It is believed that the castle "in the lobby tail" has sea roots, the tail of vessels with a wooden case was performed in the lobby tail. Such a compound turned out to be the most resistant to the wetting of wood and multidirectional loads caused by the excitement of the sea. The main advantage of the technology has become a reliable docking of wooden parts without the use of additional fasteners, the reliability of the attachment provides the lock of the original trapezoid form. As part of the tool of ship carpenters had a special saw with the name "Lastochkin Tail".
Traditionally, in Russia, the crowns of the cut were laid "in the bowl", such a clutch was cut off with an ax. With the advent of a good joinery tool, the log house began to lay "in the paw", the connection had a rectangular spike. The further improvement of this castle was the use of a schip "Lastochkin Tail" with a trapezoid profile.
The lobby technology tail for fastening the bar has become the main in industrial house-building, sizes and features of the compound are determined by GOST 30974-2002. The introduction of the standard created favorable conditions for the development of low-rise house-building, domestic wooden houses Industrial production in quality is not inferior to Finnish samples.
The standard sets of carpentry connections to the lobby tail:
A distinctive feature of these types of fastening is the design of a spike-groove, which has a trapezoidal form with a direct base.
The fastener of the bar "in the paw" is the easiest way to build a cut, a reliable grip provides a spike of the trapezoidal shape, which is cut into the end part of each row of the crown. Properly made and assembled castle reliably fixes the crowns of the cut in all planes. The fastening is universal, used to build a car from a bar and rounded logs, the connection "in the paw" is used to be used in the construction under the shrinkage.
The design distinguishes the absence of ends, protruding for the corners of the structure, such a castle is called a "pure angle". A spike in such a design is a carrier element and carries the main load. To build a cut in a "pure angle", it is recommended to use the timing of maximum sizes, with a side of at least 250 mm.
Run a fastener of a swallow tail with your own hands is quite difficult to avoid errors using a full-size spike pattern of a swallow tail for a bar, the sample can be cut out of fissure or tight paper. The pattern is applied to the end and outlines, the boundaries of the propelobs are planned with the help of a hammer and a chisel. Duties make manual circular saw. The easiest way to make inclined feedback after 10-15 mm, crawl over the ax and resubmission the chisel.
The advantage of technology is the ability to work with a lumber of natural humidity, in this case the spikes are made with a switch of 5-7%. The allowance will result in the formation of gaps between the crowns, which in the process of shrinkage is eliminated by naturally.
Disadvantages and features of the connection to the lobby tail:
On the technology of the log house in the lobby tail build country houses Economy class, baths and household buildings, such a construction is low-cost and accessible to a massive developer.
This method in construction practice allows you to fully utilize the advantages of trapezoid attachment, a feature is a secret T-shaped groove-spike connection. The size of the spike does not exceed halfbrus and completely recessed into the body of the bar. The angle of the house collected by such technology was called the "Warm Corner". The lock provides a reliable clutch into a crown without through slots, when processing the construction sealant creates a fully sealed space. The bar is increasing in the same way if its length is less than the length of the wall.
Profile picking is performed according to the drawing using a circular and training saw. The rectangular billet under the thorn and groove is cut with a circular, the specified form is given by a special hand saw. For cutting grooves, you can use a manual milling mill, workplace Easy to equip yourself.
Advantages of fastening technology Deaf "Frying":
The main feature is the increased demand for wood moisture - the sawn timber must have moisture in no more than 20%. Technology is widely used by manufacturers finished houses "Full construction".
This method is used in the construction inland partitions From the bar, laying lag for the floor and ceiling floors. The groove is pumped on the entire width of the bar. The lock reminds the connection "in the paw" in the T-shaped version and ensures fixation of the structure in the horizontal plane. This fastening is simple, can be cut with a circular saw and processed by the chisel.
A simplified version of the castle of frying is a profile in the form of a rectangular trapezion, fasteners are called semi-dem. Such a fastening is designed for more wet wood and is popular with individual developers.
Further development of the connection scheme into the lobby tail, received in a key bond. The knap in the form of a butterfly formed by two trapezoidal shapes is made of solid wood. The groove is cut on modern milling machines. The sponge compound in the lobby tail fastening sizes are minimized, but such a design provides reliable fastening wooden structures Any complexity, allows you to put the production of products from a tree to flow.
Peculiar features:
Bonding with a key applied by manufacturers of finished wooden houses From an expensive glued bar and allows you to implement the most complex projects of houses.
