How to fold a ribbon saw with a ring. Annealing

How to turn the strip saw into the ring

To saw I sawed the material evenly and the tape was not pushed, on a narrow beam along the stupid saw end, guides are installed. A common version of the device is three bearings located on the beam, on one of which lies the canvas with a flat side, the other two support it from the sides. Sometimes on the sides instead of bearings are placed by wood limiters.

The guides are aligned at the reference point, so that there is no vertical deviation at the opposite end, for convenience the position of the beam is noted during the canvas bred.

Wood vertical tape saw

The machines for sawing a vertical tree tree differ in that the canvas that contacts with the cut surface is located vertically. Highway strip saw On wood of this type, it can be used in small wood processing workshops, as well as in home workshops for household needs. Such a tool easily copes with materials of a variety of width and can work in any trajectory. The sizes of tape saw on wood of this type may differ. When choosing a ribbon vertical saw, it is necessary to remember the following characteristics:

  • Moving speed of the canvas;
  • The length of the canvas;
  • Number of speeds;
  • The ability to regulate the angle of the table;
  • The depth drank;
  • The weight of the machine.

Basic materials:

A rectangular frame of the machine is welded from the profile pipe. A bed from the same pipe is welded into it at right angles. All sizes are selected individually, starting from the length of the selected strip canvas. The bed is welded to the crossbar inside the sole. Its racks must be shifted as in the photo. An engine will be installed in the lower offset, and in the upper table.

Next, you need to make a guide for fastening the upper pulley of the tape drive. It consists of a frame from a narrow profile and two segments of a large pipe. A square is welded to them to form skids to slip a frame. The pipe with runners are welded on top of the bed so that the frame is inserted between them.

A hole is made in the frame itself, and the spill M12 is welded into it. Then a fork for installing a bicycle disk is welded to it.

The springs and a small segment of the profile pipe with the hole are put on the hairpin, then the nut is wound. The frame is inserted into the runners, and the pipe on the hairpin is welded to the guides. You can weld the handles to the stiletto nut to rotate it without the key when adjusting the tension of the canvas.

A disk is inserted into the fork, a canvas is thrown on it and a measurement is made to determine the height of the lower pulley placement. A segment of the pipe with a hole for the disk axis is welded to the label to the margin. Next, a M-shaped blank is welded to increase the rigidity of the mounting of the lower pulley of the tape drive.

The discs are removed, and rubber stripes cut out of the chamber are glued into several layers. On the tubercles from knitting needles, the rubber is drilled with a small crown, and another strip is glued on top. Then the rings cut out of their native chamber are pulled on top of the disks.

On the axis of the lower disk to the asterisk, the pulley is welded under the belt. After that, the discs are installed in place, and a saw blade is pulled on them.

The base is welded to the machine bed, and the engine is screwed on it. Then the belt is pulled between it and the pulley on the disk.

So that the saw blade is not pushed back during sawing, it is necessary to make restrictive videos from above and below. In their quality, you can use bearings. For this, a G-shaped bracket is made of sheet steel. 3 bearings on the shoulders from the square are installed on it. 2 of them will move to each other to hold the canvas on the sides, and one is attached relative to them at right angles to maintain it from the ribs.

How to turn the canvas of a strip saw

Clamping of a strip saw is a process that you should prepare for, since otherwise you can cause physical harm to yourself: cut or scratch. Often, the newcomers often deteriorate, because sharp teeth pierce it.

Fundamental rules

The main rule when turning the strip saw. There should be reliable gloves on the hands. They will help in controlling the process and protect their hands from damage. It is also worth using clothes with long sleeves, trousers and boots.

fold, ribbon, ring, annealing

A person will not have to be protected if you remember the rule: the saw should be away from the head. Even if she has already been turned. In this case, the edge always goes down so as not to accidentally cut.

To learn how to turn the saw, you will need training and the development of the algorithm proposed later. If there are concerns for the integrity of the tool, then it is better to try your strength on unnecessary due to old age or integrity of teeth instance.

The algorithm of actions

Step.By.Step instructions for folding the strip saw:

  • Turn your hand with your elbow to you and pull it down. In this position, take the saw on one side, and on the other, press it to the floor with your foot.
  • Turn your palm up, holding the saw at the top point, do not let go of your legs. Lower your hand a little so that the tape is 3 circles.
  • Press the rings to the floor.
  • Change the diameter of the resulting rings so that they become round and the same. This may not work right away, so you have to make a few attempts.
  • Use the wire to fix the tape in three places with an equal distance between them. Make sure the reliability of the fixing element.

