Augar Ɵ4”, 1 ” , ½” Nos 01 2 1- Tool Bag : This is a protective bag to keep carpenter tools in it. The Toolkit Bag shall be made of heavy-duty plain-woven canvas fabric weighting 240-300 gm/sq. yard. Bag should have back strap in order to carry on shoulders. It shall have adequate slots for placing tools. 2- Hand Saw: Hand Saw is used to cut across the grain of wood. Cutting blade usually 10 or 12 inches long, is made of carbon steel. These are normally ‘ Crosscut saw’ where each cutting tooth is angled to cut with one edge and push sawdust out with the other. Blade should contain 10 to 15 TPI (teeth per inch). The handle should be made of plastic/ wood for proper gripping & working. 3- Try Square 150mm: Try square are L-shaped, with a thin metal blade that is marked in graduations like a ruler and a “STOCK” called the body, which is thicker than the blade having thickness 1.8mm to 2.0mm. Try square is normally made of polished steel. Try square is used primarily to mark a straight/ right angle (90 0) line across a piece of wood for cutting. 3 4- Steel Measuring Tape 3m: A measuring tape is a flexible ruler. It consists of metal strip with linear-measurement markings . It is a common measuring tool . Its design allows for a measure of great length to be easily carried in pocket or toolkit and permits one to measure around curves or corners. This should be made of steel having better corrosion resistance and longer service life. The tang is connected to the tape with loose rivets through oval holes, and can move a distance equal to its thickness, to provide both inside and outside measurements that are accurate. 5- Firmer chisel 1”: It has a thick, strong blade that allows removal of large pieces of wood in a single strike. Theses chisels are made with square cutting edges which are differentially heat treated for improved strength. Handle are wooden and are strengthen at the top with metal, stopping to split at the time of hitting. Chisel should be conforming to IS 5663-1970. In fact, this chisel's blade is strong enough to form deep, large joints when the end is hit with a hammer. This type of chisel has a beveled edge, and used for general woodworking. 4 6- Cutting plier 8”: It is made of steel by forging with sharp cutting jaws. It is used for cutting Stainless Steel sheet/ Mild steel wire and wire mesh. 7- Triangular file 125mm thick: A file is used to cut fine amounts of material from a work piece or sharpen the tools. It is made of a steel bar with a case hardened surface and a series of sharp, parallel teeth. This files have a narrow, pointed tang at one end to which a handle can be fitted. The triangular file or three-square file was traditionally used by carpenters to sharpen saw teeth. 8- Adjustable wrench 10”: Adjustable wrenches have one fixed jaw point at the top of the wrench and one moveable jaw. This is used for turning nuts, lag screws, bolts and other objects. 9- Cold Chisel: Cold chisels is highly tempered piece of tool , which is used to cut a piece of metal and to remove waste material when a very smooth finish is not required or when the work cannot be done easily with other tools, such as a hacksaw, file, bench shears or power tools. 5 10- Hand gloves (cotton): Hand gloves are made of heavy duty cotton with cushion inside for proper protection of hands during working. 11- Smoothing plane: Planes are used to smooth and shape wood by means of a sharp steel blade (housed in a wood or metal casing) set at an angle to the surface to be planed. The depth of the cut can be varied by adjusting the distance the blade protrudes beneath the bottom surface of the plane. Planes are made in many sizes, and special planes are sometimes used to cut channels. Files of various shapes are also used to smooth and shape wood. 12- Screw driver: A screwdriver is a tool for turning (driving or removing) screws. A typical simple screwdriver has a handle and a shaft, and a tip that the user inserts into the screw head to turn it. The shaft is usually made of tough steel to resist bending or twisting. The tip may be hardened to resist wear, treated with a dark tip coating for improved visual contrast between tip and screw—or ridged or treated for additional 'grip'. The screwdrivers also have interchangeable tips that fit into a 6 socket on the end of the shaft and are held in mechanically or magnetically. Handle are normally plastic made. Screw driver set shall be as per IS-844 (PART-I). 13- Claw hammer: A claw hammer is a tool primarily used for pounding nails into, or extracting nails from, some other object. The rounded end of the claw, in combination with the handle, is used to gain leverage when extracting a nail. The Claw hammer shall be conforming to IS: 6546/1989 with up-to- date amendments. The handle of Claw hammer shall be as per IS: 4953/1973 with up-to- date amendments. 14- Rukkhan (Mortise Chisel ): The chisel is forced into the material to cut out timber for mortise joints. The driving force may be manually applied or applied using a mallet or hammer. This chisel is thick, rigid blade with straight cutting edge and deep, slightly tapered sides to make mortises and similar joints. The Handles of chisel are generally made from polypropylene which has great strength allowing the chisel to be struck hard. 7 15- Hacksaw frame with blade 12”: Hacksaw is a fine-toothed saw, used for cutting metal. They can also cut various other materials, such as plastic and wood. Hacksaw shall be as per IS-5169 and hacksaw blade shall be as per IS: 2594. Hacksaws are hand saws with a C-shaped frame that holds a blade under tension. This has a handle, usually a pistol grip, with pins for attaching a narrow disposable blade. The frames may also be adjustable to accommodate blades of different sizes. A screw or other mechanism is used to put the thin blade under tension. 16- Bevel square 6”: A bevel gauge is an adjustable gauge for setting and transferring angles. The handle is usually made of wood or plastic and is connected to a metal blade with a thumbscrew or wing nut. The blade pivots can be locked at any angle by loosening or tightening the thumbscrew. The bevel can be used to duplicate an existing angle, or set to a desired angle. 17- Oil / Water Stone : Oil / Water stone lubricated with oil or water is used for sharpening cutting tools. These are generally coarse grit silicon carbide stone. A softer grade stone is used with water as the lubricant (versus oil) to develop a fast cutting slurry. Preferred grit size is 40-80 Micron. 8 18- Sprit level 300mm PVC x 2” width: A spirit level, bubble level or simply a level is an instrument designed to indicate whether a surface is horizontal (level). Sprit level is equipment which hold a trapped air bubble in liquid filled in glass/plastic pipe, which is properly fixed in metal/ wooden/plastic frame having level surface. When the level is moves the entrapped bubble moves. When the bubble is in centre of pipe, it shows that surface is horizontal.

