Tools used in dt
There is a wide range of tools used in design and technology, even a tool as simple as a ruler. (man,measuring image by Greg Pickens from Fotolia.com)

Design and Technology (DT) is a program that is first offered in primary and secondary school, and it's also a program offered in universities all over the globe. As the name states, Design and Technology focuses on a variety of different designs such as textiles and resistant materials. When working in DT, there are a variety of tools, especially in the earlier stages of construction of the designs.

Spring Dividers

Spring dividers are used as a measuring tool. They are used to mark out circles and arcs, and to step off equal lengths along a line. Spring dividers can be used with any materials, but they are mostly used to mark out metal, because they are heavier than other dividers that are made specifically to mark out wood.

Micrometer

A micrometer is a "U" shaped tool made up of an anvil, spindle, locknut, barrel and a thimble. Even though the micrometer is heavy in weight, it is the ideal tool for high accuracy marking and testing, measuring small diameters and the thickness of materials. The adjustable spindle and the locknut will secure material tightly for accurate measurement.

Tenon Saw

When working with wood, it is necessary to have accurate straight cuts and small cuts of wood. In this case, that is when the tenon saw or backsaw is used. The back part of the saw is brass or steel and is thicker than the actual saw blade, so it limits the depth of the wood cut and it also provides weight behind the saw, which increases the accuracy.

Center Punch

Used in combination with a ball-peen hammer, the centre punch is used to locate the centres of circles and arcs when marking out. It is never used with wood materials, but rather with steel and hard plastics. Once the arc or centre circle is located, the tip of the centre punch should be placed down tip first and hammered to mark out the material.

Drawing Board

Drawing boards that are used in design and technology are far more advanced than the ordinary wooden drawing board used by artists. These drawing boards are made from non-warping material and come equipped with a parallel straight edge (ruler) and two clamp strips to hold the paper in place when drawing.