For the last point, it is best to use a wire folded in half. Before use, it is worth evaluating it for damage.

The main thing is not in a hurry. Try to do everything right to get used to the algorithm. The speed will increase over time.

Homemade strip saw

Ribbon saws are an obligatory tool in each workshop. Ribbon saws are also used on sawmill, strip and cutting saws.

The quality and reliability of the tape provide an excellent opportunity for its reuse and allow you to use it in all areas of construction.

Band-saw This is a cutting tool used for strip saws. In its design, the strip saw has the shape of a flexible steel tape, tightly fixed, with several teeth on one edge.

The belt is installed on two pulleys that rotate the tape saw electric motor.

Using a strip saw, you can make both straight and shaped cuts. That is why the scope of its use is very diverse and is not limited to construction work and furniture production.

How to do something yourself, with your own hands-a site of a home master

An excellent tool for masters and needlework and everything for the garden, at home and cottage literally for nothing. See for yourself. There are reviews.

The easiest answer is to get a maximum from your workpiece. For example, instead of stricting a board with a thickness of 25 mm up to 10 mm, its dissolution will allow you to get two of the same size from one board. As an additional advantage, each of these boards will have almost the same fiber pattern, which will allow them to be launched on the cladding of furniture (photo on the right). And if you dissolve 2 5. A millimeter board made of woodwood on sheets of veneer with a thickness of 3 mm, this will allow you to get even more.

It is not always possible to predict how symmetrical in the drawing will be sawn panels. In principle, any drawing of wood fibers has a potential for creating a beautiful pattern, but the choice of a workpiece with a particularly interesting pattern often brings the best results. See what was hidden inside the plainboard, which I used to check the adjustment of the strip saw.

For the first time I saw a closet with a symmetrical pattern on the doors in the museum, at an exhibition of furniture of the XVII.XVIII centuries. Having examined these almost identical panels with a mirror pattern of fibers, I was struck by them. In those days, in my small basement workshop there was an old ribbon saw Craftsman. Its canvas of the type “Unified size for all work” made it possible to make acceptable curved cuts, but it was not at all suitable for dissolving lumber along the fibers accurately, which I planned to do now. And, frankly, for accurate and stable work, that saw needed not only in the new canvas. Subsequently, I learned a lot of lessons on how to handle any strip saw. For its literacy, first of all, you need to install the table strictly perpendicular to the saw canvas, get the maximum return from the guides and make sure of the right direction of the cut.

Tool for home and garden, needlework, etc. The are very low

Take a canvas with a more aggressive car. A blade with three teeth per inch and large recesses between them removes sawdust better, which can cause bending and twisting the cutting canvas. Keep the workpiece tightly pressed to the guide and to the table. A special pusher transfers the necessary squeezing effort to the guide and allows the hands to be at a safe distance from the canvas when it was dissolved.

After the strip saw is well tuned, you need to pay special attention to the saw tape. Slinging wide boards requires a canvas, which evenly passes throughout the thickness of the workpiece, while removing a large number of sawdust. The wider the blade, the more it drank, so try to use the widest canvases that are suitable for your saw.

Install the square at a distance of 6 mm from the saw blade (to put it, you may need to raise the protective casing) and press your finger to the middle of the blade. From the average pressure of pressure, the blade should touch the square. In this photo, the saw canvas is too much shifted back on the upper drive wheel: therefore, the cut deviates to the guide. If the canvas is too much shifted to the front edge of the wheel, this leads to the opposite result.

Most tape saws work at least with 12 mm canvases, and many with even wider. As a rule, a wide canvas with three teeth per inch length (3 tpi) offers an ideal combination of aggressive, but smooth sawing with an active removal of sawdust, which is required when the tree was allowed. Finally, let’s talk about the guides. The cutting for the saw should exceed the height of the guide by no more than twice. So, for example, a 100-mm guide is suitable for racing boards with a width of 200 mm. If you need a lot of height, use home.Made additional guides.

How to turn and turn a strip saw

Cutting and turning the strip saw must be performed carefully and carefully. We offer step.By.Step instructions on how to do it right and safe. Remember that when handling a strip saw, you always need to wear protective gloves and glasses, and in addition, you need to be at a safe distance from others, so as not to accidentally injure them.

