INFORMATION SHEET 1.1-1
Common Layout tools
Learning Objectives: After reading this information sheet 1.1-1, you should be able to:
1. Distinguish between measuring, marking, and
2. Layout tools.
3. Lay out lines and geometric shapes.
4. Transfer shapes to working material.
5. Maintain measurement and layout tools
Introduction:
Accurate measurement and layout is essential for high quality cabinetmaking. You must be able to transfer the shapes of your design onto your materials. With skillful measuring, you can mark, cut, and assemble parts with precision. Much of cabinetmaking relies on square edges and joints. Squareness simply means that all corners
join at a 90° angle.
Why Use Hand Tools?
"Man without Tools is nothing; with tools he is all." - This sentence is defined by Thomas Carlyle has well elaborated the importance of tooling to a man.
The term 'Tooling' as applied to the engineering discipline refers to any equipment or instruments that give helps in the production of a product or any related activities. Simply speaking, it ranges from the most fundamental type of hand tools such as a File to the very complex machine tools such as a CNC Machining Centre.
Thus, one may ask the question - Why we still have to use band tools in this modern age of technologies?
Yes, it is reasonable to say that the efficiency of any hand processes is low and the outcome quality depends highly upon the skill of individuals. Perhaps it is fair to consider the following points before a definite answer is given to the above question:
1. Accuracy
Although the CNC machine can give a higher degree of dimensional accuracy when compared with the inconsistent outcome of hand fitting, the extreme high degree of flatness required for a surface table or a machine slide way is usually obtained by hand scraping only.
2. Flexibility
Hand processes are very flexible and can be carried out at any place where necessary while machining processes are not. In addition, machining usually require a rigid setting up, while fitting is simple.
3. Quantity
For large batch size, advanced production machines are commonly employed in order to maintain the accuracy as well as the efficiency. But for "jobbing type" works, such as the manufacture of a prototype or the repairing of a single component, it would be uneconomic to use these advanced machine tools. Instead, "jobbing type" works are usually produced by conventional machining and followed by hand fitting where necessary.
4. Final Assembly
In the assembly of precise component parts, no matter how accurate they are being produced, a skilled fitter is often required to give the necessary "finishing touch" on them to ensure that everything goes together correctly.
HAND TOOLS
Scriber is a sharp, pointed tool used to draw straight sharp lines. | 
A scriber is used with a square rule or straight-edge for drawing straight lines. This is particularly important when laying out. | The pocket scriber can be reversed in the handle for safety. Available with carbide or hardened steel point. |
• Divider
Dividers transfer distances directly from the rule to the work and are used to scribe equally spaced divisions. They are also used to scribe arcs and circles. | 
Dividers are available in various sizes. | Dividers are usually set to rules. Similar to a pencil compass, it consists of two sharp points. Points may be lightly honed for sharpness. |
• Center punch
Center punch is used to enlarge prick punch holes. | 
Center punch has an included point angle of 90 degrees. | Center punches are used to mark the workpiece prior to machining operations such as drilling and should not be used in place of a layout punch. |
• Hammer
The type most commonly used is the ball pein hammer, which has a flat striking face and a ball-shaped end (call the pein). Hammer heads are made from medium carbon steel. The two ends must be hardened and tempered, the centre of the head with the eye being left soft. It is specified according to its weight.
• Combination square
The combination square is used for a number of layout operations. The set consists of a blade(graduated rule), square head, protractor, and center head.
• Height gauge
The height gauge is a caliper with a special foot block to adapt it for use on a surface plate. Height gauges are available in several sizes: the most common are the 10, 18, and 24 inch gauges in English measure and the 25 and 46 cm gauges in metric measure. Like the vernier caliper, these height gauges are graduated in divisions of 0.025 inch and a vernier scale of 25 units for reading measurements to thousandths of an inch. Always be sure the bottom of the foot block is clean and free from burrs.
• Steel rule
A steel rule is one of the most common hand tools used. Steel rules are often used to make
rough measurements and are not extremely precise.
