surface Gauge or Vernier Height Gauge: Used to mark parallel lines, often alongside a surface plate and angle plate.
Additional Tools and Accessories
- Steel Rule: A common linear measuring tool available in metric (millimeter, half-millimeter) or inch systems.
- Scriber: A layout tool used to draw lines on a workpiece.
- Center Punch: A tool to create a mark for drilling holes.
- Solid Square or Try-Square: Marking tools for angles and flat surfaces.
- Divider: A tool used to copy lengths or circles to a workpiece.
- Angle Plate: Used to ensure 90-degree angles to support workpieces.
- V-Blocks or Prism: A tool used for holding cylindrical workpieces for layout.
Laying Out with Try-Square and Steel Rule
- Remove burrs from the workpiece.
- Start laying out from a square machined surface.
- Use a try-square and steel rule.
- Position the scriber on the workpiece against the try-square edge.
- Draw the line to be laid out.
Hammers
- Hammers are weighted heads with handles used in metalworking.
- Types include hard, soft, and soft-face hammers; straight, ball peen, cross peen, and claw.
- Sledges are used for heavy work and vary in weight.
Bench Vises/Vises
- Machinist's Vises are heavy-duty tools with parallel jaws and either a fixed or swivel base.
- Utility Vises are used for general work with a small anvil and anvil horn.
- Vises need to be maintained correctly for their use.
- Be careful not to injure fingers, maintaining the tool, safety while working with them.
Clamps
- Clamps can be used to hold materials or fasten objects temporarily.
- They can be used when the vise is unavailable.
Screw Drivers
- Screw drivers are hand tools for turning screws.
- Types include standard and offset, and specialized types such as Phillips.
Pliers
- Pliers are hand tools for seizing, bending, or cutting wire and other thin materials.
- Types include side-cutting, long-nose, and diagonal-cutting pliers.
Wrenches
- Wrenches are hand tools for tightening or loosening nuts and bolts.
- Types include open-end, box-end, combination, socket, adjustable, monkey wrenches.
Files
- Files are steel tools for smoothing, polishing, or cutting metal.
- Types of files include: single cut, double cut, and bastard, second-cut, smooth and dead smooth.
- Classification of files is based upon teeth spacing or coarseness.
- Using a file involves applying the correct cutting pressure and rate of motion.
Chisels
- Chisels are used for cutting metals, removing metal from a surface, shearing off rivets, smooтhing castings, or splitting rusty nuts from bolts .
- Chisels are made of octagonal tool steel.
- Methods of preparing cutting edges.
Drills and Drilling
- Twist drills are tools for making holes by slicing metal during rotation.
- Flutes allow cutting fluid and chip removal, and different materials require suited drill types.
- Types of drills include high-speed drills and cemented carbide drills.
- Safe working practices and materials for different drilling conditions must be known.
Drill Press
- Drill presses are machines for drilling holes.
- Components include the base, column, table, drilling head, hand feed lever, depth stop, and chuck.
- Proper maintenance is necessary for optimal functioning.
Countersinking
- Used to enlarge the top of a previously drilled hole to accommodate the head of the fastener.
Reaming
- Reaming is used to enlarge existing holes, producing a smooth, round hole when finished.
- Tools for reaming includes hand reamers and machine reamers .
Counterboring
- Counterboring enlarges a hole's top to a specific depth for fitting specific fasteners such as a bolt or other threaded objects.
Tapping
- Threading internal holes, using tools called taps.
- Hand taps and machine taps
- Types of taps and wrenches.
