Cordless drills-Screwing

Market Review

These autonomous vehicles with food, combining power, ease of use and quick-charging batteries have been highly appreciated by both professionals and amateurs-masters. We tested and you represent 11 most common models 12V drills-screwdriver.

By the way, here you can find a Cordless Tool Kit Review.

The ease and convenience in handling drills done cordless - Screwing multifunctional tools. They can quickly adapt to such a fine work, such as polishing of different surfaces.

In recent years, the market appeared portable electric tools with built-charging batteries. They are preferred because of the ease of use and relatively low prices. Technological advances in this area typically associated with advances in the production of batteries.

Power majority of portable electric tools depends on the voltage and amperage. And despite the fact that there are now tools with powerful batteries at 14.4 V, the advantage remains with the dvenadtsativoltovymi in which best combines power, autonomy, weight and convenience. Reducing time charging the battery - is also important factor. All models are equipped with our review chargers, charging for 1 hour. And some models are completed by the second set of batteries, allowing no idle during the work.

All machines are sold complete with chargers, "1 hour, but some manufacturers offer devices that allow for recharging batteries to spend 8-15 minutes.

Typical differences

The first determining factor when selecting drills-screwdriver can serve their shape and location of handles.

Classic models have "pistol" at the rear handle. For them comfortable enough to stay with zavertyvanii drilling or screws. But the situation does not ring finger too well and therefore, to retain Drill in position, it must exert some force.

Handle located at the center of gravity machines, much more convenient. They almost never tires and precision work is much higher. The horizontal position for such drills most naturally. Special mention should be Drill FESTO, received a silver medal for the best design at the exhibition BATIMAT-95. Here, the battery is located separately from the grip that provides a good balance and cumbersome, there is almost no battery.

To carry out heavy work in which Drill need to keep both hands, now under development model with a more targeted at the center of gravity handle. Battery is located, so that remained exactly the distance for the width of the palm of your hand. The surface of the grip for greater convenience elastomer covered or made rougher.

Drilling solid wood requires great speed drills and heavy pressure. Also necessary to keep strong tool, which can take up his front of second-hand.

Drills-Screwing in disassembled form

The choice in favor of ease of use determines the location of the engine, boxes of speeds, the mechanism for adjusting torque and shock motion drills - drills functions, if any. The location of these units one after another, the total for all represented here classical models, avoids loss of energy and facilitates the process of replacing any parts. The device FESTO more complex, owing to the use of new technological developments.

Other sites

Block engine, box speeds and a mechanism that regulates torque rotation drills or screwdriver, usually combined in a block section, which avoids distortion. Some models, such as, DEWALT, include the possibility of replacing coal electric motor brushes drills. Regulation of torque at most drills performed ring-screwdriver-switch. Torque and speed drill and screws have two mechanical speed, calculated on different materials.

Electronic regulator smoothly alters the speed of Bullet for accuracy in drilling. Inertia brake engine saves time: 15 minutes, you can back about 150 screws.

Automatic Cartridge, consists largely of two turns in different sides of the rings, providing caught drills or screwdriver. The mansion stands BOSCH, created for speed and convenience of fastening one fixing ring.

Maximum torque as a tool in screwing, and when drilling holes achieved when adjusting ring found in the most extreme situation.

Nickel-cadmium batteries are calculated at different amperage, depending on the power machine. Cartridges with automatic blocking drills axis very effective and easy to use: for example, in models BOSCH can dispense with one hand.

Removing and installing the battery into place - often turns out the operation. Therefore, the battery must have a form which is easy to put on her seat reserved.

Concrete Drilling

Some of these models (MAKITA, METABO I ELU) are indisputable advantage over other - a system of drills. This feature significantly expands their scope. To drill into concrete, do not forget to switch Drill at low speed.

Test results are

This test was conducted without prior drilling screw with a fairly large (6 × 80 mm) and very old and solid oak beam. Each model was wrapped five screws in different places. This allowed to set the average output of each machine (on depth screw back). Results:

* MAKITA - 71 mm;
* ELU - 55 mm;
* FESTO - 53 mm;
* RYOBI - 47 mm;
* DEWALT and METABO - 44 mm;
* BLACK & DECKER - 42 mm;
* AEG - 39 mm;
* BOSCH - 38 mm;
* PEUGEOT - 26 mm;
* SKIL - 13 mm.

Summary of technical specifications provided by wireless models drills-screwdriver.

