PENTOGRAPH - DIY kit for Students

Pantographs are used for reducing or enlarging engineering drawings and maps and for guiding cutting tools over complex paths. Artists specializing in miniatures use panto graphs to achieve greater detail. A panto graph (Greek roots παντ- "all, every" and γραφ- "to write", from their original use for copying writing) is a mechanical linkage connected in a manner based on parallelograms so that the movement of one pen, in tracing an image, produces identical movements in a second pen. If a line drawing is traced by the first point, an identical, enlarged, or miniaturized copy will be drawn by a pen fixed to the other. Using the same principle, different kinds of panto graphs are used for other forms of duplication in areas such as sculpture, minting, engraving, and milling.

Lastly, select an original drawing that you want to trace. Place a blank piece of paper under Drawing Surface. Now trace the drawing, follow it with the tracer needle by moving the pencil point maintaining light fingertip pressure and you will see another picture being drawn at Drawing Surface. Now you can easily trace complex drawings and make copies for your needs. You will see that you can easily enlarge or reduce the size of the drawings made
