Wooden Pantograph 35 cm.

Reference: 1250016
Drawing device that allows you to copy a figure or reproduce it to a different scale, either higher or lower.

To achieve different scale we must change the distance between the articulation points, while always preserving the condition of parallelism between the rods, two by two.

To draw, pivot must be fixed, and you have to move the reference point upon the original drawing. A pencil located on the copy point reproduces the image on a larger scale, which is determined by the points of distances P-PR y P-PC. By changing the reference point for the copy point, the image comes reproduce to a smaller scale.
