The easiest way to obtain such holes is to use an awl with a diameter of 1 to 3 mm. This awl can be easily made from a thick needle or even from a piece of piano wire, the length of which is approximately 5 cm. The needle or wire is first hammered half the length into a piece of hardwood, and a handle is subsequently made from this wood. The end of the wire remaining outside is sharpened into 3 or 4 edges. A well-made awl in this case acts like a drill, piercing the wood, it is rotated and it cuts and turns out the wood fibers, and does not just push them apart.
How to make a hole in a lamp?
It is better to work with gloves, take the light bulb in your hands and press the bulb against the sandpaper. We begin to rub the lamp on wet sandpaper, periodically add water (a couple of drops), after 5 minutes (depending on the intensity of work) a hole will appear in the bulb and, most importantly, it will be quite smooth.

DIY drill
Small-sized hand drills, the like of which you can make yourself, are best suited for this operation. To do this, two laces and a handle are tied on top to a rigid axis, which can be a steel or wooden rod, and a sharpened nail on the bottom. In the middle of the rod you need to attach a heavy flywheel, which will act as an inertial battery. In order to put this drill into action, the laces are manually wound onto the rod, and then, after installing the nail in the right place, they press the handle. The rod rotates and the nail is drilled, the pressure on the handle is stopped when the laces are completely untwisted. The flywheel rotates by inertia and winds them onto the rod again, and then stops and you need to press the handle again. Viscous wood species may not yield to such a drill, as the drill will get bogged down and slow down its rotation.
How to cut plywood - tips on choosing tools
- drill or screwdriver with drills or cutters. If the slot is closed and does not start from the edge of the workpiece, holes are drilled to insert the file;
- marking tool: compass, ruler, square, tape measure, pencil, awl for pricking the center of holes, etc.;
- a set of round and flat needle files and files or emery devices for finishing the internal planes of the workpiece.
When the workpiece has both internal and external profiles, cutting begins with the internal ones. If you start from the outside, it may be more difficult to hold the workpiece later.
Organization of the workplace is important. The master must work while sitting in a comfortable position, without bending or reaching with his hands to the place of work. For small parts, a sawing table is used.
They are on sale. But to gain first experience, it is better to cut it out with your own hands from a piece of thick plywood or board according to the following drawings:
The table is attached to a large work table with a clamp or self-tapping screws.
In some cases, it is more convenient to clamp the workpiece vertically with a clamp, then you will have to cut not from top to bottom, but horizontally, which is more convenient.
Features of working with the tool
The principle of working with a circular drill is simple. A hole is drilled using a centering drill, and then the cutters are put to work. They gradually make a narrow groove, gradually cutting through the material in a circle to the full depth.
The materials used in working with the ballerina are varied: wood, fiberboard, chipboard, MDF, plasterboard, plastic. One common point is that the thickness of the part should be no more than 15-20 millimeters. This parameter is limited by the length of the incisors. Usually the manufacturer indicates the maximum drilling depth on the packaging. If you try to drill into thicker material, you may experience problems with ragged edges.
The use of a tool with one cutter is characterized by runout. This is caused by a lack of balancing relative to the longitudinal axis of the drill. The beating will be especially noticeable when cutting large diameter holes. Cut holes using a drill at low or medium speed. When working on a drilling machine, such problems do not arise.
Also, a laminated or veneered surface can cause inconvenience when working. After passing through the decorative layer, drilling proceeds without problems.
A feature of the circular drill can be considered the ability to adjust the diameter. The distance between the cutters can be set using a scale on a rod or more accurately using a caliper. This is convenient if you need to make a hole without gaps for a pipe or round part.
The spacing of the cutters relative to the center is adjusted individually. It is necessary to align the cutting parts as accurately as possible. This will eliminate unnecessary effort during operation and extend the life of the tool.
Will need
- any product made of high-speed steel;
- marker;
- nail polish;
- nail polish remover (can be replaced with white spirit or acetone. I chose the remover only because of the pleasant smell, and it’s the same acetone);
- cotton wool;
- empty plastic container (bottle);
- salt;
- knife;
- a homemade device made from a charger and two nails.
Apply varnish to the desired area. The varnish must be applied in a thick layer on both sides. Don't forget to coat the ends thoroughly. Leave the workpiece for 10-15 minutes to allow the varnish to dry.
On the dry surface, with a marker on both sides of the workpiece, I mark the place for the hole. I choose the location arbitrarily, now I need to show how to make a hole using this method. For example, you need to install a regular factory rivet. The diameter of the hole should be slightly smaller than the size of the rivet.
Pour water into a container and add 3 tablespoons of salt. The height of the water in the container should be 10 mm less than the height of the varnished area of the workpiece.
I take a device made from a hair clipper charger and two nails. The nails will serve as electrodes - I connected them to one contact. The other contact is simply bare, stripped wire. I use a 12V charger, but a regular cell phone charger will do the job.
The stripped wire should be positive, the electrodes should be negative. We attach the positive wire to our workpiece using a clothespin. Then we lower the nails into the water.
Ballerina on wood: drill a large diameter hole
Cheap options often use soft metal or alloys, which can be brittle. Under load, parts may become deformed or break. Such a tool will not last long and it will also be difficult to achieve accuracy from it.

