Interference circle
The interference circle is used to set the cycling depth of the wheel and drive for repairs if the warehouse distances are no longer correct. The wheel distances can be defined in the event of new products. Four docks are attached opposite in pairs and can be approached or removed. A pen is inserted in every docke, which has a conical hole at one end in the middle. The cones of the wheel of the wheel and the gear are placed in these holes, and between two docks the bike comes and between the other two the gear. You can then determine the correct removal of the gear. With the circle tips on the other sides of the docks, the radius can be applied to the work board.
