Curve plotting apparatus and its method of use
An apparatus for plotting a curve 10 comprising a pair of arms 12a, 12b capable of movement, and means for positioning the arms, the position of the arms capable of defining at least three points A, B, C of the curve R. The proximal ends of each arm may be connected by connection means 16 which enables movement of the arms around a centre pivot point. The connection means may include an aperture 18 at the centre pivot point and the distal ends of each arm may include an indent 14a, 14b, providing the three points of the curve. The apparatus may further comprise offset arms 20a, 20b rigidly fixed to the pair of arms, each offset arm being positioned generally equidistant from the connection means and a connecting rod 22 positioned between the offset arms for enabling adjustment of the angle formed between the pair of arms. The curve may be a railway track layout. Also provided are an apparatus for setting a curve in a model railway track, comprising the apparatus described above with a track guiding means situated at each of the at least three points on the curve, and a method of plotting a curve.