Conclusion

The existing market-Screwing drills are divided into two categories: one related to professional and you can buy them in specialized stores, while others are considered amateur and sold in stores business.

Professional. Model MAKITA, the most powerful of the titles in our review, but too expensive. Ergonomic FESTO quickly charged with battery pack, more than meets the ratio of all "quality-price." ELU - a complicated and very powerful machine. A model DEWALT has superprofessionalny patron that enables even the most complex work.

Amateur. Quality BLACK & DECKER powerful and somewhat cumbersome BOSCH quite match their price. High RYOBI, multipurpose METABO, as well as AEG attract quality assembly. PEUGEOT distinguishes some cumbersome and lack of power. Also very low model SKIL.

Canadian Coin

The Royal Mint of Canada on Thursday issued a gold coin weighing 100 kg and the nominal value of 1 million Canadian dollars ($ 904.03 thousand).
For the first time in world practice, it is made of pure gold, 99999 samples. On the obverse, as on all Canadian coins, placed an image of Queen Elizabeth II of Great Britain work known Canadian sculptor Susanna Blunt (Susanna Blunt), while the reverse - an image with the three branches of maple leaves work senior Mint engraver Stena Witt (Stan Witten). Coin is called "Golden Maple leaf."

So far, the largest gold coin was considered to be published in 2004 in Austria a circulation of 15 pieces coin "Big Phil" - a gold coin, weighing 31 kg nominal value of 100 thousand euros, so named in honor of the Vienna Philharmonic.

Here you can find how to Grade Coins Using the Coin Grading Scale article.

Along with "The gold maple leaf", weighing 100 kg (3215 troy ounces), the Canadian Mint produces gold coin "Maple Leaf", weighing a troy ounce, and having a nominal 200 Canadian dollars. Coin is made of metal the same high sample.

With the help of new coins Government is going to return the Canadian leader, who in recent years have been lost due to stiff competition from mints from Austria, Australia, the USA and China.

After the 1979 gold coin "Maple leaf" surpassed by the popularity of the South African coin, but now large share of the market gold coins seized the Chinese "Pandas" (coins with the image of pandas (sometimes with young) on the obverse and reverse at the Temple of Heaven, weighing between 1 / 20 to one troy ounce), Australian pieces (gold coins, kangaroos, australian parrots, weighing between 1 / 20 ounce to one ounce, the nominal value of 5 to 100 Australian dollars) and American "buffalo" (a nominal value of a coin $ 50, weighing 1 ounce, depicting bison).

The new 100 - kg "Golden Maple leaf" would be used primarily for promotional purposes within Canada and abroad for activities relating to the sale of rare metals.

Choosing Soccer Gear

Leather is yesterday!

Some manufacturers engaged in the production of balls, long ago renounced the leather. And did not withstood competition from synthetics. All current model balls like Mitre, Select, Derbystar, Adidas and Nike are made of textile leather. In an age of widespread implentetion of new technologies, it was difficult to expect that retain the traditional conservative football equipment and gear. But this is not a tribute to fashion. I think balls of polymers surpass leather on all indicators. There are several objective characteristics, which can distinguish good ball from bad one and a very good - from the middle good. Primarily, of course, its strength. Not at the last spot is the ability to push off the moisture and keep the form - always remain round. Experts argue that the leather ball after first falling into the water and drying is deformed. If using scientific terminology, it will sound like: skin does not have the parameters of recovery form. This could in due course, make sure each of us. Dried after the game on the rain after the ball seemingly precise passing game could fly or jump of land at the mysterious trajectory. How many times that he put to a standstill and partners and rivals.

How to select soccer gear ...

Choosing the ball, first of all check how well the ball is inflated. Properly inflated ball released from a man tall height should jump half of the released height. An easier way: Lift the ball at head level and release. Good inflated ball will reach your belt. Then check the nipple. You can do this as follows: saliva put a finger on the nipple and make sure there is no bubbles. Make sure to check how the ball straight. This requires throw the banana ball vertically upwards (with its turning around the axis). Look whether he pulled in flight from side to side. If so, the ball is curve. Choosing the ball do not hurry. Check five to ten balls, it will allow you to verify the accuracy of the choice. A new type of soccer balls is composite soccer balls .

