How to make a cone splitter with your own hands?

A self-made cone splitter will helpgreatly facilitate the preparation of the material. For example, often there are problems with splitting of wood at the moment of screwing a screw or a screw. With this problem you can fight by pre-drilling the screw into the place of mechanical impact. The principle considered above is typical for helical cone wood splitters. For greater efficiency, the cone was made with an increased diameter, while reducing the ratio of the depth of thread and the diameter of the tool. In fact, the unit under consideration is a set of wedge and screw self-tapping screw. The device easily enters the wood, tearing it through the fibers due to a significant increase in the working part introduced into the tree. Consider the features and characteristics of this device.

Cone splitters can be made by handin several variants. In the first model, the design provides for a screw, which is mounted directly on the shaft of the electric motor. In this case, the unit has rather stringent requirements: the engine must have a low rpm (not higher than 500 rotations per minute), and also have a power of at least 3 kW.

In other configurationsuse of electric motors of different types. Reduction of the revolutions is achieved with the help of mechanical gears, gears of belt and chain type. On the working shaft, a pulley with an asterisk of small diameter is mounted, and on the analog of the splitting shaft there is a star of increased diameter. The approximate ratio is carried out in such a way that the design allows to reduce the frequency to 300-500 rpm. Sometimes the efficiency is achieved without a significant increase in the size of the pulley, by mounting the intermediate element and step transfer.


Cone splitters are mounted on a solid frame, equipped with a folding table for easy operation.

The main advantages of the instrument in question are:

  • Simplicity of design.
  • The possibility of making tools at home from improvised materials.
  • High performance equipment.
  • Low installation cost of the device.
  • For the operation of the unit, no additional training and special skills are required.

For the sake of justice, it should be noted thatmade cone-shaped wood splitter has a number of disadvantages. Firstly, such a tool does not cope with interlacing fibers, as a result of which knots and some logs have to be treated in a different way. Secondly, the mechanism can not be properly manufactured without the use of a lathe. With all this, the advantages of the tool override the existing shortcomings, in connection with which the tool is very popular.


Cone wood splitter with own hands (photo, instructionson manufacture are resulted more low) should provide safety at operation and high productivity. To ensure the implementation of these parameters, you must adhere to the basic requirements and recommendations for manufacturing. Among them:

  • The power rating of the electric motor should be within 2-4 kW.
  • Reducing engine rpm can be done with a reducer or a flexible gear.
  • Observe the maximum speed of the cone shaft - no higher than 500 rpm.
  • The tool must necessarily be equipped with a button-type switch, a magnetic starter and a safety (emergency) tripping device.
  • The conical shaft is mounted on bearings of the bearing type.
  • The cone must be equipped with a fixed thread.
  • If a belt drive is used, a pair of tapered belts and two pulley pulleys are used.
  • In operation, the feed of blanks is carried out with their vertical orientation, which prevents crooking, jamming of logs and deformation of the plant.

How to make a cone splitter with your own hands?

The simplest construction of the device, whichoffer some craftsmen, consists of a powerful perforator, with a cone shaft clamped in the cartridge. This solution is very dangerous and has little efficiency. The fact is that keeping it when resisting wood fibers will not be easy. If you decide to use this design, take care of securely securing the device to a solid foundation, which will allow using it according to the traditional scheme.

To produce a conical wood chipper with your own hands for 220 volts you will need the following materials:

  • The factory cone or its analog, carved on a lathe.
  • The shaft is a worker (in its quality one can apply a hub from agricultural machines).
  • Pulleys and asterisks.
  • Drive chain or belt from car or motorcycle transport.
  • Bearings with housings, for example variations from automotive cardan shafts.
  • Profile pipes made of steel (corners).
  • Metal sheet for work bench (thickness - not less than 4 millimeters).
  • Electrical engine.
  • Wiring.
  • Magnetic starter with a switch.
  • RCD.
  • Bolts and nuts for fastening.


Cone wood splitter with own hands (photo, drawingsshown below) can be made from parts of used agricultural or automotive equipment. The most difficult part in creating an element is a cone screw. With the help of a Bulgarian this knot should not even be tried to build. The spent forces and time are not comparable with the final result, which will become a miserable likeness of this screw. The analog made in this way will not even be closely related to the characteristics of the lathe model.

If the tool is operated in the mobileform, you must first acquire metal wheels. Cone splitters with their own hands with a gasoline engine or diesel analogue - the most optimal version of the mobile version.

The tools required for the work:

  • The device is welding.
  • Drill with a set of drills.
  • Saw the Bulgarian.
  • A hammer.
  • Spanners.
  • Marker.
  • Roulette.

To protect the product from corrosion, useany suitable enamel for outdoor work. Preliminary it is necessary to carefully prepare the metal surface for painting by treating the area with a metal brush or special emery nozzle on the "Bulgarian".

Before taking on the manufacture of the structure,it is necessary to compile an elementary scheme that will allow us to outline the main dimensions of the machine and the accompanying elements. A sketch of electrical wiring and wiring is also required. The diagram below shows the basic principle of machine operation.

Because, the most important detail in the designis a wedge, its manufacture should be discussed in more detail. Best of all, the part is made of tool steel. To process this material, a true professional is needed, since steel has increased strength characteristics, is difficult to process. Most often, the screw is made of St-45. This requires strengthening the threaded compartment by hardening, nitriding or carburizing.

Cone wood splitter with own hands (drawings, photogiven above) will work effectively and long only with the correct manufacturing of the cone. In the order, it is necessary to indicate that turning the workpiece is required in ½ parameters with a 5-6 mm fixed pair thread. The standard metric thread in this case is not suitable, it is much worse cut into the wood. The dimensions of the screw wedge and the size of the conicity are directly related to the ultimate size of the split.

The estimated dimensions of the frame are as follows:

  • The length is about 850 mm.
  • Width - 600 or 1000 mm (with folding table).
  • Height - up to 800 mm.


Usually a bottom-down scheme is usedelectric motor. This solution makes it possible to protect the engine working parts from chips and debris. If the engine is an internal combustion engine, it is mounted at the same level as the wedge. This configuration is more convenient during the start-up of the unit, and also allows you to adjust the ripple and refueling during operation.

When working with a screw clevis,extra care. The process is dangerous because the revolutions gain a high moment at the edge of the element. In this regard, to install the logs with bare hands in order to avoid the winding of fabrics from mittens or long sleeves. Also, the machine should be protected from excessive moisture and temperature changes.
