Types of Nails& Glues

ROUND WIRE NAIL - This is used for general work. It is not attractive in shape and it can split wood when hammered in position
OVAL WIRE NAIL - This is a long nail and care must be taken when it is hammered into the wood. It is unlikely to split the wood.
LOST HEAD NAIL - This is ideal if it is necessary to hide the head of the nail as a punch can be used to hammer the head beneath the surface level.
PANEL PIN - A very popular way of joining woods although glue is usually included as part of the join.
TACK - Can be used for fixing textile materials to wood for example, fixing upholstery to furniture.
SPRIG - This no head and is generally used for fixing glass to glass in wood frames.
ANNULAR NAIL - The teeth of this nail hold it in place firmly. Therefore, it is used for fixing plywood and other materials.
HARDBOARD PIN - The diamond shaped head is hidden when used in materials like hardboard
CORRUGATED FASTENER - This will hold the corners of wood frames firmly together


Woods can also be joined with the help of PVA glue. Modern glues are very strong and if adverts on TV are to be believed, joints made with glues can be stronger than the wood itself.

Cascamite is a waterproof glue and is probably the most effective glue of all. It is a white powder and is resin based and should be mixed in a glass or plastic container, two parts water to one part cascamite. It must be stirred thoroughly until it becomes a smooth/creamy paste. Cascamite is a quality glue and is suitable for all furniture especially if used outside as it resists rain water. The stages involved in the use of cascamite are outlined below.

1. Pour water into a glass container.
2. Pour powered cascamite into a glass container 
3. Stir thoroughly until a smooth creamy paste is produced.
4. Apply to both wooden surfaces using a spreader or a paint brush.
5. Push the two pieces together, rubbing the surfaces from side to side. This will ensure that air is not trapped and that the glue has been spread evenly.
6. Use cramps such as G Cramps to lock the two pieces together. Leave for twenty four hours before removing the cramps.
