  • The Back Street Bowyer Introduction This Guide Is Aimed at Someone
    The Back Street Bowyer www.alanesq.com v2.61 – Sep 10 Introduction This guide is aimed at someone who fancies having a try at making themselves an English longbow but who has no idea how to go about it (even if you have no woodworking experience at all) i.e. In exactly the same position I was in myself not so long ago I should point out that I have no training in the subject and most of what I am passing on here is either what people on forums have kindly passed on to me or I have figured out myself through trial and error. I strongly suspect much of what I say here will cause a real bowyer to laugh out loud, but what I can say is that using these methods I have made several bows ranging from 45lb at 28” to 160lb at 32” at a maximum cost of £40. Although the guide takes you through making a self bow with chased growth ring, I would actually recommend that for a first bow you consider making a laminate or a self bow turned through 90 degrees (both explained later in this guide) as they are very much easier to make So if you want to make yourself a working bow as cheaply and simply as possible then this is the guide for you. If you want to learn the traditional techniques then this may not be for you? but you could consider attending a course like the ones run by www.diyarchery.co.uk or www.tradlongbows.co.uk All the longbows I have made are the traditional medieval style of English longbow i.e.

  • Woodworking Glossary, a Comprehensive List of Woodworking Terms and Their Definitions That Will Help You Understand More About Woodworking
    Welcome to the Woodworking Glossary, a comprehensive list of woodworking terms and their definitions that will help you understand more about woodworking. Each word has a complete definition, and several have links to other pages that further explain the term. Enjoy. Woodworking Glossary A | B | C | D | E | F | G | H | I | J | K | L | M | N | O | P | Q | R | S | T | U | V | W | X | Y | Z | #'s | A | A-Frame This is a common and strong building and construction shape where you place two side pieces in the orientation of the legs of a letter "A" shape, and then cross brace the middle. This is useful on project ends, and bases where strength is needed. Abrasive Abrasive is a term use to describe sandpaper typically. This is a material that grinds or abrades material, most commonly wood, to change the surface texture. Using Abrasive papers means using sandpaper in most cases, and you can use it on wood, or on a finish in between coats or for leveling. Absolute Humidity The absolute humidity of the air is a measurement of the amount of water that is in the air. This is without regard to the temperature, and is a measure of how much water vapor is being held in the surrounding air. Acetone Acetone is a solvent that you can use to clean parts, or remove grease. Acetone is useful for removing and cutting grease on a wooden bench top that has become contaminated with oil. Across the Grain When looking at the grain of a piece of wood, if you were to scratch the piece perpendicular to the direction of the grain, this would be an across the grain scratch.

  • Marking out -Metal
    MARKING OUT - METAL ENGINEERS’ SQUARE SCRIBER Before cutting, shaping, drilling or just about doing anything to a piece of sheet metal, you should clearly mark out guidelines to help you work accurately. DIVIDERS There is a whole range of tools designed specifically to help you mark out your metal more easily. You will need to know how to describe these tools for the CENTRE PUNCH exam. Learn their names, their individual parts and learn how to describe how they are used. Click on the black squares above to find out more about the marking out tools used in metalwork. ODD LEG CALIPERS Brannock High School – Technology Department CRAFT & DESIGN SCRIBER WHAT IS IT ? A scriber – this one is double ended although they can be single ended. WHAT IS IT USED FOR ? It is basically used as a pencil when marking out in metalwork. If a pencil or pen was used to mark out in metalwork, the lines would easily rub off. The scriber scores a more permanent line on the surface of the metal which is easier to work with. Brannock High School – Technology Department CRAFT & DESIGN ENGINEERS` SQUARE WHAT IS IT ? An engineers` square is a metalwork tool used to mark out lines at right angles to an edge on metal. WHAT IS IT USED FOR ? The square is pushed against a straight side of the material (e.g. steel). An engineers scriber is then used to scratch a line onto the surface of the metal at right angles to the edge. Sometimes engineers blue (a dye/ink) is wiped onto the surface first so that the scratched line can be seen easily.