One. Take a saw, folded in three loops, in the right hand.

Find a loop that forms the figure eight, and pull it down with your left hand.

The two upper loops at the same time form a cross.

That loop that ended up at the very top, keep with your right hand. Another loop. Left.

Keep the saw in front of you and slowly spread your hands, while opening the wrists outward and down.

One. Take the saw ring with two hands so that the teeth are directed in your direction. Squeeze the saw ring slightly.

Shake the saw so that the upper part of its ring bent down.

Give your hands, slightly turning the wrists inward so that crossing forms on the descending bend of the saw.

Saw forms three loops. Take the lower loop with your left hand and raise it to fold all three loops together.

The saw is folded. With the help of wire, bandage the folded saw so that it does not turn around suddenly like a spring.

Quality control

With careless welding, the following defects are possible:

  • The displacement of the planes of the canvas relative to each other occurs due to a large stroke or small current;
  • Splashes of molten metal on the surface of the tape occur at high current;
  • Non.Brewing occurs with low effort and small course of a rolling clamp or insufficient current.

In a qualitatively welded canvas, the suture roller protrudes above the plane of at least 1.5 mm. The check carries out the flexion of the tape with a radius of 20-25 cm. If a circle is obtained, and cracks do not form on the seam, there is nothing to worry about. If the canvas bends in the form of the letter V. The metal was overshadowed by annealing. The appearance of cracks indicates hasty cooling.

How to make a carriage for cutting circles on a strip saw without a hole in the center

Materials necessary for homemade.- leaf plywood, wooden beam, nagel-Slider for T-TRAC.Double-sided tape, oil-Vosk- Titebond II carpentry glue, two.Component second glue, epoxy resin, sandpaper.

Production process. So, the table of the strip saw is often equipped with the so-called T-shaped groove, which serves to install various devices. He will serve the guide for the future carriage.

For such grooves, you can apply a ready.Made slider, or make it the simplest analogue on your own.

This will do the master. First, the dimensions are measured-the width and height of the T-TRAC.

The runner itself is cut out of a wooden beam (it should be from solid varieties of wood) on a circular saw.

Further, the rail with a rectangular cross section turns into a T-shaped profile on the milling table. This is a homemade milling table with a plate installed on it with interchangeable rings.

The finished specimen of the runner sits in the T-tracker not too tightly, and at the same time does not hang out, all its sides are smoothly cleaned.

Next, a rectangular workpiece for the base is cut out of the plywood sheet on the circular saw. The thickness of the plywood should be 20 mm or more. This is necessary to form a groove in it.

The finished scrap is glued to the lower part of the base at a distance of 22 cm from the edge (slightly larger than the distance from the canvas to T-T-track). Two types of glue are used here: superclles at the edges and in the center, wood glue on the remaining surfaces of the runner. Superclles plays the role of a fast fixator, while carpentry glue provides the durability of the connection.

The foundation plate is found in a Poloz in a Trek, and the first incision is carried out. It passes parallel to T-Treku.

Then the author marks the line on which the groove of the “Lastochkin tail” form will pass. The latter will be located perpendicular to the plane of the canvas of the strip saw.

An important point is that the center of the groove is clearly flush with the cutting edge (teeth) of the canvas. Otherwise, there will be problems with centering the blade, and it may be distorted.

PAZ milling is carried out by a manual milling mill along the guide. In this case, the cutter of the gallway is used.

This form of the groove was chosen by the author as the simplest, because there will be no special loads on it. In another case, I would have to bother with cutting a T-shaped groove.

Now a disk is made from the cut of wooden bacets, from which the head of the clamping screw will be made. It will be a kind of center for rotation of the processed parts.

In the center of the trimming of the round, a through hole for the screw is drilled. With the help of Zenkovka, a deepening is formed under the screw head.

A screw is inserted into the hole. A nut is put into the groove in the carriage, and the screw is screwed into it. It turns out the semblance of a clamping mechanism.

Welding and soldering tape saw: how to do everything right with your own hands?

The woodworking industry is widely used by saws, the main feature of which is a continuous cutting surface. It is a ring from a tape with metal teeth.

Welding tape saws underlies their manufacture, since they are obtained by connecting a pre.Prepared tape into the ring. This process is also used in their repair. This article will tell about the main features of welding of such devices.

Whole and at once

If you carefully read how the work is going in the first way, you should have understood how really it is really difficult to sharpen the saw high.Quality.

