A Home-made Compass
Very often when we have no compasses handy, we want to draw a circle of a certain size. In such a case we can make our own compasses out of a pair of ordinary scissors and a piece of cardboard. We take the card, which should be fairly stiff, and, having made two holes in it with the points of the scissors, we put the Doints through the holes just so far as will give us the radius we require. Then using the most pointed
leg for the centre, we twist the scissors round, making a mark for the circumference with the point of the other leg. Having got the circles outline, we can then pencil-mark it in by freehand. Should more than one circle be needed we can adjust the legs of the scissors to the sizes required. The advantage of using the card is that it prevents the scissors slipping more open or closing up while the circle is being described. They are held at any radius desired quite as firmly as the legs of an ordinary pair of compasses made for this purpose.
