Parallel Marking Tool / Contour Transfer Tool

Sometimes a classic contour gauge is simply not the right tool for transferring contours to a workpiece. Especially in furniture making, panels often have to be adapted to uneven walls.

This parallel gauge is simply set to the point with the greatest distance to the plate and then pulled along the entire length. In this way, the exact contour is transferred to the workpiece.
 

I've uploaded different versions for different diameters of your pencils.
You will also need two M4 nuts and matching M4 hex bolts. Depending on the version and diameter of your pencils between 10 and 14mm.
The pencil does not have to have the exact diameter as specified, using a bit thicker or thinner pencil is also possible.