Connections of a bar in a lobby tail in house-building is a reliable way to fasten wooden parts. With the advent of a modern joinery tool, this technology has become available for mass application. Such a fastening is widely used in the design of the interior and the manufacture of small architectural forms. In miniature performance, such fasteners are used in the production of furniture.
The detachable fastening of the details by the "Lastochka Tail" method is made by setting in the groove on one side of the billet of the trapezoid spike, discharged in the edges of another element. The type of component of the parts is used in many designs that require the creation of a rigid in-point frame: short arms, furniture manufacturing, engineering, wooden capital construction.
After the drawing is compiled, the sizes of the "swallow tail" are selected individually. The wizard starts fulfilling the preparatory operations, in the course of which the village and Salazki take part. The material used in the process of solving the problem with loaded nodes may be steel, cast iron, bronze. In other cases, the types of compounds can be performed from light non-ferrous metals and plastic mass. The surface of the product is processed by the profile milling with a browser with a scraper or disk for polishing.
Before making a "swallow tail" with your own hands, you should create a drawing, the dimensions of which must withstand permissible operational loads. When performing propyl, it is necessary to correctly select the angle of inclination of the sides of the trapezoid, the standard value of which is 45 0, 55 0 and 60 0. The connection to the selected method is used in the system:
TO positive properties Technologies include high construction strength. The use of the method allows you to fasten the elements without nails, screws, screws and chops.
Wooden spikes and fastening grooves must have an identical shape and connect to a dense hermetic node. The compound "Lastochka Tail", the drawing of which is designed for different products, helps to form a T-shaped and angular bonding of boards, bars or logs without bare in places of installation of internal partitions. Wood assembly technology allows you to use for interior partitions construction material smaller diameter. If you need to protect against wind and drafts, angular articulations of construction capital constructions Sealing jute fibers.
A classic example of using the connection of the elements is drawer Furniture headset. Electrical carpentry equipment used in the device of the spike groove system for a manual milling maker allows you to interweathe the thickening elements using the natural strength resistance to the force applied to the front of the product when extending.
The compound, the drawing of which is compiled for each item individually, can be performed in different ways.
Most of the masters working in furniture manufacturing and house-building are preferred by the method of a cross-cutting joint connection due to the decorativeness of the recurring pattern. Preparation of elements is carried out on the milling machine with a special device.
Preparation of material for connecting the spike groove with your own hands on the template is carried out after the "tailings" marking on the flight, a pencil or marker on the sides and faces of the part with the nests or partitions. The dimensions and the number of elements depends on the type of material, the width of the board and the method of spikes. For giving decorative view The spike connection lines must have the same dimensions, located at the same distance from each other.
Prior to the start of work on the machine, the material is equipped with marking of the preparation of 6 mm from the edges. The remaining part of the board must be divided into an even number of spikes, measure 3 mm from each side of the marks, carry out a marking line perpendicular to the end. With the help of the stencil or low, the contours of the ships shape for joints under the "Lastochka Tail".
To form the connecting elements, the box blank is installed in the vice in such a way that one side of the spikes is vertically. On the side faces of each spike, nozzles are made, not reaching the line of cloaks, the blank is reinstalled, and other side faces are processed. After that, the part is fixed horizontally, cut off the side waste in the level of the blowers. Excess wood between spikes must be removed by an openwork saw.
For accurate marking of the landing socket, the workpiece is installed on the joine table in the vice with a vertical position, the eck of the board is rubbed with chalk to obtain a print on the parts with already cut spikes. With the help of a special device, the edges are aligned, the line of the side of the side of the side of the spikes and the end of the workpieces with the sockets.
After finishing preparatory work you can proceed to the formation of the groove in the corners of the workpiece Next to the line of cushions in accordance with the thickening markup. Propil, for which the milling plate is used for a manual milling mill, should be made in the waste part of the board so that the groove is placed parallel to the markup line. Surplus wood between partitions of the socket is removed by an openwork saw, hesitating the chisel or chisel with a beveled edge. The movement of the tool must be directed from the edges to the center.
For the production of products, the connection of parts of which is carried out by the method of "swallow tail", almost all types of wood, plywood, plastic are used. A feature of the method is unsolved technology using fasteners (joinery glue). Checking accuracy and fitting parts is carried out after:
The adhesive substance is applied to the contacting parties of two parts of the tree. For a dense connection of the structural parts, a hammer and a wooden gasket that protects the product from random damage is used.
