Revolving spindle
The radius is quickly adjusted by moving the legs. The fine adjustment of the radius takes place as usual with the middle wheel.
Adjustable double joint
The double joint enables better handling when drawing, because it is advantageous if the needle pierces the drawing surface vertically and the lead is also vertically aligned. In combination with an adapter, you can also draw with an ink pen. The mobility of each joint can be adjusted individually using the joint screw.

Extension rod
Universal adapter for drawing with a wide variety of pens