• Angle plate
Angle plate is used in layout work and in setting up the work piece for drilling or milling at a 90 degree to the table. | 
Angle plates are a common layout accessory. | 
Angle plate / layout |
• Square block
• Trammel
Trammel measures between two points and scribes circles or arcs that are too large for dividers. | 
Trammel | Trammel points can be attached to a bar and set to circle dimensions or they may be clamped directly by rule graduations. |
• Bevel protractor
The bevel protractor consists of an adjustable blade with a graduated dial. The blade is usually 12 inches long and 1/16 inch thick. The dial is graduated in degrees through a complete circle of 360°. The most common use for this tool is laying out precision angles. The vernier scale is used for accurate angle adjustments and is accurate to 5minutes or 1/12°.
• Hermaphrodite
Hermaphrodite caliper locates and scribes lines in a work piece parallel to its side. | 
The hermaphrodite caliper can also be used to lay out the center of round stock. | Available in many sizes. Reversible for inside lines. It consists of two legs, one sharp point and the other leg is a hook. |
• Prick punch
Prick punch is used lightly mark the location of holes. | 
The prick punch has an included point angle of 30 degree. | The prick punch is the only punch that should be used in layout. It is used to preserve the location of a layout mark while doing minimum damage to the work piece. |
• Vee-block with clamp
V-blocks hold round stock for layout work. | 
Round work pieces can be securely fastened in a set of V-blocks. | 
To prevent the shaft from bending under cutting pressure a V-block and screw jack can be used to support the shaft. |
Files
Files are the most important hand tools used for the removal of materials. They are made of hardened high carbon steel with a soft 'tang'. to which a handle can be fixed. Files are categorised as follows:-
File
Length - measured from the shoulder to the tip.
Shape - the cross-sectional profile.
Grade - the spacing and pitch of the teeth.
Cut - the patterns of cutting edge.
Save Edge
There are no cutting edges on one side of the hand file. The purposes for the save edge is to avoid the worker damage the work, when he is filing a shoulder position. Shape of Files
1. Hand File - The common file used for roughing and finishing. It is a rectangular in section and parallel in width. It has double cut teeth on two faces, single cut teeth on one edge, and one save edge. | 
Figure 22a. Hand File
|
2. Flat File - It is similar to a hand file rectangular in section, tapered slightly in width and thickness towards the tip. It has Double Cut teeth on two faces and Single Cut teeth on two sides. | 
Figure 22b. Flat File
|
3. Half-round File - The section is a chord of a circle with its taper towards the tip. It is used for forming radii, grooves, etc. and the flat side is used for finishing flat surfaces. | 
Figure 22c. Half-round File
|
4. Round File - This is of round section tapering toward the end. It is used for enlarging holes, producing internal round corners. Usually double cut in the larger sizes, and single cut for the smaller sizes. | 
Figure 22d. Round File
|
5. Square File - This is square in section, with tapered towards the tip, and usually double cut on all four faces. It is used for filing rectangular slots or grooves. | 
Figure 22e. Square File
|
6. Three Square File - It is also known as triangular file. This is a triangular in section, with tapered towards the tip with double cut on both faces. It is used for filing corners or angles less than 90° | 
Figure 22f. Three Square File
|
Vernier Calipers are more precise tools capable for measuring external dimensions, internal dimensions, and depths. Besides the two pairs of measuring jaws and the depth gauge, its main features also include a main scale and a vernier scale. | 
Vernier Calipers |
The resolution of a vernier scale is determined by the difference on the distance of one division on the main scale and one division on the vernier as shown in figure 4. For example: A vernier scale of length 49mm is divided into 50 equal divisions. That means ONE division on the vernier represents 49/50=0.98 mm while ONE division on the main scale represents 1mm. Then, the resolution of the vernier is 1mm - 0.98mm = 0.02mm. |  . Vernier Reading

A drill is a tool fitted with a cutting tool attachment or driving tool attachment, usually a drill bit or driver bit, used for boring holes in various materials or fastening various materials together with the use of fasteners. The attachment is gripped by a chuck at one end of the drill and rotated while pressed against the target material. The tip, and sometimes edges, of the cutting tool does the work of cutting into the target material. This may be slicing off thin shavings (twist drills or auger bits), grinding off small particles (oil drilling), crushing and removing pieces of the work piece (SDS masonry drill), countersinking, counter-boring, or other operations.
Drills are commonly used in woodworking, metalworking, construction and do-it-yourself projects. Specially designed drills are also used in medicine, space missions and other applications. Drills are available with a wide variety of performance characteristics, such as power and capacity.