After closing the connection site throughout the line, it is necessary to remove the excess glue, the product is sent to drying, followed by a filling of Fugansky in the direction from the edge to the middle.
Standard bonding angles should not be sharp or stupid. The large bias of the milling propyl contributes to the formation of short fibers in the angular part. The insufficient tilt of the groove reduces the strength of the connection of the elements. To solve the problem, experts recommend using a bevel markup, templates or stencils. For wood solid wood need to choose optimal bias Propil, which should be 1/8, for the soft tree of the tree, the milling of the slope is made on the 1/6 part.
Carefully completed groove "swallow tail" can serve as an additional decoration for household and office furniture. Options for designing furniture designs allow you to emphasize the beauty of wood and evaluate the skill of the specialist. The selected product assembly type corresponds to the indicators of standard design proportions.
A feature of the "swallow tail" is the ability to overturn in the parenthese log or timber of the trapezium at the angular fastening of the parts. IN wooden construction The method of connecting the bars in the "indigenous spike" method is often used, when two elements are spliced \u200b\u200bwith a rectangular spike and a groove of a similar shape. Drinking parts for the connection is carried out by cutter according to drawings, diagrams and sizes.
The reliability and aesthetics of complex structures from the tree largely depends on right choice Method of connecting it component parts. This is especially true for frameworks carrying structures where security parameters go to the fore.
A high-quality connection of wooden parts is a pledge of durability, the basis of an attractive type of product, an indicator of skill and professionalism of a carpenter and a joiner.
In general, there are a huge amount of compounds of wooden blanks, so you can only tell about some of them most common.
One of the most simple ways Instructing a wooden part (timber, log, board), increase its width is the end connection. There are several options for its implementation. Often apply a simple and functional method in half thickness (in trustess). Depending on the intended load on the part, the slice can be even or oblique. In some cases, the joint is strengthened with curly cuts - locks. This type of compound prevents stretching, twisting, bending. So the timber is spliced \u200b\u200bwith the purpose of elongation.
Creating bulk frames or wooden frames requires reliable compounds under various corners. In this case, rationally use the connection of the type of spike-groove or spike-eye. The nodes at the place of the joint of the parts withstand the load of the displacement, bending and compression. If the designs are needed high resistance to the gap, cutouts make a trapezoidal form.
Additional links of framework products that give rigidity are implemented using T-shaped or cross-shaped connections. The main load on the joints is compression, offset and gap. IN special cases The design is additionally enhanced by metal corners, screws or nails.
To connect the boards between themselves in box designs at right angles, it is convenient to use a special box groove. As it is clear from the title, this method is often used to create bulk structures, including furniture boxes. A qualitatively made drawbuch looks monolithically, has an attractive look and withstand impressive loads. While creating wooden furniture Often use the connection on the wanks, impudent and domino (when the groove has an oblong shape, unlike a round wad).
The simplest and one of the most reliable is the connection of the spike groove. It is widely used in carpentry business. This method is collected into a single whole wooden details of window frames, make the most different parts of cabinet furniture, plywood sheets. The essence of this method is that at the end of one connected part, spikes make, which is inserted into the groove of another part and is fixed in it.
To work it is convenient to use a special lamella milling mill, for the absence of such you can do with a simple hand tool. It will take:
First place the workpiece. The parameters of the spike and groove depends on the parameters of the wooden parts and the configuration of the product, it is not less to take into account several general recommendations.
Important! Thickness of the spike should be about a third of the parts thickness, the width is 70-80% width, the length should be equal to the thickness of the combined billet.
Parameters The groove should also correspond to these criteria. In any case, it is important to ensure that the sizes of the spike and groove coincide. Details should be easily connected, without pressure, but not falling under their own weight. There should be no backlash, cracks and skewers.
The first to cut the grooves, such a sequence is caused by the fact that the spike is much easier to customize under the groove than the opposite. With the help of the saws, the cuts are made, excess wood is removed with a drill, the bottom of the groove and walls are aligned with the eyes.
In most cases, for fixation of parts, just one joinery glue is enough, screws or nails will help to ensure maximum strength.
Quite often in joinery use various options The junctions in the trip (simple or straight lock). This type of assembly of wooden structures is characterized by ease of manufacture and high reliability. The following varieties are distinguished:
The first two methods are used to connect parts that are crossed at right angles. The lobby tail is especially popular in which the shape of the cutout is a trapezium and the sides are not at the right angle. The lock of the lock is slightly expanding from the end, providing more reliable fixation. It should be noted that the thickening connection can also be called a swallow tail if the spikes are cut in the form of a trapezium.
