This changes the geometry of the levers slightly but makes the pivot design and mounting the Rotary Tool much simpler whilst still getting the same result.Ī pantograph can be used to either enlarge or reduce, for this design I have chosen to make it reduce only, for a number of reasons As we are using this for engraving with a Rotary Tool for engraving, this would make it much more complex, so to avoid this, I have moved the position of the Rotary Tool away from the pivot allowing us to use a very simple pivot. The engraving pantograph differs in design from a drawing pantograph (often used with pencils) in that for a drawing pantograph, either the tracing point or the pencil (depending on if you are enlarging or reducing) will coincide with one of the pivot locations. Very often used for drawing, this version is a small & cheap DIY version of the typically larger and more expensive engraving pantographs that can be bought. A pantograph is a simple series of levers of a set length that can be used to enlarge or reduce and existing shape.
