Constructed from 2 mm thick steel plate, this efficient tool helps to find the centre of branches, round and irregular workpieces, ranging from few millimetres to 27 or 31 cm in diameter.
The two steel supports on the bottom side of the plate provide a reference point and make this device stable.
Moreover this device features numerous holes and semi-holes to control the diameter of the workpiece and its cylindricity. The slots on the right side of the plate are used to check the angle of the tools to be sharpened. There is
also a 75è caliber on the right bottom corner to verify the dovetail profile of the workpiece to grip the chuck.