There are constant conversations that it is impossible to quickly and well saw with narrow tape saws. The saws are torn quickly. For proper preparation, it is almost impossible to find a sharpener. Pilomaterial at the output is obtained with a large wave, which negates all the advantages of thin cut.

So, in order to radically solve all these problems at once, Wood-Mizer was offered a way to not consistent tagging of each tooth of the strip saw, and at once the entire tooth profile only one entry into it of a special specialized disk.

In this way, three main problems are solved at once:

  • No need to look for a highly qualified sharpener. On such a machine, almost any person can sharpen a saw on one pass with factory quality. He only needs to bring the disc to the saw. The rest of the machine will do it itself, which makes it possible to maximize the influence of the human factor on the quality of the result.If the profile of the saw tooth does not correspond to the profile of the sharpening disk, then at first the profiles of the teeth are formed over two or four passes, deepening the disk by one pass by no more than 0.1 mm. Further sharpening is in the usual order.
  • Ribbon saws operate two to three times longer, since the saw along the entire length is obtained with a completely protected and exactly the same profile of each tooth without bruises, micronerings and scs, that is, without voltage points.
  • Pylorama can work with its maximum performance, since the saw along the entire length is obtained with the same front and rear angles on each tooth. But, despite all the listed advantages, this method of sharpening was practically not used on sawmills for a long time.

This happened for the following main reasons:

  • Very high price. Therefore, such a machine was bought mainly by service centers.
  • Not very convenient technical solutions of the sharpening process itself. A warm room, special oil was required, only with which a weak oil pump could work. This oil began to burn with intensive sharpening, so a mandatory hood was required and much more.
  • But the biggest restriction was the inability to drag the profiles of tape saws of others, except Wood-Mizer, manufacturers, as Wood-Mizer made relevant discs only for its saws. There were no other manufacturers.

Photo 1. Wood-Mizer Study machine

One. Cheap group (machine price-15-35 thousand. Rubles). Some manufacturers of classic sharpening machines simply change the phases of movement on a fist. Now the disk is already moving along the tooth, but only up and down. This gave them the opportunity when installing a profile disk to sharpen the entire tooth at once. But none of them understood that to sharpen a saw with a specialized disk, it was necessary not only to change the phases of movement of the fist, but also to make the whole machine in a different class of accuracy. Many of those who contacted us for help have already come across this. Therefore, I want to immediately warn about the meaninglessness of the acquisition of such machines. The worst thing for the disk is the backlash of the machine. If they are (and they are on all ordinary sharpening and, accordingly, remain on those sharpening machines that simply, with the help of another fist, try to convert to work with the Elbor discs), then the disk begins to be unpredictably beaten on the front line, then on the posterior, then on the posterior and accordingly and break the profiles of the teeth of the saw. Then the sharp ends of the teeth begin to cut the disk, several times reducing its service life.

Backlash can ruin the disk after 500 m. So it turns out from those who have already purchased such machines. At first, sharpening goes well, but very quickly, an expensive embrace disk becomes inoperative (it is simply cut to the base of the front or risk cutting out). You need to buy a new disk, which is already becoming economically unprofitable.

In Fig. 3 shows the phases of the profile disk. He must enter into the profile of the tooth all at once and sharpen the whole plane. The thickness of the applied Elbor layer is only 0.25 mm. But this layer is enough for a long normal operation. If the front of the disk at the entrance to the profile crashes into the top of the tooth (rice. 4), then the sharp cutting edges of the teeth are relatively quickly pierced in risk coating or generally tear it off in this place completely to the base, making the disk unemployed. In this case, the breakdown of the tooth profile also occurs.

Dear group (machine price. 120 thousand. Rubles). These are the manufacturers who simply copied the Woodser machine. At the same time, they got the machine at the price of the original, and the quality of manufacture is the same or even worse. With this option, it seems to me, it is better to purchase a proven original. However, this is already deciding.

Sharpening in this way is especially relevant when the saw on the tape-leading machines, since the saw there, unlike the pylors, works all the time, without stopping, and any non-converse voltage points there affect much faster.

However, this method of sharpening is now economically beneficial and when preparing a strip saw even on one sawmill.

Here is an approximate economic calculation of the payback provided to us by the owner of one of the pylors.

