What you can make from a drill with his hands

What you can make from an old handheld drill

We are part of nature. How harmonious each of us feels in the garden, in the dacha or in the homestead. Exactly mowed lawn, weedy seedbeds please our eyes. But it’s not easy to achieve such a result by hand. A aching back, grass-cut fingers can be excluded from your life, if you apply ingenuity and with the help of primitive tools to construct a garden trimmer for grass, or lawnmower, as we are more accustomed to call this tool.

Make such a trimmer for the grass can be very easy. To do this you need:

Creation of a tool literally takes a couple of minutes. Two blades are screwed to a body polishing disc. But they’re not screwed on tightly, but they just “wiggle” freely. This version of the connection allows the blades not to break, but to lay when in contact with an obstacle. The disk itself with the blades already fixed is installed in an electric screwdriver, of course with the cutting tool downwards. The tool is ready to work!

Such an amateur grass trimmer will allow you to mow grass in hard-to-reach, narrow places, in between rows or where there are partitions. Of course, the undoubted “plus” is the saving of time and effort you spend on manual weeding. There are only two disadvantages. you still have to bend over and cut the grass in this position, and then collect it manually.

There is also its own specifics. You have to “fight” tall grass with this tool in a special way. First cut the top, and then the base, as long grass can get tangled on the base of the disc. Then it must be removed manually.

Nozzle on the electric screwdriver

After some thought, you can make an attachment for an electric screwdriver.

Such a simple design nozzle can be created without too much difficulty.

The good thing about this idea is that you don’t need to spend money on extra parts. Everything you need is in the drill. Need only a lathe, angle grinder, welder and of course. an electric screwdriver, the nozzle on which we will now make:

  • Remove the two covers from the body of the drill. Unscrew the thrust part.
  • Knock out the cotter pin from the small gear and remove it from the shaft, on which the drill chuck is mounted.
  • Using a sharpening machine, bore the tapered tip of the shaft to 10 mm.
  • Insert the shaft back into the drill body, put the pinion on and cotter pin.
  • Cut off the threaded shaft on the right side with an angle grinder.
  • Screw the rubber grip (improved version) into the body on the right.
  • Cut the threaded part of the big gear shaft.
  • You need to weld the head to the big gear shaft.
  • Screw the two covers back onto the housing and lubricate the gears with special graphite grease.
  • The nozzle is ready to use!

Self-made mechanism allows you to screw in and out bolts and nuts in hard-to-reach places. Increases torque by 6-7 times. Since the nozzle has a longer length than a simple electric screwdriver, the tool can be used in the household, for furniture assembly, car repairs, if the wrench connection cannot be reached by other means.

Tool for stripping rusty male threads

The workpiece is partially cut in half lengthwise. Then it is welded to a piece of strip. On the sides of it are welded nuts.

After that, a piece of metal saw blade is inserted into the cut of the workpiece, with holes around the edges. It is drawn by springs to the welded nuts.

Now by inserting a rusty stud between the angle and the blade, and rotating it with an electric screwdriver, the thread can be cleaned of corrosion.

From an electric toothbrush

An interesting option is a mini drill, which can be remade from an outdated electric toothbrush.

The motor and gear fitted to it is capable of delivering enough torque to drill a hole in thin metal, plastics or computer boards.

The main thing that will be required from the master is to replace the cleaning head on the shaft with the same engraver or collet chuck. It is important to determine the diameter of the shaft before you purchase the chuck so that the chuck will lock securely to it. sometimes this will require sawing the fixing screws.

Reference! Many brushes, including obsolete models, are already equipped with a regulator of rotation speed and are sold as a set with a battery device.

Assembly

All removed and disassembled drill assemblies must be placed in their proper places. The photos that you will be looking at in the reverse order of disassembly should help you with this.

The final step is to check the final fastening of all mechanisms. Note:

Then the removed cover is placed in its place, taking into account the mechanical locks and secured with the fixing screws.

The drill is complete but must not be put immediately under load: always check the quality of the assembly.

Design

The traditional version of the lathe includes the following basic units: electric drive, bed (base), headstock, tailstock, slide. An electric drill is used as the power source (electric drive) of the homemade lathe.

Stand

Designed to house all other components. It bears all the work load. Therefore the base frame must have a safety margin. The structure deforms minimally during machining and ensures accurate parts.

The classic lathe bed is a technologically complex component. Its surface, mating with other assembly units that are part of the lathe, is made with high accuracy requirements. During its technological processing special high-precision equipment is used.

The precision of the machine tool depends largely on the quality of its bed. Therefore, it is an expensive component. In the self-made version, the requirements for the final product are much simpler, the bed (base) can be made from any available materials that do not require expensive machining.

Front headstock

In the headstock of the lathe is an electric motor with gearbox and control unit. Its function is to transmit rotation, as well as to support the workpiece for machining. Another name for the headstock is the spindle headstock, because the main part of this unit is the spindle. It is a multistage shaft with a bore inside that rotates in adjustable precision bearings.

On the side of the working area is a flange, to which the three-jaw self-centering chuck is mounted. Various clamping devices, e.g. a collet, are installed through the holes in the shaft. The fastening of the workpiece in the home-made machine tool is carried out using the drill chuck of an electric drill, i.e. has significant limitations.

Control unit of a standard lathe allows selecting almost any option for the processing of workpieces in accordance with the technological process. In the self-made version, the function of the tailstock is performed by an electric drill together with the base on which it is mounted. That is why the choice of the mode of workpiece machining is limited by the functional capabilities of the power tool.

Rear headstock

The workpiece is clamped on both sides to provide the necessary rigidity during machining. This is particularly important for long workpieces. Therefore, a tailstock is located opposite the headstock. In the body of the tailstock there is a thrust or rotating center that serves to clamp the workpiece. Cutting tools such as drills, countersinks, reamers can be installed in the tailstock.

Support

The lathe’s headstock provides the tool feed to the machining area. Usually the tool is fixed in a special fixture (toolholder) that is placed on the slide. Kinematic scheme of the slide allows him to move both longitudinally and transversely relative to the axis of the spindle. The tool can be set at an angle to achieve tapered surfaces.

The working tool of the lathes is set in motion both manually and with the help of mechanical devices. On homemade lathes, the tool feed into the cutting zone is mainly carried out by manual physical force.

What to make from?

There can be several variants of the execution of a mini drill, made by your own hands. Your imagination is only limited by the availability of the necessary components. Optimal is considered a portable drill, made with their own hands from the motor from household appliances. A wide range of motors can be used.

Since we do not have to “reinvent the wheel”, since the blender already has its own body and motor, we have made a separate description of making a drill from this device at home.

  • the housing and the electric motor from a blender;
  • Collet chuck for a drill (you should buy it at a hardware store);
  • switch or pushbutton.

The scheme for making our home-made device is as follows:

  • disassembling the blender housing;
  • we insert the switch into the housing, then connect it to the electric motor;
  • now we need a collet chuck, put it on the motor axis;
  • In the casing we make a hole under the size of the fixture for clamping;
  • Assemble the casing, and our homemade mini drill is ready for use;
  • put a drill bit or an engraver bit in the jig and use.

However, such a device is enough to do simple work, such as drilling holes in circuit boards or engraving parts.
