Pantograph

IMG_7053 IMG_7057

After a few initial set backs (due mostly to my inexperience of working with wood) I finally finished the pantograph I’d been planning since the last seminar.  I’m going to need a bigger drawing board to attach it to, but eureka it works!

The principle is that you draw with the pencil on the left, and the pencil on the right mimics the movements and copies the drawing larger.  The quality of the lines are somewhat dependent on how tightly the joints are screwed (it is more fluid, when they are looser, obviously) but having the wing nuts on means that the joints can all be played around with.
