Ski mounts - one of the most important parts of the skier's equipment, which will depend on the life and safety of an athlete . Therefore, they must be properly positioned and fixed. This will be discussed in this article.
How to determine the center of gravity?
First of all, it is necessary to locate the point of application of the total gravity. This is notable. Wooden or plastic ruler put an edge on a horizontal surface. Then it is necessary to put a skiing side to it up, the line must be moved over the surface until the balance between the heel and the ski toes is established.
When it is possible to achieve this position, the site is noted with a pencil or marker. At the same time, it is important that the line coincides with the place through which the axial fixation of the bracket is passed.
You can use another method of determining the center of gravity:
- Ski lift, placing my finger at about its center;
- You must find the point on it so that the ski is parallel to the floor or the table and did not lean.
The center of gravity needs to be determined to ensure convenience of movement and in order not to have a "advantage" during movement.
Marking
After resolved the question of finding the center of gravity, the stage of labeling holes is underway. To do this, it will be good to use the conductor, it is easy to determine the location of the holes for fasteners. If this device is not available, then take a template made of cardboard. Most often it comes in a set with inventory. And if it was not found, then you can search the template in electronic form and print yourself. Nothing terrible if there is no paper, because the markup can be done using the usual sequila . To do this, apply fasteners in such a way that the exact location of the center of the masses agrees with the strip, where shoes are fixed. In the SNS system, the axis point is exactly under fastening. The holes are located in front of the axis of the center of gravity (in NNN). Through the holes fasteners make a bright marker of the label.
Installation Instructions
The parameters of the fastenings of cross-country skiing depend on the features of the skiing on which they will be used. When driving along the tracks located on the plains, important conditions are simple design and small weight. To understand which attachments are suitable for the skate stroke, you should get acquainted with their main species. On fasteners that are designed for ski ski, rubber band (flexor) is tougher, and for classic - softer. In the first case, if the flexor is soft, then skis will hang out. In the classic course, the flexor is needed soft so as not to interfere with repel.
Fastenings are 3 species:
- Systemic : NN Rotofella (and modern version of NORDIC INTEGRATED SYSTEM), SNS Salomon;
- Hard - Nordic Norm 75 mm, they are also called the RANT, this is a standard fastening system;
- semi-rigid - Strap, buckle, gum.
Hard and semi-rigid fasteners are ever less common. Hard - these are fasteners consisting of 3 spikes, which are located on a metal plate. She has a spring meadow. The advantages of rigid fasteners include: a low price, an ideal option for teaching children. From the disadvantages, it is possible to note difficulties when equipped, the left and right fasteners are poorly separated, a very many poor-quality fakes are sold, and the shoes that fit the fasteners are now producing less and less.
Among the positive features of the SNS fasteners, the following can be called: reliability, quality of models, you can pick up any models not only for an adult, but also for a teenager or child. Among the disadvantages, it should be noted the need to use special shoes - shoes with a rod that enters the fixation groove intended for this. In addition, this shoe is difficult to find on sale. These attachments are suitable for use on the ski access, which was processed by a special machine to prepare the track. This tracked car is called random.
The most popular models, the convenience of which were appreciated by skiers, are NNN . On such fixation occurs with the help of screws or puts on with the "Salazok" kit. Among the advantages of such models are the following: easy selection of suitable shoes, the ability to select fasteners (automatic or manual), low price with good quality, you can choose models for adolescents. Unfortunately, water falls inside, the mount freezes at a minus temperature.
These 2 fastening systems have a groove in order to fix the metal rod in the front. It must be fixed with the axis of the center of gravity. In the center under this groove is still one - longitudinal. Here it is necessary to make the coinciding with the line on the upper side of the ski.
Much to facilitate the process of placing fasteners made it possible to use the new NIS system - this method is the easiest. Skis with a special platform. To install the mount, you need to start it on the guides until the characteristic click sounds. The backbone is also installed on the guides. Fix it using the key included in the product kit.
This system allows find the best mounting position for all skis, depending on the weather and the steady state of the ski slopes . You can adjust it as needed, you can even directly during training. It uses the same key. With it will move the fixture to the required number of "clicks" and lock in a comfortable position.
Skiing consist of two separate parts and the plate under the toe, whereby the friction shoe decreases noticeably. The front part is responsible for the disconnection side and the back - over detach when moving vertically. All models indicators front and rear coverages are the same. Therefore, the shoes fit all companies.
Depending on the athlete's body weight marker fastening regulate . You also need to focus on the experience of the skier and the way he drives. If a person when riding aggressively slips, the ski has to be stationary at the site of attachment.
Bodyweight divided by 10 to determine the time of protective operation. If the skier - beginner, obtained from private must subtract another 1-2 units . The greatest level of control ski bindings - about 3-4 units from the originally obtained by dividing numbers.
Maximum force some manufacturers indicate in kilograms. Then it is necessary to subtract the 20-30 kg.
To find the correct unit mounting skis, you need to examine the scheme presented on the website of the manufacturer. This information is in the manual that comes together with the fastening device. If you have no experience in the selection and purchase of sports equipment for skiing, do not make a purchase alone, and it is better to ask advice of the seller consultant.
To install the attachment, you must consider many factors. If you mount the device on the ridge skiing, they need to move forward or backward relative to the balance line. When shifted to the front part, the directional stability is increased, and if the rear - is possible to improve sliding.
Some current models have an axis that is offset from the back of the nose shoes. It is necessary to consider installing fasteners.
If confidence is not present and there is a fear of damage of fastening not cheap or skiing, it is best to seek professional help. In stores that sell sporting goods, and workshops can help deal with this problem.
, You need to prepare if it is decided to fix myself:
- an adhesive composition;
- awl;
- pen alcohol-based;
- screwdriver;
- line;
- drill.
drilling holes
Before you start to drill depressions need to correlate the interval between the holes located on the fixture, with the distance between the marks that were applied in the previous step (markup). Most often, the instructions indicate in detail how the distance to the depth must be screwed screws. What length will need a drill, there is also written. The drill for SNS is used 3.6 mm for nnn - 3.4 mm. As for the depth of the holes, in both cases - 10 mm. If you use the bar when drilling, you can achieve perfect verticality when creating holes.
If the corresponding length of the rotational cutting tool was not found, then you can take any other. Its upper part can be wrapped with a tape, leaving the protruding the desired length. After that, set a small speed on which the drill is running, and in places where there are markups, drill holes. When the holes are ready, you need to remove all dust. After that, they need to pour with carbon black glue. This will help securely fix the screws and ensure waterproofing and strength. It should not use the epoxy resin, since the solvent that contains in it can damage the ski material.
Assembly
After that, you need to apply the device to the obtained holes. Screws are uniformly spinning with a screwdriver or cross screwdriver. It is necessary to carefully observe the displacement of the longitudinal axis. Before screwing for NN 75, you should make sure that the centering accuracy should be accurate.
You can go to ride after the adhesive dry well. No need to use the product at least a day.