    THE SPIRIT LEVEL PDF, EPUB, EBOOK Seamus Heaney | 80 pages | 08 Oct 2001 | FABER & FABER | 9780571178223 | English | London, United Kingdom The Spirit Level PDF Book Average rating 4. More studies evidently need to be carried out. Unfortunately, axioms B and C are sketchy and D is just plain wron I read this book because John thought I would find it interesting. Drawing on cutting-edge research from behavioral science and economics, Mullainathan and Shafir show that scarcity creates a similar psychology for everyone struggling to manage with less than they need. They used many examples of what different psychologists, philosophers and economists have called 'status anxiety,' 'luxury fever,' and 'affluenza'. I mean, it's a theory with pretty robust models but if you want to check each thesis then you should look at their references. Some of the graphs look like a shotgun target, but they've helpfully drawn a line through the center so that you can draw the right conclusion. Renowned researchers Richard Wilkinson and Kate Pickett offer groundbreaking analysis showing that greater economic equality-not greater wealth-is the mark of the most successful societies, and offer new ways to achieve it. Bikeopeli The flip side of this is that I don't think it is saying much if anything beyond what Veblen had to say at the dawn of the century, rather it reaches similar conclusions from the perspective of looking at the long term health of national populations.

B (August 2011) Installation, Operation, and Care of MODEL 6614 MEAT SAW SAVE THESE INSTRUCTIONS GENERAL The 6614 Meat Saw is rugged, durable, and easy to clean. The saw is equipped with a water resistant 3 HP electric motor and direct gear drive transmission that provides a blade speed of 3500 feet per minute. The carriage (Fig. 1) has stainless steel ball bearings providing easy travel and dependability. The shaped front edge of the carriage is comfortable to the operator's body even when leaned on during movement. The carriage lock is standard. The upper pulley cover and baffle are stainless steel. Table, carriage, pulleys, guides, and wiper assemblies can be quickly removed without tools for ease of cleaning. Moving parts are enclosed but accessible. The blade is guarded above and below the cutting zone. The pusher plate is provided to eliminate the need of handling items close to the blade; it can ride on the right "flanged-end" of the carriage so you keep your hands away from the cutting edge of the blade. For electrical specifications above 250 volts, a transformer provides a 151 volt control circuit voltage. One long-life blade is furnished with each saw as standard equipment. This blade cannot be re-sharpened; replacement blades are available through your local Hobart Service Office.

