Dividers are used for scribing circles, arcs and for transferring and stepping off distances.
Dividers are available with firm joints and spring joints. The measurements are set on the dividers with a steel rule. The sizes of dividers range between 50 mm to 200 mm.
The distance from the point to the centre of the fulcrum roller (pivot) is the size of the divider.
For the correct location and seating of the divider point prick punch marks of 30° are used.
The two legs of the divider should always be of equal length.Dividers are specified by the type of their joints and length.
The divider point should be kept sharp in order to produce fine lines. Frequent sharpening with an oilstone is better than sharpening by grinding. Sharpening by grinding will make the points soft.
