For professional lock insertion, you will need a set of high-precision modern electric tool. The second technology, which can also be called "artisanal", involves the use of only a hammer and a chisel. Everyone has the right to decide for himself how to embed the lock in the door. It should only be immediately emphasized that the result of an artisanal installation can seriously upset the owner of the home.

For high-quality and correct insertion of the lock, you will need a manual milling cutter. It is this tool that professionals use in their work. Manual milling cutter provides high accuracy and quality of preparation of seats for lock elements. An important point when performing work is to save decorative coating door leaf. It is the use of a tool with a high rotational speed of the cutter that allows you to achieve this result.

Except manual router you will need a hammer and chisels different widths. The latter will be useful specifically for the artisanal lock tie-in technology. With their help, you can prepare the landing recesses for the bar of the locking system. The result of working with such clumsy tools will largely depend on the skills and accuracy of the master. In addition, you will need an electric drill or screwdriver. They are used to create holes for door handles, as well as drilling recesses for the lock itself.

It is also necessary to prepare a flat and Phillips screwdrivers. It is these simple and reliable tools it is better to use for tightening the screws with which the handles and the lock are attached. If you use a screwdriver, then there is a possibility of damage to the decorative coating of the door if it jumps off the screw. You should also prepare a set of drill bits for a drill. With their help, you can cut out seats for the installation of the lock. In addition, when installing the locking mechanism, you will need a tape measure and a simple pencil. The following will detail how to insert the lock into the door.

Insert door locks: instructions for work

After preparing everything you need to install the lock on the door of the tool, you can begin to work. The first step is to decide what position the door will occupy in the installed state. To decide on which side the hinges will be fixed, and on which the lock is embedded, you can attach the door leaf to the wall near the opening. After that, it is necessary to mark the places for inserting the lock. This process is simple and even a beginner can handle it. It follows from the lower edge of the door leaf with a tape measure to measure 800-900 mm. At this height, as a rule, the installation of locks and handles on the door is carried out.

After that, at the end of the door leaf, it is necessary to designate the center. For this, two marks are used, through which a straight line is drawn. It will serve as an indicator of the location of the axis of installation of the locking mechanism. It is this line that will be the main reference point in the implementation further work. After that, it is necessary to measure the length of the part of the lock that will be inside the door leaf. The resulting measurement result is divided in half. This value must be set aside from the marked installation point door handle along the previously drawn axis in both directions. The resulting segment sets the boundaries of the recess for the installation of the lock.

Now you need to drill the mounting hole. The first step is to measure the width of the part of the lock installed in the door. Based on this indicator, you need to choose the right drill bit for the drill. It should be a few millimeters wider than the measured dimensions of the part of the locking system cut into the door. After that, using a special drilling method, a recess is made under the lock insert. Doing it is necessary in the following way. First you need to install the drill on one of the extreme marks that limit the installation site, and go deeper by 1 cm.

After that, the drill moves a distance equal to half its diameter, and again a recess of 1 cm is made. Thus, it is necessary to make holes along the entire length of the lock installation site. Now you should return to the first recess and drill another 1 cm. The procedure is repeated for other holes already made until the required depth is provided for installing the lock. After preparing the landing recess, insert the lock into it and mark the sweat for the decorative part of the locking system with a pencil. Now the lock can be removed from the door leaf. The next step is to cut the sweat.

As mentioned above, it is best to carry out this operation using a manual milling cutter. In this case, you will get a neat recess. If the router is not available, you can use a set of chisels and a hammer. Before you start cutting out sweating, notches should be made along the entire previously drawn contour. For this, the chisel is placed perpendicular to the end of the door leaf and depressions are made with gentle blows of the hammer. Now it is necessary to remove the material of the door leaf to the thickness of the decorative strip of the locking system. In this case, work should be carried out as carefully and carefully as possible so as not to damage the decorative coating of the door.

At the final stage of installing the lock on the door, it is necessary to drill a hole for installing the door handle. To do this, using a tape measure, you need to transfer it to the door leaf. After that, a pen drill is installed in the drill, but of a larger diameter. Drilling a hole for the handles is necessary on both sides. Otherwise, there is a high probability of damage to the decorative coating of the door leaf. After the tip of the drill appears with reverse side door, you should stop drilling and continue it already in opposite direction. In the same way, preparation is carried out for the secret of the castle, if it is present in its design.

After that, you can assemble and install the locking system and handles. The lock is inserted into the end of the door leaf and fixed with screws. Then it is inserted and fixed with one screw from the side of the decorative strip of the lock. Now it remains only to install the mounting square in the hole and put the door handles on it, which are fixed with the screws or ties that come with the lock.

This is how the answer to the question of how to put the lock was obtained. If the work is done carefully and carefully, then the result of installing the locking mechanism on the door will meet all expectations.
