Tip 1: How to tighten the screw
Even if you do not like to make and do something about the house with your own hands, you will still sooner or later meet the situation when you need to twist screw. A simple, it would seem, operation in some cases can cause a lot of difficulties.
You will need
- - screwdriver;
- - a wrench or a wrench;
- - Screwdriver;
- - spring and bracket;
- - Rubber tube;
- - glue or paint.
Instructions
1
Examine the head screwand choose the right tool forTwisting. If the hat has a cutout, select a cross or flat screwdriver of the appropriate diameter. Note, if you take a screwdriver that is too small, it will scroll, and too much can break the thread.
2
If the head screwbut it is made in the form of a hexagon or a square, select a suitable spanner, you can also use a adjustable wrench or, in extreme cases, pliers.
3
In order to twist screw With one or two holes instead of a slot, screw Under the Y-shaped screwdriver, screw"Secrets", created for the difficulty of unscrewing, purchase a special tool.
4
If you need to screw a large amountFasteners, use a screwdriver or a drill bit. In addition, purchase different attachments, including for screwing fasteners in hard-to-reach places.
5
In order to twist screw in a place where it is impossible to get close,Use a pivot screwdriver. Such a screwdriver can be made on its own, for this, cut a rod of a conventional screwdriver in two and re-weld the end of the spring.
6
To screw Do not have to hold your hand, put a spring-loaded bracket on the screwdriver. On the side of the handle, drill a hole, thread the pin into it and press it with a spring. When you put screw In the hole of the bracket, the spring must be firmly pressed against the tip of the screwdriver.
7
You can do even easier - find a rubberA tube with an inner diameter is slightly less than the diameter of a screwdriver. Cut a piece 3 cm long and tightly tighten it on the working end of the screwdriver, insert the head screwa. Now you can work in any position, without the help of the second hand.
8
To screw did not untwist from vibration, before workgrease it with glue or paint. If possible, rivet the end of it from the other side of the part and tighten the thread (in this case, note that the mount will not be folded).
Tip 2: How to spin the ball
The game of bowling allows you to have fun and demonstrate your skills, accurate movement calculation the ball And a direct hit on the target. The most important detail is the rotation the ball, which is not so easy to achieve, for which it takes time to train your wrists.
You will need
- Bowling ball, gloves.
Instructions
1
Put on your hands gloves with slots for your fingers, so it was more convenient to hold the ball.
2
Scroll the brushes to the left and right to slightly stretch them before throwing.
3
After making three approaches, at the last step, start the ball back, and then screw it in the throw.
4
At the moment of scrolling, sharply push the ball away from you and aim at the target.
Tip 3: How to choose a propeller
The efficiency of the boat engine is largely determined by the correct selection of rowing screw. It depends on the economy, speed and acceleration of the entire system. How to choose the right propeller?
Instructions
1
Use the easiest method of selection screw. If there is such an opportunity, compare the workersthe quality of two or three screws with different steps, alternately setting them on the same engine. Determine which screw will be more effective with a large loading of the vessel (usually a screw with a smaller pitch), and which will ensure a high speed of movement with minimal loading of the boat or boat.
2
Carry out several experiments, making measurements of fuel consumption for different loading of the boat. Define for everyone screw Optimal rate of access to planing andthe maximum speed that a ship can develop. Thus the motor should work approximately on 5000 turns in a minute at completely open throttle заслонке.
3
When checking work screw Pay attention to how much it is boilingWater from under the motor. If the engine emits a sound at the time of starting the motion, reminiscent of the vehicle's overdrive, and the movement of the control levers responds abruptly and abruptly, it is required to install a screw with a large pitch. With a poor set of speed and slow output into the planing mode, a propeller with a smaller pitch is required.
4
When choosing a propeller for a boat, consider the conditionsplanned operation of the vessel, including the permissible load. If you plan to travel light, then the screw, designed for maximum load, will make excess speed.
5
Pay attention to the number of blades screw. The highest maximum speed is provided by screws withThree blades, but they more slowly lead the ship to planing. Four-bladed propellers, on the contrary, easily go into planing mode, but are inferior to three-bladed propellers in speed.
6
To ensure a good stroke, the shape of the blades screw. Choose elliptical blades if you wantensure an optimal ratio of speed and traction. Some screws have blades tapering to the tips, which reduces friction, such screws are preferred for high-speed boats. For movement in overgrown seaweed reservoirs, a screw with blades that are twisted in the direction of rotation is more suitable.
7
When choosing the material from which the screw is made, consider that aluminum screws are preferable for outboard motors installed on small boats. They are lighter and cheaper than brass ones.
Tip 4: How to pick up the screw to the boat engine
For each vessel with a boat motor there is an optimum rowing screw. But if you use the ship in many ways - for fishing, for walking, for towing water skiers - you will need several screws. Be sure to purchase a spare rowing boat for your ship screw with a set of fasteners to it.
You will need
- - ship;
- - Boat motor;
- - propeller screw;
- - tachometer.
Instructions
1
Define the basic parameters screwbut for a boat engine. They are the diameter of the screwBut also his step. From these parameters, taking into account the engine power, the maximum speed of the boat depends. Distance in inches overridden screwin one turn, there is a step screwBut a boat engine.
2
3
Look in the instructions to the boat Motor, what maximum turns it can develop on"Full gas", with the throttle valve open. Accelerate the boat to the maximum speed. With a tachometer, measure the speed of the motor shaft, usually it does not exceed 5500 rpm.
4
Note the shaft speed atThe maximum open flap. If it is less than the recommended maximum speed, then read the tachometer readings as the maximum speed of this type of propulsion screwa.

6
When choosing screwbut to the boat Motor Adhere to a certain rule. Propellers with a large pitch are used for high-speed light boats, and with smaller steps for slow and heavy boats. Step change screwAnd the boat motor is the only way to reconcile screw with an engine and with a boat.
Tip 5: How to Repair the Screw
Most problems associated with malfunctionshard disk is solved by completely formatting it and creating new partitions. Unfortunately, this method leads to loss of important information, which is very critical for users.
You will need
- - Mount "n" Drive;
- - HDD Regenerator.
Instructions
1
If your system disk is damagedsection, try to connect the drive to another computer. After that, check the operability of the remaining local disks. If all of them function normally, just copy the important files from the system disk.
2
In a situation where you can not getaccess to the desired partition of the hard drive and you need to save certain information, use the program Mount'n'Drive. Download the installation files of the utility. Run the installer.
3
Open the main menu of the installed application. Wait for a while until the available hard disks and their partitions are identified. Select the local disk that you want to restore with the left mouse button.
4
Click the "Mount" button. After opening a new dialog, select the drive letter of the new disk and specify the priority file system. It is best to use the type with which the damaged partition originally worked.
5
Wait until the new local disk is created. Open the "My Computer" menu. Go to the contents of the mounted drive. Copy important files using the familiar manager.
6
After transferring the necessary files, close the programMount'n'Drive. Now you can use utilities designed to restore the integrity of local disks, for example, HDD Regenerator. This approach will save you from the possible loss of important files, allowing you to perform any manipulation of the hard drive.
7
It is worth noting that sometimes it's easier to reinstalloperating system and run a program that determines the bad sectors. Use this option if you do not need to save the structure of an existing partition.
