1. Joining Materials Theory. Knowledge and Understanding.

2. BRIDLE JOINTS are used when a light frame is needed. for example, a picture frame. One part of the joint fits into the other part and is glued permanently in position. BRIDLE JOINT MORTISE AND TENON JOINT Can you name the joint and its use. MORTISE AND TENON JOINTS are used when making tables or cabinets and they are very strong when glued together.

3. DOWEL JOINTS can be used where almost any two pieces of timber are to be joined. DOWEL JOINT LAPPED JOINT Can you name the joint and its use. LAP JOINTS are very common and can be seen in furniture and box constructions such as jewellery boxes.

4. MITRE JOINT is a joint made by cutting the wood usually at a 45° angle, to form a corner, usually a 90° angle. It is often used in making picture frames.. MITRE JOINT DOVETAIL JOINT Can you name the joint and its use. DOVETAIL JOINTS are very strong because of the way the ‘tails’ and ‘pins’ are shaped. This type of joint is used in box constructions such as draws, jewellery boxes and cabinets

5. In commercial production traditional wood joints are being replaced with new methods which are quicker, stronger and can be flat packed

6. These are blocks, brackets which allows furniture to be put together and taken apart easily. ADVANTAGE Very fast and easy to use, cheap and can be flat packed. DISADVANTAGE Not as strong as traditional joints or glues and unattractive.

9. There are TWO main ways of joining metal PERMANENT or SEMI PERMANENT Bolts are used to join pieces together either permanently or temporarily. Many steel structures, including buildings, are simply bolted together. Pop riveting is a technique that is used to join thin pieces of metal. The pop rivet pliers are used to pull the pin through the rivet and as this happens the rivet is deformed slightly so that it joins the metal or plastic pieces. This is explained in detail below. This technique is used where the metal or plastic is thin and where the joint does not have to be very strong. It is ideal for joining aluminium or even thin sheet plastic.

10. Clean away dirt and add flux Turn on brazing torch Heat up join and add brazing rod The melted brazing rod cools and forms a joint between the sheets of metal

12. ACRYLIC CEMENT (TENSOL CEMENT) Watery, clear liquid, isn't particularly strong, ideal for joints which are not going to be moved. Hot glue gun - can be used to join a variety of plastics. This glue usually gives a semi-permanent joint as surfaces glued together can sometimes come apart. The glue is a type of plastic that melts when hot and solidifies when it cools Super glue - joins plastics together, very quickly. Great care must be taken when using this type of glue as it will just as easily glue fingers together.. Contact adhesive - adhesive is applied to both surfaces and when the surfaces appear to be dry they are pushed together. If the two pieces of material are left for a number of hours, they are virtually impossible to take apart. A good example is ‘Araldite’