  • The salary of the sharpener is approximately 10-15 thousand. Rubles a month. To prepare for one shift, 10 tape saws are required full time.
  • Small saw resource-sawing approximately 15-25 m 3 rounds on a trim lumber.
  • With poor or medium quality of the preparation of the saw, the productivity of the sawmill on the sawing of wood on the overlated lumber is usually 0.2-0.5 m 3 per hour of the round, that is, approximately 100 m 3 rounds per month.
  • Five strip saws are consumed on average for a month. At the average price of a saw of 800 rubles, the cost of them will be 4000 rubles.
  • The average cut 20 m 3 is multiplied by the number of saws (5 pcs.), we get 100 m 3.
  • We will take the average profit from 1 m 3 of the rubberized lumber equal to 400 rubles, with an average or poor quality of the surface and, accordingly, not the highest price for lumber.

Outlet (reward)

Socket is made from the tape and is presented to note the achievements. Such tapes usually have a pin, brooch or clip for a bridle as a fastener, with which the award can be attached to clothes, animals, walls or other surfaces.

Award tapes can be just a flat ribbon, flatly folded with tape or more bizarre manipulations with tape material, such as sockets. The outlet consists of a folded or assembled ribbon located in a circle so that it resembles a rose, usually with attached strap ribbons. Some tape outlets will also have loops, petals and stars as part of the design when using satin ribbons, velvet tapes, transparent tapes, Lamé tapes, tartan ribbons and print tapes, including personalized printed tapes for advertising a sponsor, event or reason for its conduct. Giving.

Information about the award is usually printed on the tape, such as the name of the event, a sponsoring organization, the place of accommodation (for example, first place, second place, third place) and date). Complex awards also include the name of the recipient, special motives and logos.

Awards in the form of rosettes from ribbons are of different sizes: from level 1 (1 layer) to large sockets (in standard configuration) of 20 levels. They can be glued or sewn, but the central discs always need to be glued with glue.

The ribbon outlet consists of discs on which cards are held to attach a corrugated tape to form tiers of sockets. You can add stars, petals and loops, then select the clasp, then the tails and then the central disk.

Rosettes can be used to award any type of exhibitions and events: sports, hobbies, study, animals, business and education.

Festive sockets are awarded in honor of the birthday of Valentine, Christmas, Easter, Halloween or other special cases, such as weddings, christening and even funerals. They can also be delivered with a strip mount that allows you to suspend sockets to display both sides, since some sockets are made with their backs to the back, forming two sides.

Rosettes are also produced not only in the form of a circle, but also in the form of ovals, squares, rhombuses, rectangles and hearts. Awards in the form of ribbons are also of different types, such as medals, belts and banners that can be personalized in many specialized and wholesale companies from around the world.

Flower sockets seem new to the market since 2012, when individual flowers are stylized in the outlet. Flower sockets still include non.Carcasses, cloves and outlets, all of which can be used as a gift or award, as a separate flower socket or as a bunch of flower outlets, depending on the case of its use.

DIY ribbon saw

About how to make a tape saw with your own hands on the Internet you can find a lot of materials, photos and videos. For example, the Canadian site of Matthias Vandela offers drawings of the machine almost completely made of wood. But let’s dwell on something less exotic, which can be done both in a home workshop and a small workshop in processing wood or metal.

Production of a bed

The initial stage is the manufacture of a bed. For wood saw, it can be wooden or metal, for metal. Only steel. You can cook it from a channel or corner. For a small workshop or workshop, this is not a problem. The dimensions of the bed are selected depending on the estimated size of the processed material. A normally sawing homemade machine can cope with a tree with a thickness of up to 350 mm and a metall of several centimeters.

Carrying rod. Channel No. 8, which is welded to the bed or fastened with bolts. It should be strictly vertical and fixed at least at two points in length to exclude the threat of deviation. When biting a saw, for example (which sometimes happens) or sawing large load material, quite large.

There is a horizontal desktop on the bed with cuts for the movement of the tape, ruler, emphasis, clamps and other devices for serving and retaining blanks. The height of the table from the lower stops is 0.7-0.9 meters. Star height above the table-0.6-0.8 m.

In the lower part of the bed, an asynchronous electric motor is installed with launch capacitors, connected by a belt transmission with a drive pulley of a variable diameter. If necessary, change the cutting speed, the wedge.Shaped belt is simply transferred to another diameter. The belt tension is provided by the spring stretch mechanism.