To serve longer

The ball served a longer time, if you follow simple rules, which, it turned out, few respects. In the first step would be to closely monitor the pressure: it must be from 0.7 to 1.00 atmosphere. Training balls pumped in the range of 0.6 to 0.7 atmosphere. And after the game should be lower than the ball to ease tension at the seams and panels. They should go and, accordingly, to restore the form. If they all keep time in voltage, they lose elasticity, pull in SELinux. The ball, which is constantly floated, wear out more quickly. Unfortunately, that many do not even think in professional clubs. When the ball is under low temperatures its need to make frost on the dry, and after the game and thoroughly wipe put sushi in a warm place. On its surface pores and is microdamages that appear after the strikes. If the ball put frost moist, microdamages accumulated in the water turns into ice, expanding, growing rift, and is in the process of destruction covering.



How to select soccer equipment

The ball of bad quality can cost less than the retail 20-25 dollars. And do not skimp on it and spend 40-45 dollars. Only no need to buy cheap "smuggling from Pakistan." In India and Pakistan now produces 95 percent of all balls manufactured in the world. Cheap forgery sew by hand almost every Pakistani village, which brought Fur graft. Qualitative same balls produce ibid., but in factories where working class masters. Working by hand, one can master the day, at best, sew two expensive ball. Factories also take orders only from the party at 20000 and more balls. As already is cheap and qualitative smuggling! Someone will think: instead of buying several pairs of good balls on 8-9 dollars each. But such people should think hard, because such a ball in the best case is suitable for children to play. Anyone who wants to receive pleasure from the game, should prefer balls at least 20 dollars.

Match balls - not to play in the yard

Professional and match balls (as, indeed, and all others except rubber) are intended solely for the game at the grassy lawn. In addition to the strength of Water-resistant and control they should be more clearly visible to players and cameras, so they have a special coating. On the field its hard abrasive quickly, and the ball loses its features. Keep in mind that even at a good coverage of the ball quickly loses attractive appearance. So what's the play on the ground? Ball is not suitable for the game on asphalt. There simply will not do. Representatives of manufacturers companies reasonably ask "Why play on asphalt? Who plays on the pavement?" We have played if there's nowhere. But in this case do not need balls to require some supernatural strength. No ball games on asphalt not endure.

There are some unnamed models, which are sold in underground crossings at a price of $ 5 per piece. Among them could get the ball - attraction, who will live and year, and two. But this miracle, repeat with another ball which is unlikely to succeed. By the way, we still love to play football in the frost. We are probably the only country in the world where chasing the ball at below 50 degrees. But it must be remembered that no firm does not produce balls, specifically at such low temperatures.

Surfboarding

Surfing - is skating in the wake of the application of technical means: surfboards different format or short flippers and special gloves (body surfing).

There are surfing on long boards, short boards, tow-in surfing (boards fitted with loops for legs and so small that for their withdrawal at sliding with waves used for towing, for example, water bikes) , Bugibording (surfing in the situation lying at the brief mild blackboard), body surfing (as used by the body surface sliding surfer, short flippers on the legs and a special glove on the hand, giving the opportunity to raise its head.

Windsurfing

Windsurfing - water kind of entertainment and sports, using special equipment in the form of small size light boards of the floating material. Classified driven sail, connected by a flexible hinge. This shell also known as windsurfing, or "sailing board".

Windsurfing can be seen as a hybrid of sailing and surfing itself. In a simplified sense, board sailing yacht similar to a small but important distinction: management is not driving, but by tilting the mast with a sail, and while driving in gliding mode and inclination to combine my own boards from board to board. The thing is that standing on a board and sail for holding a stick called vang, arrange sail on the wind in such a way that sails appeared on the strength of traction. The force, acting on the sail, the board is transmitted not only through reliance mast, but also through the feet of a surfer, resulting in a design movement. Management board sailing at the rate being offset sail forward or backward along the boards.

Athletes on the board - windsurfers - can slide on the smooth water of arbitrarily long if there is wind. They can also cut big waves until caving, and make jumps. Windsurfing - multifaceted sport: depending on the affiliation rights, one he can give slowly slipping on the water, combined with recreational in nature; for others can be explosive adrenaline sports. As is typical for modern windsurfing, it often becomes a lifestyle as a means of infinite improvement and self-expression rights.
If you want to start surfing, the thing is to pick the right board. Don't hesitate to read how to choose a surfboard for beginners articles.

