CARPENTRY BASIC TOOLS


Basic Carpentry Tools



            Carpentry requires a number of power tools and hand tools to complete the job. A carpenter is usually the person who lays down woodwork at a construction site. From the wooden frame supporting the house to a finished wood floor, carpenters are responsible for the accuracy and integrity of the wooden parts of a building. A carpenter will use a number of tools to make sure that the woodwork is level and straight, securely fastened and beautifully finished.

Function
Carpentry tools are used to cut materials, to balance angles and level in a structure, to gauge and mark placement and to secure materials. Other carpentry tools are also used to finish or reshape surfaces and apply putty or adhesive.
Layout and Leveling
Any time you make a level surface, you need to check to make sure it's accurately leveled to ensure neatness and structural integrity in the building. Tools commonly used for layout and leveling include a protractor, level, framing square and plumb bob. 

PROTRACTOR
 A protractor is used for measuring angles.



 LEVEL


  

          A common type of level is the water level, which uses a bubble in a tube of water to make sure your surface is level.


FRAMING SQUARE

           A framing square is a 90-degree-angle ruler that makes sure your corners are square.


PLUMB BOB

          A plumb bob is a balanced weight that hangs on a string to make sure that a surface is straight up and down.



Cutting and Shaping      
Types of tools used by carpenters to cut and shape wood include chisels, saws, and sanders. 


CHISELS
            A chisel is a metal tool with a prying edge that's used to remove wood in order to shape it.


SAW
       A number of types of saws are used in carpentry, depending on the type of work that needs to be done.
 Types of saws used by carpenters include:
          1. Hacksaws

          2. Keyhole saws  


          3. Crosscut saws.




SANDER
      Since a carpenter works heavily with finishing wood, a professional carpenter will require a number of differently shaped sanders--both electric power sanders and delicate hand sanders--to complete the job.

Fastening
Carpenters must securely fasten building frames and other carpentry using fasteners like adhesive, screws and nails. 

NAILS
 
In engineering, woodworking and construction, a nail is a pin-shaped, sharp object of hard metal or alloy used as a fastener.

ADHESIVE
 By definition, anaerobic adhesives remain liquid until isolated from oxygen in the presence of metal ions, such as iron or copper.

SCREW
 A screw, or bolt, is a type of fastener characterized by a helical ridge, known as an external thread or just thread, wrapped around a cylinder.



NAIL HAMMER
           
 A carpenter will have a nail hammer to drive nails, and should also have a power drill equipped with bits and screwdriver heads appropriate for drilling holes and driving screws into the project materials.

CLAMP

            When fastening the materials, a carpenter will often use a clamp to temporarily hold the materials in place while a fastening material is applied. A clamp can hold things into place while drill holes are screwed or to hold the structure steady while a strong adhesive dries in place. Types of clamps used for this purpose include C-clamps, hand screws, spring clamps and web clamps. A carpenter may also use tape to help secure materials while they are being secured.
Safety
Tools used by carpenters to ensure safety and protection include eye protection such as goggles, a dust mask and ear plugs. The eye protection and dust mask offer protection from particulate matter, such as sawdust and building material debris which might enter the air. The ear plugs should be worn to protect your hearing from damage when you are performing a large task, such as using an electric saw.