Assembly of the drive

To drive the tape, wooden or metal pulleys of the same diameter (240-260 mm) are used, which are fixed on the shafts planted on the bearings. The lower pulley is connected by a shaft with the engine drive. The shafts of saw pulleys are fixed on the bar. Lower. Motionless, upper. In the slot of the fixed tension mechanism. This allows the use of ribbons of various lengths.

From the bends of the tape, the machine protects the special mechanism of the damper, which is located under the desktop. Drawings of this device can be found on the Internet. Sometimes you can see tape saws with two dampers. From below and from above the working area. This is justified if the machine is designed to work with large.Sized workpieces or exceptionally high saw accuracy is required.

Lubrication system and protection

Lubrication system (adjustable) is installed above the desktop. The oil itself enters the saw blade in the required quantity, which is determined by experimentally for each homemade machine.

All working nodes where something rotates or moves, it is necessary to protect the casing. It is best to make them from waterproof plywood with a thickness of 10 mm. It will cost inexpensively, and polished plywood painted with enamel looks very good.

Starting system. Standard button with the possibility of emergency shutdown. It is advisable to perform the lower part of the machine in the form of a nightstand with a wide door, or even two. One serves to select falling sawdust, the second. For access to pulleys and adjusting the speed of the tape.

Making a strip machine for an experienced locksmith with your own hands will not be difficult. Part of the necessary parts and units can be taken from written.Off or dismantled machines of your own enterprise or buy on the market or on the Internet, part should be made by yourself. In any case, the machine made independently will cost two times cheaper than the factory, with the same level of performance and accuracy of adjustments.

Ribbon saw diving down

And the last. In order, but by no means for its intended purpose, many problems are created by the fact that the sharpening stone is not often and neatly refuel. This is not the most pleasant activity, and this can not be done, as well as everything else that is written above, if the result is not internal.

Due to the fact that cold weather concerns most of our country, we would like to pay your special attention to the cutting of the saw.

The first rule: the softer the wood rock, the greater the wiring, the angle of the hook and the height of the tooth. And vice versa: the harder the breed, the less wiring the angle of the hook and the height of the tooth. Remember that soft rocks in a frozen state are sawn like solid rocks. Typically, the most difficult moment in sawing logs is when it was partially frozen. Do not be aggressive in this case. Dilute the saws like that. As when sawing solid wood.

A chemical agent is required to saw a very tarry tree for periodic sawing a saw. For this purpose, detergents for dishes are used. Do not use diesel fuel for these purposes.

When sawing a very dry tree, do not use water, t.To. This leads to the swelling of wood. If water is still required, use it as little as possible.

Any equipment has its own operational period. This is an adamant truth. Even machines such as tape sawmill, eventually lose their primary characteristics. Most often, the “waves” become a signal of the breakdown. The quality of the material spoils and, therefore, you need to urgently look for the root of the problem. Buying new equipment is not the best option. Over, the cost of strip sawmills in Moscow can hardly be called cheap.

The first thing that comes to mind when the “waves” occur is the need to check the wiring of the saws of the saw. It will not be superfluous to pay attention to the angle of sharpening. In the spring, its optimal value is 12 degrees. The fact is that the woody material thaws in the warm season, that is, it is more easy to process with sharpening “12”. To exclude interference in saws, it is enough to experiment on several models with different sharpening of teeth.

Frequent causes of breakdowns of tape sawmill

How to Fold a Bandsaw Blade

All participants in the woodworking process understand how the result of their work depends on the quality of the equipment. By the end, if the customer wanted to get deep “waves”, he would ask to buy a cupivore in Krasnoyarsk and process an array to them. Until this happened, you have to analyze and look for the root of the problem.

“Exalt” can be for one of the many reasons:

  • Rails are incorrectly displayed. This provides the effect of “diving” and the uneven course of the saw;
  • Weakened bolts;
  • Worn bearings;
  • Weak tint of the belts;
  • Deviations of guide rollers.

Another reason for low.Quality work may be incorrectly exhibited tables. Oddly enough, almost no one pays attention to this factor.

Checking the height and inclination does not take much time, but it gives a tangible effect. In this way, it is possible to exclude not only “wave”, but also errors in sizes, lumber forms.

Settings are made using a conventional square. It is enough to compare the values ​​of each table when filing a sawmill.