The second and third methods form a finished angle. Splicing applied if necessary, increase the length of the workpiece.
One of the easiest is the transverse connection. It is characterized by simplicity of manufacture, to master it with the wisdoms may even be a novice carpenter. The work is performed in the following order:
Now you can dock wooden blanks. The compound must be dense, without hollows and gaps. If the product is in detrimental, the joints are wedged with carbon black, the design is additionally enhanced by screws.
One of best ways Creating angles of various volumetric products is a joint on the USS. It allows you to create a monolithic design, hide the fiber of the end, thereby ensuring an attractive look. This method is suitable for a wide variety of products, but most often used for the manufacture of frames and parts of cabinet furniture.
To create a compound in each of the wooden parts, peeled corners at an angle equal to half angle, under which the billets are found. Most often, this corner is direct, therefore, the pressure is performed under 45 degrees, nevertheless an angle may vary widely. Works are performed according to the following algorithm.
First place the details. It is important not to forget that the markup is performed along the long side, otherwise you can not guess with dimensions.
On the edges that will be connected, conducted a line at the required angle. The combined coal markup is transferred to each side of the workpiece. Then they perform the cut, for which it is better to use an electric face saw, but you can work with a hand tool. Working with a hacksaw, it is important to control the corner of the cut, it will be useful to use Bru as a guide.
Finished parts apply each other by checking the accuracy of fit. Unemption will have to smooth out hand-held Rubankom, bring the angle with the help of grinding skins. A joinery glue is applied on both surfaces, and with clamps, the product is fixed. Additional strength can be achieved with carnations. Working with a hammer, it is important to control the strength of the blow so that the blanks do not move.
Particularly responsible compounds are enhanced by bars that are pasted into internal corner. A joke that will not be visible, you can additionally strengthen with a metal coal.
As a result of high-quality work, perfect seams will be performed. If a small gap was formed, then it can be hidden by placing the adjacent wood fibers using a smooth cylindrical surface. For this, the rod of the ordinary screwdriver is suitable.
Corner and brazers (example: T-shaped connection window Rama) The intersection is convenient to perform a spike-crest method in the eye. In this case, the eye is made in the end of the vertical part, the spookies under the thorn - in its horizontal component.
Work begins with the markup of the eye. The thickness of the workpiece is divided into three. A thin knuckling makes the cuts to a depth equal to the width of another workpiece. With the help of the chisels remove excess wood, the walls of the eyes align the sandpaper.
Place the second workpiece. Ship width should be equal to the width of the first billet, the thickness is equal to the thickness of the spike. The propuls are performed by manual hacksaw, carefully control the depth and angle of inclination. Excessively remove the chisel.
Final finishing in thickness is performed using sandpaper. Details must be connected with a lightweight effort and do not fall under their own weight.
A more complex connection is the method of spike in the nest. It requires greater skills, but is distinguished by much higher reliability and durability. The scope of use is the same as in the previous case, namely, T-shaped joints. The difference of this method lies in the fact that the spike is made in the end of the vertical part, the socket is cut in the body horizontal.
This is one of the most common furniture connections. There are a connection with a cross-cutting spike and deaf. The difference is that in the first case the through nest is cut, in the second, the slot is done on a certain depth.
Unprecedented joinery art heights reached Japanese masters. Using traditional techniques, combining different types compounds, they create accurate and reliable joints without applying nails and other fasteners. Docking various wooden parts is performed solely due to the strength of friction.
The basis of the reliability of these compounds is the exact cut. The perfectly fitted lines of locks on both mating details allow you to create a connection with impeccable accuracy. Complex configurations of locks require greater experience, knowledge and skills to own a tool, but if desired, everything can be learned.
High-quality wood is expensive, buy a good board with the necessary parameters is not always possible, but not always and necessary. To make, for example, a worktop, it is not necessary to look at the table with a width in the table, having a joinery skills, you can create an ideal wooden canvas with the necessary parameters.
Highlight options. Widespread board with spike and groove, the so-called lining. It allows you to create smooth wooden surfaces of a large area. It is often used simplified version - a board with a quot of joint.
