Tool Identification

Ag StructuresSlide2

Terms

Tools-any instrument used in doing work

Hand tool

- any tool operated by hand to do work

Power tool

- operated by some source of power other than human powerSlide3

Advantages of Using Hand Tools

Effective & efficient

Use hand tools when electrical or engine power is not available

Used for small jobs, where large machines can’t functionSlide4

Selecting Hand Tools

Select quality toolsBrand names=better quality tools

Using wrong tool can be dangerous, can damage the tool, and result in inferior workSlide5

Layout Tools

Tool used to measure or mark wood, metal, and other materials.Slide6

Tape Measurer

Come in lengths ranging from 6 foot to 30 foot, a width of ½ to 1 inch,

Can lock open, and use a spring to retract the tape with the push of a button.Slide7

Combination Square

Determining 45 and 90 degree anglesSlide8

Framing Square

Squaring cut corners and laying out stairs and raftersSlide9

Try Square

Other Measuring Layout Tools

Electronic Tape Measure

Divider-

Marking

Gauge

Chalk

LineSlide13

Once materials are measured and marked, they need to be cut, shaped, and bored as needed to prepare for assemblingSlide14

Saws

Classified by use and teeth per inch. An 8-point saw would have 8 teeth per inch.

Handsaws include the:

Crosscut, rip, compass or keyhole, coping and backsaw

.Slide15

Coping Saw

Cutting curves and irregular cuts in thin materialsSlide16

Hack Saw

Used for sawing

metalSlide17

Shaping Tools

Includes planes, wood chisel, and rasps.Slide18

Plane

Tool used to smooth surfaces and change the size or shape of wood materials.Planes include:

Jack Plane

Smoothing Plane

Block PlaneSlide19

Jack Plane

Usually 14 inches longUsed for smoothing long surfaces by shaving with the grain of the woodSlide20

Smoothing Plane

Usually 8 inches long,

Used with the grain and to finish smoothingSlide21

Block Plane

Usually 6 to 6½ inches long Used for smoothing the ends of boards by cutting across the grain.

To avoid splitting corners, clamp a piece of wood on both edges of the board or plane from the edge toward the center.Slide22

Wood Chisel

Wedge-shaped cutting tool used to cut notches and shaving off excess woodCome in a variety of widths and are generally hit with a wooden mallet. Slide23

Wood Chisel

Keep the chisel sharp for safe and effective use. To mark a slot turn the bevel of the chisel inward and up to cut shallow, and down to cut deep.Slide24

Wood Rasp

Also known as a wood file

Used for smoothing rough work and for removing small amounts of wood on curved and irregular-shaped objects. Slide25

Wood Rasp

Be sure the rasp has a handle.

Apply pressure on the forward stroke.

Clean the rasp with a wire brush or file card.Slide26

Boring Tools

Includes thehand drill

push drill

brace and bitSlide27

Hand Drill

Device with gears that drive its bit much faster than the handle turns

It is used for small holes when it is not convenient to use an electric drillSlide28

Brace

Device for holding and turning an auger bitSlide29

Auger Bit

Square tang to fit into the brace.

The cutting end has a feed screw, cutting lips,

and cutting

spurs Slide30

Auger Bit

Drill until the feed screw begins to come through the wood, then back out the bit, and turn the wood over to finish the hole from the other side

Prevents the wood from splintering outSlide31

Holding or Gripping Tools

Help

complete the job quicker, easier, and safer

Clamps and

vises

Used

to hold or grip wood or metal while being cut, shaped, bored, and fastened

Pliers

, wrenches

, and screwdrivers

Used

at times for holding, gripping, or turning.Slide32

C-Clamps

Clamping two or more pieces of metal together

Named after

It’s C ShapeSlide33

Bar Clamps

Adjustable clamp that can range from a few inches to six feetSlide34

Hand Screw Clamp

Clamping wood

together

Can span up to 10 inches

Requires two hands for tighteningSlide35

Miter Clamps

Used for tightening corners Example: Making a picture frame.Slide36

Combination Pliers

Also called adjustable & slip joint

Adjust

for holding various size

materialSlide39

Needle Nose Pliers

Reaching into recessed

areas

Twist wireSlide40

Diagonal Cutting Pliers

Also known as Lineman’s Pliers

Surface

and diagonal wire cuttingSlide41

Groove Joint Pliers

Several size adjustments

Gripping

when great pressure is neededSlide42

Vise Grip Pliers

For extra firm grippingSlide43

Wrenches

Used for gripping and tightening Include

adjustable jaw,

Turning hex head nuts and bolts.Slide48

Socket Sets

Offer the option of a breaker bar to loosen tight nuts.

Offer speed of a ratchet handle to loosen the nuts quicklySlide49

Allen Wrench

Turning

Hex head sockets screwsSlide50

Screwdrivers

Either:Standard

PhillipsSlide51

Standard or Flat Blade

Used with standard size slotsSelect a screwdriver that fills the width and depth of the screw slot

Longer handles give the maximum leverage for tightening and looseningSlide52

Phillips Screwdriver

Turning

Phillips

head

screws

Easier to tighten or loosed because of screwdriver is less likely to slip out of the screw slot.Slide53

Driving

Driving tools

To fasten building materials together.

Examples:

Hammers and StaplersSlide54

Curved Claw hammers

Most commonly used hammers to drive and pull nails.

Handles may be wood, metal, or fiberglass. Slide55

Using a Curved Claw Hammer

Whatever the nail size:Hold the nailTap it until it will stand on its ownThen grip the handle near the end hitting the nail square with a long swinging stroke. Slide56

Straight Claw hammers

Can be used to rip boards.Just as good as the curved claw hammer for driving nails

Not as effective when trying to pull bent nailsSlide57