To check the rollers, you need to push them as far away from each other. Then, using a compact level, their position is measured. If there is a slope on one of the sides, then the corresponding video pulls more strongly. However, all the above advice should not become a one.Time “action” to save equipment. Identification of problems should be carried out constantly. Only in this case, lumber will be really high.Quality, even, with a clear geometry.

At the entrance to the tree, the saw made “Backing up“, Then works exactly to the end of the log and falls down

This phenomenon is caused by too much angle of tooth sharpening

You can try to reduce the angle by 2 degrees

At the entrance to the tree saw go up, As a result, the output is a curve like a saber

Very large angle of sharpening with insufficient tooth divorce

Reduce the angle of sharpening of the tooth by 2 degrees and increase the divorce by 2-3 thousandth to the side

How to Close Saw-Cut Jump Rings

Br

The canvas of the tape saw machine is an endless (closed) metal strip moving on two or three large pulleys. Since the movement, and, accordingly, the pressure of the canvas is always directed to the desktop, there is no danger of return and release of part towards the master. For this reason, many woodworkers prefer a zircular banding machine, even though it does not perform longitudinal sawing or does not cut the fibers across the fibers as clean and quickly. The strip saw has other advantages. It can be used for curved sawing; The strip saw will cope with thicker wood than the average circular machine; The retreat in the form of sawdust is minimal due to a very narrow cut; And besides, a Band sawing machine is cheaper than a good circular machine. The Band sawing machine occupies a small area, and the models for home workshops are easy enough to install them in place without special lifting equipment. A good strip saw during work makes a little noise. An important quality if the workshop is part of a residential building.

Metabo desktop tape.Basic elements: 1. Handle of adjusting the tension of the saw tape, 2. Doors of the pulley compartments, 3. Door locks, 4. Handle for moving the fencing of the saw tape, 5. Switch, 6. Fencing of the saw tape, 7. Parallel emphasis, 8. Upper guide saw tape, 9. Emphasis for beads.

Large tape drifts are on the floor and have a solid support structure. Smaller machines are designed for installation on low stands. Tables, workbench, frames, etc.P. You can purchase such a stand as a component or additional accessory of the machine, or make it yourself.

The depth drank. A lot of tape.Saw machines are acquired due to the fact that the strip saw can cut thick blanks. A middle.Class banding machine for a home workshop saws a material with a thickness of up to 150 mm, and more expensive models have a maximum depth (thickness) of sawing up to 300 mm. A large saw thickness makes such a machine an ideal machine for sawing large wooden arrays on boards, rails or even sheets of veneer.

The width of sawing. The departure of the canvas of the Band saw. The distance from the canvas to the rack. Determines its maximum saw width. The departure of most tape saws for home workshop is in the range from 350 to 350 mm. If it is planned to process wider boards, apparently, you should buy a small model for industrial use.

The speed of the canvas. The speed of the canvas, or the speed of sawing, is measured by the amount of meters, which the arbitrary point on the canvas passes in 1 minute (m/min). For different models, the maximum speed varies from 220 to 1220 m/min. For cutting metals and hard plastics, a lower saw speed is set by switching the toothbler or smooth adjustment within the established limits. For sawing wood, the maximum speed is recommended.

Electric motor. Latu-saw machines for non-industrial use are available with electric motors with a capacity of 550-750 watts, which is quite enough to solve the problems of a home workshop.

Pipes. Almost all tape saws have two pulleys for a saw blade. Lower pulley. Drive, that is, directly related to the engine. Some models have a third pulley to increase the departure of the canvas. In such machines, the tension of the canvas is stronger, and therefore they more often fail. A rubber, cork or polyvinyl chloride bandage is installed on the pulleys to protect the drain of the saws.

Ribbon saws with two and three pulleys.

If possible, tease the machine with a stationary brush that constantly cleanses the leading pulley from sawdust, the accumulation of which leads to a slippage of the canvas. It is also desirable that the bearing of the pulleys be closed.

Directs of Polon saw. The guides of the blocks, or liners, hold the canvas from two sides and behind, so that it does not jump off the pulleys under the influence of the forces arising during the processing of the workpiece. One set of guides installed over the table of the machine is lowered and rises in accordance with the thickness of the workpiece. In addition, another set of guides is stationaryly mounted under the surface of the table. The guides for the canvas should allow you to exhibit very thin gaps.

The tension of the canvas. The tension of the canvas is regulated by the movement of the upper pulley up or down. On some machines, a scale is installed, showing the tension of the canvas, but usually the optimal tension is determined as a result of trial and the experience gained.