The easiest way that does not require additional elements. Side faces of boards fellow, it is better to do it in pairs, clamping both neighboring boards in a vice and simultaneously treating them. Such processing will create an accurate surface on which the irregularities of one board will be compensated by the irregularities of the other. Both boards are missing with glue and fix it until its full pouring.
Lengthen (increasing) a board that is part carrier design You can in several ways. The easiest and most reliable is the connection in drapery with the subsequent lining on the place of connection of reinforcing slats. Uncritical sites can be enhanced by plywood.
The same method is used and for the articulation of boards at various angles. Exactly completed parts of the articulated parts allow you to do without reinforcing linings, it is enough to fasten the boards at the junction point of screws.
Cutting without a residue means that laid logs will form a smooth angle, their ends will not be outside the structure, its separate variety is a warm angle. The cutting with the residue, in turn, means that in the corners of the building, weaveting from protruding ends will be formed. The second method is more costly in terms of the amount of material, but the building is better preserved heat and more stable.
Exist various methods Connections of wood parts, the ability to determine the optimal work for one or another type of work will significantly diversify the range of products that the master can be made. The correctly selected method will provide an attractive appearance Product and ensures the reliability of the bulk design.
Now you are not limited to the width of your milling template.
Fixture for milling open connections "Lastochka Tail" is usually used to work with a width of no more than 305 mm wide. But this does not mean that you cannot make such connections on the shields of any width. Just free the pattern-comb from the base that limits the width of the blanks, and secure directly on the shield. This is how it is done.
You will need two mills at once: one for the cowle cutter "Swallow tail" and one for a straight cutter that generates spikes. This allows you to do without replacing cutters and depth settings. Still prepare a couple of trial blanks, the width and thickness of which exactly corresponds to the details of your project. You need to make "swallow tails" on one board (blackboard with "tails") and spikes - on another (spiked board).
Remove the combing pattern from the device and free it from all the stops and brackets. Make from cropping two slots 76 mm wide along the length of the template. Their thickness should be such that they can be 13 mm into cuts on both edges of the template. Attach one spacer for screws to the bottom side of the template, and set aside another. Swipe the basic line on the inside of the board with "tails". To do this, put the board with spikes on the end, aligning it with the end and the edges of the board with "tails". Marking knife Mark the thickness of the blackboard with spikes on the chalkboard with "tails".
Clamps secure trial blanks on opposite sides of the spacer, placing them with internal parties to the outside and tightly pressed to the underside (Photo a).Turn this assembly template up, install the second spacer between the workpieces, and then fix it all in vice or on the front side of the workbench so that the board with "tails" has been addressed to you (Photo B).
The edge of the boards with "tails" should be located exactly in the center of the cutout. Use the salt to level the edges of both billets so that they match the finished connection.
Attach the workpiece with the template to the thick bruster fixed by the clamps on the workbench. The sandpaper on the front face of the bar prevents the displacement of the parts.
Now let's mark the sections of the material that you are going to remove. For thickening connections with a variable step (such as in the project "bed stalls") do not cut the cutter through all comb cuts. For example, for the walls of a variety of 400 mm wide, we marked the first two cuts, then they missed one and put the label under the fourth cut (Photo C).After skipping two more cutouts, marked the seventh, then they missed three and marked the eleventh cutout.
Finally, adjust on each milling milling cutters by 0.5-0.8 mm below the base line marked on the gloss with "tails" (Photo C).
Make a removable material between "tails". Then adjust the departure of both cutters so that the spikes and "tails" spoke slightly above the shield surface. Collect them flush after assembly.
Select mills only in comb cuts, located above the marks. Frewell does not rush to reduce chips, but not too slowly so that nozzles do not appear.
First, the tail "Tails" (PhotoD.). Then take another milling mill and make a straight milling passage in each cutting ridges for spikes. It is necessary to work carefully, since when milling spikes it is especially important that the sole of the milling is tightly adjacent to the template. The slope of the cutter leads to irregularities at the edges of the spikes.
Loosen the top clamps and move the template so that the formed spikes are located in the middle of the cuts (Photo E).(Perhaps, for this, you will have to apply the Cyanka to a slightly tapping it on the spacer.) Mark all the spikes located opposite the "tailings". Tighten the clamps again and make sure that the blanks are tightly pressed against the template, and their edges are aligned. Then remove the milling flares. Depending on the template used, a small burr can remain on the workpiece in the form of a thin shavings, which can be broken, and you can again move the ridge again to clean the cutter between the remaining spikes.
