I work in the locomotive depot of the station Yerofey Pavlovich, produce visual AIDS for teaching assistants machinists of electric locomotives. During the work on the stand pneumatic circuits I have not found a suitable tool for sampling grooves complex profile and decided to make a cutting tool that brings together in its construction, some carpentry. Thus was born the plane-“harvester”.
Design “universal” is similar to the plane-shpuntubel, which is designed for sample of grooves on edges and plane parts, but unlike shpuntubel he’s not wooden, but metal: in addition, the convenience that the knife-cutter is supplied by the contra nut and a screw, not a wedge.