A tri- square is a woodworking or a metal working tool used for marking and measuring a piece of wood. The square refers to the tool's primary use of measuring the accuracy of a right angle (90 degrees); to try a surface is to check its straightness or correspondence to an adjoining surface. A piece of wood that is rectangular, flat, and has all edges (faces, sides, and ends) 90 degrees is called four square. A board is often milled four square in preparation for using it in building furniture.
A traditional try square has a broad blade made of steel that is riveted to a wooden handle or "stock". The inside of the wooden stock usually has a brass strip fixed to it to reduce wear. Some blades also have graduations for measurement. Modern try squares may be all-metal, with stocks that are either die-cast or extruded.
"Try square" is so called because it is used to "try" the squareness.
A jigsaw power tool is a jigsaw made up of an electric motor and a reciprocating saw blade. A jigsaw with a bevel function on the sole plate allows cutting angles of typically up to 45 degrees relative to the normal vertical stroke for cutting miter joints.In the past, what are now usually called scroll saws were often referred to as jigsaws.A power jigsaw may also be referred to, by some manufacturers, as a "bayonet saw" or Sabre saw.
Drillin is the process of cutting holes in metals by using a drilling machine .Drills are the tools used to cut away fine shavings of material as the drill advances in a rotational motion through the material.
Lamons Kammprofile gaskets are recognized as a problem solver for heat exchangers, large vessels, and equipment that experience excessive movement due to thermal expansion. The Kammpro provides one of the tightest seals combined with superior load bearing characteristics. Kammpro gaskets consist of a sealing core metal with or without guide ring. The sealing core is a solid metal gasket with concentric serrations on both sealing surfaces and faced with soft material such as flexible graphite, EPTFE, or the HTG configuration depending on operating conditions. It is the preferred design when needing improved performance at low seating stresses. The simultaneous actions of a high compressibility facing material on the outside of the grooved metal in combination with limited penetration of the tips of the solid metal core enhance the interaction of the two materials. This allows the component to perform individually to their optimum capabilities.
It is available in different materials and shapes such as non-circular shapes which produced efficiently with extreme accuracy to fit various bonnet connection shapes, also it can be custom engineered to fit various applications. The suggested flange surface finish for Kammpro gaskets is 125-250 RMS.

INFORMATION SHEET 1.1-2
Procedures in laying out work piece
Learning Objectives:
After reading this information sheet, you will be able to describe the purpose of layout and benchwork operations. List common benchwork operations. Describe the advantages of layout. Match the type of layout tools with their descriptions. Describe the layout procedure for the sample part.
Introduction:
Layout operations help ensure that you meet the proper tolerances required by the blueprint. Metal cutting operations on the manual mill, often require a great deal of precision. Manual machines are used to produce smaller batches of parts with a significant amount of detail. For this reason, these parts may require a number of benchwork operations. Benchwork operations include any operation performed before or after the cutting of the part. These operations help ensure the proper level of accuracy specified on the blueprint.
One of the most common bench work operations performed before cutting a part is layout. Layout is the process of marking lines, circles, or centers on metal work pieces. These marks represent the required features shown on the blueprint, including dimensions, hole locations, or other detailed areas to be machined. The purpose of layout is to place reference marks on the part, which can help eliminate mistakes that can occur during cutting. Laying out dimensions on a part can save time and reduce costs. This class will teach you about common bench work operations performed on the manual mill before and after machining a part. You will also learn about the tools required for these operations and how to perform common bench work procedures.
Basics
A firm surface, not necessarily a bench and a good light are essential.
Make sure that the sheet of metal is clean so that any mark made will be visible and unambiguous. Clean the surface with a glass brush or fine sandpaper.
Glass brush is great for cleaning work but can be an irritant if pieces get into your skin. Try to work away from the bench on some old newspaper that can be discarded whenever possible I use a glass brush under running water. Just try to ensure that you don’t get a build-up of glass brush on the bench and DON’T blow the bits around.
If you have a problem seeing the scribe marks then cover the surface with ‘engineers blue’ if you want to be posh or thick felt tip pen if you’re common like me.
Method
1. The first and most important thing is to establish a datum point and datum lines on the metal. The long edge of the metal should be checked for straightness with the ruler by holding one against the other and holding them up to the light. Correct any faults with a file. File a second edge at right angles to the first. Check with the set square.