Windsurfing is usually already possible under any force wind, different from zero, skiing can be divided into two main types - in gliding mode and displacement. In displacement mode board supported afloat by Archimedes force, and in gliding through the lift force to tire the flow. Gliding mode more difficult to master and to withdraw freeride board at gliding usually required quite a strong wind while the modern "formula" could glide already with the weaker wind.

RC Sail Boat

If something was lacking in childhood, then every normal person seeks make children's dreams into reality. Try everything that can be remote controlled models, caught myself thinking that RC yachts I have not tried. The reasons for this are several - the lack of sufficient lakes, seeming simplicity and, again seemingly not interested in managing yachts. But childhood dream all the harder to give themselves felt.

And the yacht was purchased - 1:24, TT Odyssey, a production company known Thunder Tiger.

The choice was due to the size of the yacht, allowing the waters to go to a small area and impressive detailing vessel. Copying details make a model on the water is indistinguishable similar to the original. And in a room on a shelf, yacht attracted to imagine his views elegance and beauty.

With complete

So, the yacht is at home. Luxurious appearance of the box with very colorful pictures, and a good set of equipment to please the whole family together with the novice captain.

In the box were:



* Manufactured housing made of white ABS plastic.
* Sails
* Mast, keel, rudder.
* A foot.
* Detail plywood.
* Detail equipment and management of solid, anodized metal, plastic.
* A reel of lasting cord.
* Glue for plastic and epoxy 5 - minute pitch.
* Colorful stickers.
* Detailed instructions for assembly.

What else is necessary:

1. Two standard machines with a force of not less than 3 kg.
2. One three-channel receiver.
3. On-board battery - assembly of the four batteries.
4. Standard switch side.

Tools used in the assembly:
Nuances assembly

To further ease the assembly model,.

Instruction is indeed needed, with the exception of explanatory drawings. The detailed illustrations and literate allow collect model without knowing the language.

Internal dimensions yacht strikes. It seems that there can play football.

Mounting side not caused any issues, but plywood frame - "motorama" is designed for standard availability were completely different - GWS mini STD and HS-715BB (for winches, specially purchased under the yacht ", and it is worth it). The issue of non-standard equipment installation simply decided - put glue on lining of the relevant pieces leftovers.

Thanks profiled stalk, all embarked on their seats on the first time. The design allows you to set and withdraw avionics very quickly.

The receiver and battery were wrapped in polythene. At the perimeter hatch was a special glue seal (there is a complete set). But as shown, to this issue positively is not enough, I carefully and meticulously - running after the first test was in the hold water. We had re-glue seal, the benefit it more than enough.



Intensive work sails in the period of training to make his case - weekend openings under the sail things had armored aluminum sleeve of ordinary rivets. On instructions pass through the ABS plastic, and as a result of holes severely divided.


Under sail

First launched in the bath was made in order to verify that the yacht is not fall that hole under the helm of the axis does not leak, that all must be done. The results of such tests calmed down, even drought vessel was as indicated in the guide.

This is the next day, and the whole family in the collection went to the nearest pond. Wind was from 1 to 5 m / c. That is all that can be said about the first tests at high water not having any feelings.

I will say only one - delight (and not only my) from the yacht was more than my other models - airplanes, helicopters, machines.

To describe the whole spectrum of emotions from the management of this article yacht little, and too many emotions. After the first diving remember the following: yacht was very easy on the course, withdraw at the slightest movement of pens and turning / turn were just a song - the yacht unfolded just diameter in length Corps model. When the mast is particularly dramatic evolution practically falls on water, causing a storm of emotions among family and reckless dose of adrenaline from novice captain. But the climb in the water for the yacht did not have to - maximum Roll protection after it regains stability rather quickly and smoothly, and it will not affect its course.


Summary

The yacht designed and staffed very well. The adjustments are minimal and necessary only when the wind changes forces.

Of the merits of models want to note the following:

* Ease of assembly and customization.
* Good manual.
* The Amazing stability and maneuverability.
* The beauty and elegance of the model.
* Good quality running.

Disadvantages:

* There were no holes under the desk, nose and stern fences.
* It is very inconvenient to change batteries and power on / off the electronics side.
* The dimensions and design features of the yacht did not allow her to participate in competitive sports of RC yachts.
* Simply cutting a hole under the in the hull boats are unsafe - with a good work they are broken sails and gradually increasing in diameter.

Yet, despite the shortcomings, the yacht would allow the dream of sails! And, at least at times, feel like the captain.



Happy sailing to you and seven feet under the keel!
