A self-made regrover will help facilitate tire trimming when creating home-made all-terrain vehicles, for example, on the basis of a scooter or walk-behind tractor . Alternatively, you can strip the rubber to the cord, but this will not give an aesthetic appearance, although it will radically lighten the element. The second way is to use the controller to cut the tread. The factory model will fly into the penny. Given that it will be needed for a short period, you can make the device yourself. To perform the work, you need a welding machine with a current regulator from 70 to 220 A.
Where to begin?
Consider the first version of the method of how to make a regruver with your own hands. The body is made of dry birch growth (burls). Using a gasoline or electric saw, the workpiece of the desired shape is cut, and then processed with emery material. You must purchase two thick copper contacts. To simplify processing, they can be further burned. On one side, the workpiece is adapted to fix the knife. You can attach the device to the screws.
Welding wires are used as wiring, which also heat up during operation. For their output, several holes are drilled in the housing, one end is output directly to the terminal, the other end is on the power key, which can be made from a button from a drill or other electrical toolbox. It is desirable that the regulator be equipped with a return spring in order to avoid dropping.
Production of knives
A home-made regrover will require a cutting element. These parts can be made from a hacksaw blade or scythe. The best option would be a band saw with a thickness of at least 1 millimeter. The width of the knife is 5 mm. The rated current during operation can be set from 70 to 80 A. When cutting, it is necessary to control the operation of the machine, since smoke will appear in the event of a traffic delay.
The formation of the cutting part begins with pieces of the blade of the desired size and suitable configuration. It is sharpened on one side and bent in the direction opposite to sharpening. When carrying out the manipulations, it will be necessary to heat the future knife with a gas burner until red. Particular attention should be paid to sharpening, as it plays one of the key roles in the work. If a bet is placed on a minimally thin blade, its width should increase in order to withstand the acting current in electric welding.
The disadvantages of the Nordica unit in the manufacture of a do-it-yourself regrouver include a cooling fan connected to the secondary winding. For this reason, when you turn on a homemade device, it just stops. There is only one way out: to work for a short time, taking into account the fact that the welding machine is equipped with protection against overheating.
Homemade regruver: method number 2
This tool is designed to conduct experiments on trimming automotive rubber. The design of the device includes a step-down power supply from 220 to 30 volts. It is necessary to remove the trance from it. Then you should remove the secondary braid and wind a 30-sq. Multicore copper cable. When rewinding, the received power output must be taken into account. Ideally, it should be 2.3-2.5 V. The parameter is selected using a voltmeter.
For a convenient start, you can use various devices. In this case, the reggrover for cutting the tread is equipped with a pedal from an old sewing machine. After several workouts, with its help, you can adjust the voltage on the primary and secondary winding. All filling is mounted in a standard factory building.
Handle with cutter
It is necessary to draw a knot schematically, and then make the corresponding template from cardboard. The device itself can be cut from chipboard. Again, we use a hacksaw blade or other suitable product as a knife.
For a cutter, a clerical blade is suitable for a trance of 100-200 watts. If desired, the unit can be simplified to a halogen electronic model with a transformer. For this, one turn of thick wires in the amount of four pieces of 1.5 kilowatts each is enough. Such a system is fixed in copper contact with the hole and bolt clamp.
DIY soldering iron regruver
For domestic use, a fixture of indirect heat is suitable as a tool for cutting tread on various tires. The design includes a powerful electric soldering iron (at least 100 watts of power) and a cutting tool with a set of blades, the width of which varies from 5 to 8 inches. This size is ideal for inserting instead of the main element of the glow of the soldering iron.
Regruver knives can be made independently from a clerical knife and the base of a used screwdriver, or purchase a special ready-made kit. The hardened blade of the considered tools lends itself perfectly to bending and drilling, which facilitates its processing after heating on a conventional gas burner.
It is important to hold the blade nozzle securely in the body of the soldering tool. To do this, remove the retaining ring, cut four sockets under it and pull off the installed nozzle with a clamp.
Recommendations
If during operation there is a smell of burning rubber or an overheating of the device is noticeable, it must be disconnected from the mains. The accumulated energy will be enough to continue processing for several minutes.
Grooving should be done according to the old pattern of the tread of the wheel. At a minimum, this figure should be from three millimeters. It is not permissible to strip the rubber layer to the cord.
On the front axle, you need to mount new tires, and use the resuscitated elements at the rear or on the trailer.
Finally
The above describes how to make a regrover on your own in several ways. In conclusion, I want to note that this device is an aggregate for tread cutting at home. It may be needed at home no more than once a year, so acquiring expensive factory equipment is not always rational. It is worth noting that the factory models are equipped with a refractory handle and have several modes of operation. They are designed for professional use, and for home use do-it-yourself recruvers are quite suitable.