2. This right angled corner is your zero point or datum and the two edges are your datum lines.
3. All measurements will be taken from these datum. (Alternatively, you can scribe a line, say 5mm, parallel to each edge, and use these as your datum. The point that the two lines cross will be the zero datum point.)
4. Take a minute to plan the sequence in which you will work. For example start with the main outline, including any radii that the profile might have, then any cut outs, such as horn blocks, and then the centres of any drill holes.
5. Remember that the centre points of some radii may lie outside of the profile so, if you have enough metal, leave room on the metal for these centres. If the finished piece has one long straight edge, like a main frame, plan to leave one of the datum edges as that edge.
6. Make the initial marks very lightly, so that if you have to correct them there will be less confusion.
7. To mark a straight line, place the work on a firm surface and carefully mark the position of the line relative to the datum line. This can either be done directly from the ruler or transferred from the ruler to the work using the dividers. Make a small mark approximately at each end of the line to be drawn.
8. Place the tip of the scriber on one of the marks, preferably the one furthest from you and, with the ruler held down with the fingers of your left hand, slide the ruler up to touch the scriber.
9. The best working position is to have the ruler pointing away from your chest. That way you will be able to see and reach the edge which is touching the metal. Turn the work around to find a comfortable position.
10. Looking from the top, note the relative positions of the ruler and the mark, (the thickness of the scriber will hold the ruler slightly away from the mark) and holding the scriber and the top of the ruler in place, slide the lower part of the ruler up to the second mark so that it is the same distance away from the mark as the top part of the ruler.
11. Making sure that the ruler is now held firmly down to the metal, draw the scriber down towards you with enough pressure to leave a fine line. The line can be a little longer than necessary.
12. This is not as easy as using a pencil and paper and you can slip, so exercise caution and practice until you feel confident.
13. Using a set square will also need some practice. The thick arm is held against the datum edge and you scribe up against the thin arm. You cannot do this flat on the bench because of the thick edge, so rest the work on a book or something to raise the thick edge clear, but make sure that the thick edge is up against the work and not the book. It is usual to hold the set square with the thumb and the work with the fingers of the left hand.
14. When using dividers the need for caution is just as great. You must calculate and mark the centres of any arcs in the profile or holes to be drilled. Apply some pressure to the point of one leg of the dividers, at the centre point of the circle, so that the point digs into the metal and anchors itself, remembering that with thin metal you will mark right through if you go at it like a mad bull!
15. Most dividers have a small handle on the top. Having set the dividers to the radius of the arc, grip the handle between thumb and index finger and place one point back in the centre mark. Holding the work down firmly, gently scribe the arc or circle, using the thumb and index finger. Use as little wrist movement as is comfortable. As with the straight lines mark a little longer than the actual length needed.
16. The marks that you make should be good enough to be legible but not so hard that fine sandpaper will not remove them.
17. Once the work is complete, check your measurements again to be quite sure that everything is correct before you start cutting.
.
18. If you want to mark a line at right angles to another and cannot for any reason use the set square, first mark the point at which the two lines will cross. With the dividers on this mark, make marks on the line about one inch to either side. Open the dividers about another inch and make two marks above the first mark. A line drawn from where the two divider marks cross and the first point will be at right angles to the first line.
19. If you are marking out a piece of metal that is going to be bent at right angles then allow half the thickness of the metal extra for the bend. If, however, you intend to mitre the corner, for a cleaner corner, then this rule does not apply and less allowance for the thickness should be made. In this case make a test piece. Make a mark, say one inch exactly from the end of a piece of metal, file the mitre exactly on that mark, put in the bend and measure how much longer than inch it turned out.

Steps/ Procedure: 1. Prepare all materials needed for this task. The first and most important thing is to establish a datum point and datum lines on the metal. 2. This right angled corner is your zero point or datum and the two edges are your datum lines.
3. All measurements will be taken from these datum. (Alternatively, you can scribe a line, say 5mm, parallel to each edge, and use these as your datum. 4. Take a minute to plan the sequence in which you will work. For example start with the main outline, including any radii that the profile might have, then any cut outs, such as horn blocks, and then the centres of any drill holes. 5. Remember that the centre points of some radii may lie outside of the profile so, if you have enough metal, leave room on the metal for these centres. If the finished piece has one long straight edge, like a main frame, plan to leave one of the datum edges as that edge. 6. Make the initial marks very lightly, so that if you have to correct them there will be less confusion.

