When drilling large diameter holes (20-30 mm) in a tree, the required drill or perk may not be available. In this case, first drill a hole of a smaller diameter, and then insert a flat steel washer (preferably a new one) into the rotary chuck and pass the hole again. This method is also applicable for countersinking holes.
If you need to drill a lot of holes in wooden parts at right angles, then take a cube of solid wood, drill a reference hole in it with great accuracy. And then use this conductor to work like this. A cube put on the drill will serve at the same time as a limiter of the drilling depth.
Corking capsules from lemonade or beer is a good substitute for a drill, when it is necessary to drill compass needles in the wood holder, then reduce the risk of breaking it when the fiber material or plaster has a hole with a diameter of about 20 mm. Pierce the plug, put on the bolt, securing with two locknuts, and drill.
It is difficult to make a hole in layered plywood, it splits. Take the steel tube of the desired diameter, grind the cutting edge inside with a round file and cut the teeth with a trihedral file. Insert a wooden cylinder with a nail without a hat inside the tube. During operation, the end of the nail, protruding 1-2 mm, is the guide.
So that when drilling small parts from sheet material they do not scroll, we recommend that sandpaper be placed under them.
If you fix a drill with a diameter of 0.8-1.1 mm, you will drill holes of small diameter in a tree, textolite, and plastic.
There are many devices for cutting holes of large diameter in sheet material. plastic, plywood, chipboard, etc. You can use the design: a bracket bends from a strip of steel with a thickness of 2-3 mm, its ends are screwed in, and a hole is drilled in the center, then the bracket is put on a bolt with a sawed-off head. For operation, the device is clamped in the chuck of an electric drill.
Cutting a large hole in the sheet material can be done in a simple way: clamp a nail (it will serve as an axis) and a piece of drill (it will be a cutter) in a vice. The circumference is cut through the rotation of the sheet around the axis.
A circle of any diameter from plywood can be cut precisely, accurately and quickly with a wooden plank and two pointed nails driven into the plank.
The pencil sharpener cutter (sold separately) can be used with success for boring holes in wood and plastic. It is fixed in an electric drill cartridge and the edges of the hole are machined.
A potato peeler in the hands of a craftsman is an almost ready tool for processing rounded holes in plywood. You just need to sharpen its cutting edge.
When drilling a board or plywood, remove burrs at the same time, for which string several rings of dense felt onto the drill.
It is easier and faster to drill concrete with a carbide drill sharpened asymmetrically. However, we still recommend planning and starting holes with a drill with a usual sharpening.

The easiest way to obtain such holes is to use an awl with a diameter of 1 to 3 mm. It is easy to make an awl from a thick needle or even from cutting a piano wire, whose length is about 5 cm. The needle or wire is first hammered into a piece of hardwood for half the length, a handle is subsequently made from this tree. The end of the wire remaining outside is sharpened by 3 or 4 sides. A well-made awl acts in this case as a drill, piercing the wood, it rotates and it cuts and twists the wood fibers, and does not just push them apart.
Small-sized hand drills are best suited for this operation, the likeness of which can be made independently. To do this, two shoelaces and a handle are attached to the rigid axis, which can be a steel or wooden rod, and a sharpened clove from the bottom. In the middle of the rod you need to fix a heavy flywheel, which will act as an inertial battery. In order to bring this drill into action, the laces are manually screwed onto the rod, and then, having set the carnations in the right place, press the handle. The rod rotates and the stud drills, the pressure on the handle is stopped when the laces are completely untwisted. The flywheel rotates by inertia and winds them again on the rod, and then it stops and you need to press the handle again. Viscous wood species may not succumb to such a drill, as the drill will bind and slow down.
Do-it-yourself 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 for a compass is well suited. When the engine with the same thread is lowered by hand, the screw axis of the drill starts to rotate. The head of the drill with such a mechanism of action must necessarily rotate on the axis freely.
If there is no top at hand, the screw of such an action can be bent independently. To do this, you need a strip of steel, one end of which needs to be fixed in a vise, mounted on a machine or on a table, and the other end to be fixed in a manual vise. When rotating a manual vise, the strip is evenly twisted into a screw, on which a wooden slide with a pre-drilled hole is then mounted. In order to prevent the engine from experiencing difficulties when passing the helical surface of the strip, the strip is heated and, passing in this state along the engine, a thread is made on the strip. To make a hat, a small wooden ball is suitable, in which a hole is made in diameter slightly larger than the diameter of the screw.