Mark removable spikes, putting crossings on those located opposite "tails". Leave only the spikes located opposite the faces.
Lifting the template and fixing the workpiece again, mark the remaining "tails".
After stripping thorns again, loosen the top clamp and move the template so that the untouched edge of the boards with the "tails" was in the middle of the cutting (PhotoF.). Put the labels to complete the formation of "tailings". (Only one eyelet remains on our shields.) Then repeat the entire process to make the connection completely.
Try to assemble the connection. Light assembly and perfect density can be achieved by moving the pattern-comb forward or back relative to the spacer. If the connection is too dense, slide the template towards the "tailings". If too free, slide it towards spikes. Dispise the edges of your trial blanks and make the following attempt until you achieve the optimal result.
When it is possible to safely connect trial blanks, knock off the connections on the details of the project. Remember that at each end of the comb, the opposite corners of the box are processed. When the board with "tails" is drawn to you, the connections for the front left and rear right angles must begin from the left end of the template. Connections for the front right and rear left corners are made at the right end of the template. Then the "tails" will be located on the front and rear walls of the lady. Before proceeding with the milling of the project details, temporarily secure them with clamps and mark each item and every angle so as not to confuse.
Swallow tail, turbid spike compound (grooves of trapezoidal form) used in mechanical engineering and joinery for reliable fastening of parts with each other. In this material, consider the manufacture of fixtures of facilitating the production of grooves in the tree using a manual millingrer.
The machine itself is a very ancient invention of humanity, describing the principles of milling appeared in the 16th century, and the prototype of the machine was the invention of Leonardo da Vinci, which offered to rotate the round file to increase the processing of the product, which can be considered the first counterpart.
And the American inventor of Eli Whitney over the years of life from 1765 to 1825 brought to mind all the scattered attempts to create a full-fledged machine, for which it is considered to be the creator of the first milling machineAlthough this approval agree not all scientists.
And since the machine has such ancient roots, then the devices to the manufacture of various parts a great set, describe them all in the world this material It is not possible, and therefore consider only some of them, in my opinion, the most important and useful.
factory plate for the manufacture of spike groove compound
Used with a milling cutter of the corresponding grooves and spikes, it is installed in vice, and the part is pressed the clamp to the device. As a rule, sold in stores.
appearance of the connection
Put the upper part - a tabletop of 18 mm plywood with a length of 40 cm. And sufficient width to treat the most thick workpiece that you plan to connect spike.
Cut two brus 5x10 cm., Scuffing them the same length as the top. Broi will continue to play the role of clips and centering it relative to the groove in the tabletop. To prepare the top, spend the line in its center, then ellipped the gamestone from one end.
sketchy image of equipment
note
Reception should be the same width as a copy ring that you will use with your cutter. Reception should be long enough to fit the length of the longest groove that you are going to cut.
Then throw two perpendicular central lines of the adjusting groove. Finally, drill the viewing hole between these two grooves. To collect the whole design, screw the bolts in the sponge and fasten the top to the bars with lamb nuts with washers.
To use our equipment, draw the groove on the workpiece and mark on it a central line. Loosen the lambs and install the blanks between the bars so that the central line connects to the vertex line of the adjustment, check that the edge of the workpiece is opposite the edge of the vertex.
Hold the lamb. Align the milling mill at one end of the groove drawing, then mark the auxiliary lines on the top surface of the table along the edge of the milling base.
How to work properly with a spike groove
Repeat it again to mark the line of another end. Sweep the groove, bottom of the cut from the alignment of the Pillar base on the first auxiliary line, and stop the milling when the plate reaches the second auxiliary line.
Spike Production Product
Made of wood and plywood conductor, shown above, allows you to cut rectangular spikes with two blowers. The processed object is the front surface from the bottom under the conductor, while the milling mill moves along the stop from above, removing unnecessary for two passages.
The product consists of two parallel basic bars, a stopper and stop - everything is made of the tree of the same thickness as the part, in this case, from the 25x75mm bars, as well as the upper surface and support made from 18mm plywood.
Basic bars should be approximately 400 mm long; Cut from plywood the upper surface approximately 200 per 250 mm and brought it to the bars as shown in the figure. Refer to the stopper at the ends of the basic bars with support. Install the stop approximately 25 mm from the end of the upper surface.
cut the spike using the device
Slide the holes under all screw heads and make sure that all the corners are rectangular. Drill the viewing hole in the upper surface to accurately put the workpiece exactly on the markup.