13. Using a set square will also need some practice. The thick arm is held against the datum edge and you scribe up against the thin arm. You cannot do this flat on the bench because of the thick edge, so rest the work on a book or something to raise the thick edge clear, but make sure that the thick edge is up against the work and not the book. It is usual to hold the set square with the thumb and the work with the fingers of the left hand.
14. When using dividers the need for caution is just as great. You must calculate and mark the centres of any arcs in the profile or holes to be drilled. Apply some pressure to the point of one leg of the dividers, at the centre point of the circle, so that the point digs into the metal and anchors itself, remembering that with thin metal you will mark right through if you go at it like a mad bull!
15. Most dividers have a small handle on the top. Having set the dividers to the radius of the arc, grip the handle between thumb and index finger and place one point back in the centre mark. Holding the work down firmly, gently scribe the arc or circle, using the thumb and index finger. Use as little wrist movement as is comfortable. As with the straight lines mark a little longer than the actual length needed. 16. The marks that you make should be good enough to be legible but not so hard that fine sandpaper will not remove them.
17. Once the work is complete, check your measurements again to be quite sure that everything is correct before you start cutting.
18. If you want to mark a line at right angles to another and cannot for any reason use the set square, first mark the point at which the two lines will cross. With the dividers on this mark, make marks on the line about one inch to either side. Open the dividers about another inch and make two marks above the first mark. A line drawn from where the two divider marks cross and the first point will be at right angles to the first line.
19. If you are marking out a piece of metal that is going to be bent at right angles then allow half the thickness of the metal extra for the bend. If, however, you intend to mitre the corner, for a cleaner corner, then this rule does not apply and less allowance for the thickness should be made. In this case make a test piece. Make a mark, say one inch exactly from the end of a piece of metal, file the mitre exactly on that mark, put in the bend and measure how much longer than inch it turned out.

Assessment Method: Return demonstration using performance criteria checklist. |
PERFORMANCE CRITERIA CHECKLIST 1.1-1
Performance Criteria Did you… |
|
Yes | No |
1. Prepare all materials needed for this task. The first and most important thing is to establish a datum point and datum lines on the metal. | / |
|
2. This right angled corner is your zero point or datum and the two edges are your datum lines. | / |
|
3.All measurements will be taken from these datum. (Alternatively, you can scribe a line, say 5mm, parallel to each edge, and use these as your datum. | / |
|
4. Take a minute to plan the sequence in which you will work. For example start with the main outline, including any radii that the profile might have, then any cut outs, such as horn blocks, and then the centres of any drill holes. | / |
|
5. Remember that the centre points of some radii may lie outside of the profile so, if you have enough metal, leave room on the metal for these centres. If the finished piece has one long straight edge, like a main frame, plan to leave one of the datum edges as that edge. | / |
|
6. Make the initial marks very lightly, so that if you have to correct them there will be less confusion. | / |
|
7. To mark a straight line, place the work on a firm surface and carefully mark the position of the line relative to the datum line. This can either be done directly from the ruler or transferred from the ruler to the work using the dividers. Make a small mark approximately at each end of the line to be drawn. | / |
|
8. Place the tip of the scriber on one of the marks, preferably the one furthest from you and, with the ruler held down with the fingers of your left hand, slide the ruler up to touch the scriber. | / |
|
9. The best working position is to have the ruler pointing away from your chest. That way you will be able to see and reach the edge which is touching the metal. Turn the work around to find a comfortable position. | / |
|
10. Looking from the top, note the relative positions of the ruler and the mark, (the thickness of the scriber will hold the ruler slightly away from the mark) and holding the scriber and the top of the ruler in place, slide the lower part of the ruler up to the second mark so that it is the same distance away from the mark as the top part of the ruler. | / |
|
11. Making sure that the ruler is now held firmly down to the metal, draw the scriber down towards you with enough pressure to leave a fine line. The line can be a little longer than necessary. | / |
|
12. This is not as easy as using a pencil and paper and you can slip, so exercise caution and practice until you feel confident. | / |
|
13. Using a set square will also need some practice. The thick arm is held against the datum edge and you scribe up against the thin arm.
