Study Notes
Hand Tools and Bench Work
- Hand tools are tools held in the hand and operated without electricity or other power.
- Bench work refers to work done at a workbench, worktable, etc.
Work Holding Tools/Devices
-
Bench Vise - A swivel based bench vise is commonly used for general work. It is fastened to the bench with bolts and has serrated, hardened jaws for a firm grip on work.
-
V-Blocks - Used to hold circular work for laying out or setting up for machining. Some are fitted with clamps for a secure hold.
-
Toolmakers’ Handvise - A small steel vise with interchangeable blocks used for holding work during operations like drilling and tapping.
-
C-Clamp - A versatile clamp used to hold workpieces on drill presses and clamp parts together.
-
Toolmakers’ Parallel Clamp - Consists of two flat steel jaws which can be adjusted by means of a screw passing through the center of each jaw. Used for holding small parts at the bench and machines.
-
Vise Grip - A latching mechanism with a high degree of mechanical advantage, making it very strong when locked down.
Work Cutting Tools/Devices
-
Saw - Consists of a tough blade with a toothed edge used for cutting materials, often wood. The cut is made by placing the toothed edge against the material and moving it forcefully.
-
Hand Saw - Used for cutting pieces of wood into different shapes.
- Crosscut Saw - Cuts wood perpendicular (across) to the grain.
- Rip Saw - Cuts wood parallel to the grain.
-
Coping Saw - Used for cutting intricate external shapes and interior cut-outs in woodworking or carpentry.
-
Hacksaw - A hand tool with a fine-toothed blade tensioned in a C-frame, commonly used for cutting metals and plastics.
-
Tin Snip - Used for cutting thin sheets of metal, plastic, fiber, etc.
Work Striking Tools/Devices
-
Hammer - A tool that delivers a blow to an object, used for driving nails, forging metal, and breaking apart objects. There are various types including:
- Ball-peen Hammer - Used for general work (flat face) and peening and riveting (round end)
- Straight Peen Hammer - Used for stretching and drawing out metal when forging.
- Cross Peen Hammer - Used for stretching and drawing out metal when forging.
- Claw Hammer - Used for extracting nails.
-
Mallet - A smaller type of hammer often made of rubber or wood, with a relatively large head.
-
Chisel - A tool made of hexagon or octagon shaped tool steel. One end is shaped for cutting, the other end receives blows from a hammer. Chisel types include Flat Cold Chisel, Cape Chisel, Round Nose Chisel, and Diamond Point Chisel.
Work File Tools/Devices
-
File - A hand-cutting tool with many teeth used to remove burrs, sharp edges, and surplus metal, producing finished surfaces. They are made of high-carbon steel.
- Tang: The handle attachment point.
- Length: The overall length of the file.
- Tip: The pointed end.
- Edge: The cutting edge.
- Heel: The wide end.
- Face: The flat surface of the file.
-
Classes of Files
- Single-Cut Files: Have a single row of parallel teeth, used for smooth surfaces and harder metals.
- Double-Cut Files: Have two rows of teeth crossing each other, removing metal quickly and making for easy clearing of chips.
-
Degree of Coarseness - Files are produced in various degrees of coarseness, indicated by terms like rough, coarse, bastard, second-cut, smooth, dead smooth, or numbers from 00 to 8 (00 being the coarsest).
-
Shapes of Files - Files are identified by their cross-section, shape, and special use. Common types include Mill, Flat, Hand, Pillar, Square, Round, Three-Square (triangular), Half-Round, Crocket, Crossing, Waring, Barrette, and Knife.
-
Care of Files
- Always use a file with a handle.
- Do not knock a file on a vise or hard surface to clean it.
- Keep a firm grip on the file at all times.
- Never use a file as a pry or hammer.
- Store files separately to preserve their edges.
-
Filing Techniques - Different files and techniques are used depending on the task at hand.
Measuring Instruments
-
Measurement - The act or process of determining dimension, capacity, or amount.
-
Ruler (rule or line gauge) - An instrument used to measure distances or rule straight lines.
-
Types of Rulers:
- Steel Rule - Graduated in inches/fractions and centimeters/millimeters.
- Narrow Rule - Made of tempered steel used for measuring in small openings and spaces.
- Hook Rule - Has a hook for measuring from an inside edge.
- Flexible Steel Rule - Made of tempered spring steel, used for general use or measuring curved work.
- Short Length Rule Holder - Used for taking measurements in small openings, with interchangeable blades.
- Tape Rule - A metallic tape used for measuring bar stock and long materials.
- Rule Depth Gage - Designed to measure the depth of holes and slots.
-
Caliper (transferring tools) - Tools used to measure a work piece by contact rather than by scale reading.
- Caliper measurements are set by a steel rule and then used to check a work piece.
- The method can also be reversed, with the contact tool set by the work piece and then checked on a steel rule.