At this point strangely enough, we often talk in feet and inches. Once we take our timber into our machine shop, we naturally convert to working in millimetres and use more accurate measuring equipment! We find it easier to talk in feet and inches when buying timber and converting it, but we just find it is far more accurate to work in millimetres when reworking Above: Fat Max and Richter the timber.

Be careful as you unpack and handle them. Also be aware that although we make every effort to ease all edges, being cast and machined parts you may encounter a sharp egde or burr. If you do, ease it with some fine abrasive paper or a fine file. Some components may have a rust prevent tive oil applied. You may want to remove this oil before installing the vise. Wipe it off with a paper towel. This will leave a light film of oil on the parts that will help prevent rust and keep the parts moving smoothly. ATTENTION! Read and understand these instructions COMPLETELY AND THOROUGHLY before starting the installation or cutting into your bench. This includes instal- lation of both Crisscross Solo and Retro, and the Troubleshooting sections.

  • Marking out Steps
    Marking out Steps: The exam has begun and you have decided Piece A will be your first piece to mark out. Every piece that is marked out will follow the exact same steps. If you follow these steps you will never miss any section of the mark scheme. When you are marking out Vertical Pieces we read out measurements from Top to Bottom. When you are marking out Horizontal Pieces we read out measurements from Left to Right. The 4 steps of marking out are outline below. Follow each step for instant success Step One: Joint Locations In this step you are just isolating the locations of the joints, ie meaning where piece A joins to piece E. Common locations are typically 12, 18 and 40mm. Ensure to only mark joint locations and nothing else Step Two: Mark out Joints This is step which has already been sorted early in the exam, take each individual joint and mark out using the tri square, mortise gauge and ruler. Typical Mortise gauge sizes for joints are typically 6mm, 9mm and 10mm, Step Three: Look for Drilling Look at the current piece and check for drilling. Where there is drilling mark the exact location and draw a freehand circle around the point. Step Four: Shaping Shaping differs from Piece to Piece. Some just involve using a set square to mark an angle. Shaping should not take very long to mark out and it is usually only a few marks going for shaping. Again if you follow these exact step and apply them to each piece, then every piece will be marked out accurately Tomás Callanan M Marking Out of Piece A When marking out a Vertical Piece always read the drawing from Top to Bottom Joint Location: Measure 18mm (Use width of Piece C) to find location of Joint 1.

  • COPING SAW a Coping Saw Is Used for Cutting Curves and Awkward Shapes in Wood Or Plastic
    MARKING OUT TOOLS STEEL RULE This is used to measure a length, draw a straight edge and to test for flatness. It is marked in millimetres (mm) and made in lengths of 150, 300, 500 and 1000mm. 40 50 1mm 5mm 10mm TRY-SQUARE This is used to test that one surface is square (at 90 degrees) to another and for marking out lines square to the face-side or face-edge. Woodworker’s try-squares have a carbon steel blade and a wooden stock, sometimes with a brass face, while engineer’s try-squares have a carbon steel blade and stock. SCRIBER This is used to mark lines on metal and plastic. Hold the scriber like a pencil. When using a scriber make sure that the point is pressed into the angle between the try-square and the material. The point is made of Tool steel and has a 30 degree point angle. COPING SAW A Coping saw is used for cutting curves and awkward shapes in wood or plastic. It has a very thin blade which is kept in tension by the spring metal frame. If the blade breaks a new one can be fitted by unscrewing the handle. The blade of a coping saw can be turned to different positions. This allows you to cut in any direction. HINTS ON USING THE COPING SAW 1 Hold the handle with both hands. 2 The material should be held as low down in the vice as possible. 3 Saw at a slow pace with the blade held horizontal. 4 Always check that the teeth are pointing towards the handle.