  • Introduction to Carpentry Tools and Joints
    INTRODUCTION TO CARPENTRY TOOLS 1. Try Square 2. Steel Rule 3. Marking Guage 4. Coping Saw 5. Tenon Saw 6. Penon Saw 7. Ironjack Plane 8. Benchwise 1. Try Square This is used to mark lines at 90 degrees to a straight edge. It is used to mark out lines square to the face edge and face side. It may also be used to check if edges are straight. If the try square is placed on the edge of the material and held up to a light, any light shining through between the material and the try square blade indicates that the edge of the material is not straight. 2. Steel Rule A steel rule is a very accurate marking and measuring tool. The steel is thin and the markings on the rule are very fine. The measurements are in millimetres on one edge and inches on the other. The steel rule can also be used as a straight edge to check if materials or edges of materials are straight. The measurements on the steel rule go all the way to the end unlike the plastic ruler. This is because the rule may be used to measure inside pipes. It may also be used to measure diameters and circumferences of pipes and tubes accurately. The end of the rule with the measurements to the edge is called the zero end. By: Harish Gupta Page 1 3. Marking Guage The marking gauge is used on wood.It is used to mark straight lines parallel to a straight edge.The marking tool has an adjustable stock (the stock slides up and down the stem) and is set using a steel rule.

  • Reversible Level
    REVERSIBLE LEVEL constructed by COOKE, TROUGHTON & SIMMS, L t d . The Reversible Level S 113, constructed by the firm Co o k e , T roughton & Sim ms, L t d ., Buckingham Works, York, is constructed so that the telescope may be set level for each sight by the manipulation of a highly sensitive setting screw, this method being now recognised by acknowledged authorities as more accurate and rapid than attempting to set the axis truly vertical and relying on the accuracy of the relation between this and the line of collimation. All observations are made from one stance but the special feature of this level is that its adjustment can be readily checked by the user without anything more than tur­ ning the telescope through 180° about the axis of collimation, and taking observations in the two positions. Further, this instrument, even if out of adjustment, gives “true level” as the mean of these two readings. The characteristics of this level depend on the ability of a reversible spirit level to determine a mechanical axis (and the coincident axis of collimation) in a horizontal plane. The spirit level, which has both upper and lower surfaces visible, is attached to the side of the telescope, and is so constructed that, when in either position of the telescope (see figure 2, A and B) the bubble occupies a similar position in relation to index marks, the instrument is in adjustment, i.e., when the telescope is truly level the bubble is in the central position. For this to be possible the effective surface of the spirit level, which is most simply described as being barrel-shaped, should be circular at all cross-sections throughout its length, and symmetrical in longitudinal section about its axis.

  • Achieving Perfect Angles Is a Common Pursuit in Woodworking—Especially
    The Deal Square By Tim Snyder chieving perfect angles is a common pursuit in Awoodworking—especially E 90° angles. But there’s no such thing as the perfect layout tool to check for square. at’s because the square relationships that occur in woodworking B C D F are surprisingly variable. One moment you’re squaring a bandsaw’s blade to its table; the next, you’re squaring a line across a full sheet of plywood or testing the corners of a frame-and-panel assembly. Handling these layout, A assembly, and alignment tasks with accuracy and e ciency has spawned an amazing variety of tools. e selection featured here is far from complete, but there’s H I a good chance you’ll nd a tool or two that deserves to be added to your arsenal. Having a good selection of squares is only part of the square deal. It’s also important to store these tools correctly— so that they’re protected but easily accessible. Jim Downing designed and built the beautiful case shown here. Make the case. A Starrett 4" double square ($84.50) See p. 56 for Here’s a pocket-sized square that gets plenty directions on of use because of its accuracy and easy making your own adjustability.
