Hand Tools
Name 5 basic hand tools
Spanners (Ring, Open ended/ ring, Double open ended)
Sockets and Drive accessories (Ratchet, Breaker bar, standard socket, 6 point socket, 12 point socket)
Screwdrivers (Flat tip, Phillips Head)
Files (Flat, round, half round, three sided)
Hammer (Ball Pien, Straight Pien, cross Pien, mallet)
What is important to do when selection and using power tools and equipment
Ensure the tools and equipment is serviceable and clean
Safety devices if fitted are in place
Any statutory inspections are completed
Know how to turn the equipment off in an emergency
What are the advantages of Pneumatic Power Tools?
Pneumatic power tools are usually more compact than electric tools
Speed can be varied by adjustment of supply air pressure
Higher rotational speeds are useful for small grinders and polishing stones
Safety is improved, especially where moisture is present and in a flammable environment
Pneumatic power is especially useful for riveting.
Name 5 precision tools
Micrometer, Vernier caliper, depth gauge, go/no go gauge, Verier height gauge
Name three classes of lubricants used in aviation
Aero oils, grease, inhibitors
When cutting threads what is a tap used for
To cut an internal thread
Some features of the bench drill are:
They are usually belt driven
They have a drill shank capacity of 13 mm or less
For general purposes, their spindle speeds range from a few hundred revs per minute to a few thousand revs per minute
Hand (manual) feed of the drill bit is generally employed. For drilling small holes, this hand feed is made sensitive by balancing the weight of the spindle with a return spring
The work piece can be held in a machine vice, which in turn can be attached to the machine table
What PPE is required/ recommended for employees working with pneumatic tools.
Eye protection is required and face protection is recommended
What in an advantage of an electronic caliper
conversion to either Imperial or Metric measurements
What is the function of a Lubricalt
Reduces friction
Provides cooling
Seals and cushions
Protects against corrosion
Cleanses.
'What are torque wrenches used for
A torque wrench is a precision measuring tool that measures the amount of torque required to turn a fastener.
What are three types of hand or portable grinders?
Angle grinders
Straight grinders
Die grinders (sometimes known as 8pencil9 grinders).
What is the main source of power for pneumatic tooling?
Shop compressed air
The Vernier calliper consists of?
A fixed jaw which is an integral part of the beam upon which is engraved the main scale
A sliding jaw which is an integral part of the sliding head which carries the Vernier scale and a
Øxing screw
A clamp member incorporating a Øne adjustment and a fixing screw (some models only, others have a press button friction brake)
Nibs for taking internal measurements (sometimes the outside edge of the jaws)
A probe for depth measurement (some models only)
Target points which are two small holes and are used for the accurate setting of dividers. (some models only)
True or False?
Type I and II must not be mixed
True
What are some means of removing a broken bolt, stud or tap
Taper screw extractor, straight screw extractor, metal disintegrator
Electric nibblers and jigsaws are used for?
metal cutting
What can be installed in the plumbing to ensure that air passing through tools is dry and will permit adjustment of the air pressure when required?
Airline filters/regulators
Micrometers are available to take accurate Imperial or Metric measurements and to read to?
0.0001" or 0.002 mm by the addition of a Vernier scale on the barrel.
What are three common types of grease used in aviation
AeroShell grease 7
AeroShell grease 17
AeroShell grease5
What colour handle sheet metal sheers cut left hand curves
Red Handle
Some features of the upright drill press are?
It is checked for plumb (perfectly vertical) and then bolted to the floor.
It is belt or gear driven.
It may have a drill shank capacity of 65 mm. Special machines may have capacities much larger than this.
It has a very wide range of spindle speeds available. Dial or lever selection of the spindle speed is often available.
Complex work tables that may swivel and tilt may be provided. In large machines the work table may be operated by a separate elevating motor
What is used to remove material from large and cumbersome items accessible only with portable equipment.
High Speed Pneumatic Grinder
What is a disadvantage of electronic vernier and can it still be used
flat battery and yes it can from the verier scale