How to drill a perpendicular and vertical hole
Although it is sometimes necessary to drill at an angle, it is most common to make vertical holes (that is, perpendicular to the surface). In order for drilling to take place strictly at an angle of 90 degrees, it is necessary to use special guides. They will allow you to drill perpendicularly without deviating in any direction.
The simplest guides allow you to make only vertical holes, but there are also more complex designs that allow drilling at certain angles.

Each person has certain talents, some are acquired, others are given by nature. In their quest for beauty, people constantly try to make not only something new, unusual, functional, but also beautiful, aesthetic and wonderful. Working with wood is one of the oldest crafts, which remains popular and relevant today. Those who want to learn wood carving must master a lot of wisdom, understand the technique and gain experience, but this requires certain knowledge.
Wood carving originated in Rus', when, in addition to creating wooden pieces of furniture and utensils, craftsmen tried their hand at decorative and applied arts.
Due to the variety of variations in wood processing, it is worth highlighting the varieties of this skill. These include:
- through thread;
- deaf;
- brownie;
- sculptural;
- chainsaw carving.
In addition to this classification, there is also a division of woodwork into relief and volumetric sculptural carving. The technique of creating relief is considered the simplest, which is divided into the following carving options:
- geometric;
- flat-relief;
- openwork;
- blank with selected background;
- slotted contour;
- invoice.
Each technique has its own characteristics, so it is necessary to study each type in order to fully master the skill of working with wood.
DIY screw drill
For the construction of a screw drill, a rotation mechanism from a children's top is well suited. Instead of a cartridge, a pencil holder from a compass works well. When you lower the engine with the same thread by hand, the screw axis of the drill begins to rotate. With this mechanism of action, the drill head must rotate freely on the axis.
If you don’t have a top at hand, you can bend the screw of this action yourself. To do this, you will need a strip of steel, one end of which must be secured in a vice mounted on a machine or on a table, and the other end must be secured in a hand vice. When the hand vise is rotated, the strip is evenly twisted into a screw, onto which a wooden slider with a pre-drilled hole is then mounted. In order to ensure that the engine does not have any difficulties when passing the screw surface of the strip, the strip is heated and, passing through it in this state with the engine, a thread is made on the strip. To make a hat, a small wooden ball with a hole slightly larger in diameter than the diameter of the screw is suitable.
Briefly about the main thing
Drilling steel is usually not difficult, but I had to tinker with hardened steel. This material is much stronger and less pliable; a simple nozzle cannot do anything.
I used a porcelain tile drill that was left over from the renovation. I sharpened it a little, then sharpened it further as I worked. To prevent it from breaking, I regularly lubricated it with machine oil and let it rest. I didn’t want to buy a special nozzle just to make several holes, so the work was done carefully so as not to break the nozzle.
The work itself is not difficult, not much different from simple drilling. It is only important to remember the increased hardness of the material and constantly take it into account.
Write in the comments, have you ever drilled hardened steel? Did you use special drills or make do with existing ones?
