How to use - Pantograph
If you place a drawing on the board and follow its lines with the wooden pointed pin, the drawing will be reproduced 1,5 times bigger by the pencil.
By reversing the pencil and the wood pin, you can decreasing 1,5 times the drawing's scale.
If you change the distances between holes (here 15 and 22.5 cm), the scale is modified.