Fencing of the canvas. With the exception of the part that is open to work with the material, the entire canvas is inside the machine body. For an open part, a fence adjustable in height is provided.

Table of tape saw. Most of the tables of tape saws are made of cast iron, cemented steel or aluminum glory. Tables can be perfectly flat or have grooves to remove sawdust. The table of any strip saw leans at an angle to 45 ° for digging beads. The scale located under the table shows the angle of inclination. The middle table has the shape of a square with a side of 400-450 mm.

Tilt table.

Stop for longitudinal sawing. Direct longitudinal sawing is performed using a short adjustable stop. Very wide and long blanks can not be well fixed enough on the mocking machine included. In this case, the emphasis should be lengthened by fixing on it a larger, wooden. Sometimes it is useful to provide longitudinal emphasis on both sides of the canvas. Especially for longitudinal sawing of bevels, when the gravity will help to hold the workpiece pressed to the stop on the inclined table. In some machines, before the longitudinal emphasis, there is a depth limiter for cutting along the length of the spikes and other parts of the compounds.

Divorce of two teeth right away

Machines that divorce two teeth are immediately made of the following types: together with a sharpening machine; separately only a divorce machine operating from the engine; Separately, only a divorce machine with a manual feed in the form of a wheel (photo 1) or lever.

See illustrations In the PDF version of the magazine

Photo 1. A divorce machine with a manual feed in the form wheels

The machines for this option are most advertised by sellers, because they seem to facilitate the work of the sharpener, conducting the divorce of two teeth immediately on both sides of the strip saw. This is a very good advertising “noodles” for the ears of those who have never made tape saws on their own. Those who at least once prepared a saw for work know very well that each tooth on the saw is divorced individually. The tooth is always diverted with a pusher to a value, greater than the necessary divorce. When the pusher is withdrawn back, the tooth always shifts to some value back. Over, even for one saw, it can fluctuate backing back of each specific tooth within 5. 25 indicator units. Therefore, the sharpener almost always has to make two or three presses, often to different values ​​of the indicator each (that is, with different effort), to obtain the required divorce value. There are also teeth that spring worse than others and already at one or two presses before the indicator of the indicator, as on well-springing teeth, remain on values ​​that are large than the necessary divorce, and they have to be specially bend back.

Now you should understand that it is just impossible to make two teeth well with one pressing. But the machines are well sold, and some are even satisfied with the result. Drawing a saw on such a machine, you always need to know: you will never get a guaranteed good divorce of a strip saw. Divorce will always be unpredictable. With small feeds of the carriage, a accidental batch of a drank with more or less equally spring.Loading teeth, a new clean mechanism sometimes manages to saw normally. But problems necessarily arise later. But they begin to look for the reason for these problems anywhere, but not in the divorce, believing that he is very good. For almost all such divorce manufacturers, even indicators do not put. Explaining this by the fact that you install everything once, and then only breed: the hammers always beat the same and what to check here. And you check and see for yourself what a large scatter in the values ​​of the divorce actually.

In addition, the accuracy of the resulting divorce in these machines is strongly affected by the same reasons as in the classic ones: the getting of dirt into the mechanism, the risks on the pusher and support plates. The height of the diluted part of the tooth is especially affected.

Radius carriage for tape saw with your own hands

Production process. This device consists of only two main details. The rectangular P-shaped base was cut out by the size of the desktop table of the tape saw, and the cutout for the canvas is made in it.

The mobile part is able to rotate relative to the base to the right and to the left along the strictly defined arched trajectory.

The trajectory of the movement of the change of carriage is set due to the two small round pins crashed into the base.

A arcuate groove, which is a response element for pins, is professional on the bottom of the carriage. It is on the shape of this line that the resulting surface depends on the processed part.In this case, the radius of rotation of the carriage is approximately 300 mm.

Compensation for the size of the workpiece, as well as curvature of the resulting surface is carried out in several ways. In the first case, you can fix the workpiece in different places on the surface of the carriage.

You can also shift the base plate perpendicular to the plane of the canvas. Due to this, you can make concave or convex forms with a larger or smaller radius of curvature.

As already mentioned, for different cases you can make many options for the carriage itself. For example, such a double.Sided carriage with a wide sickle neckline in the middle.

Thanks to such a configuration, it becomes possible to place blanks and stops both before and behind the blade of the saw, as a result of which you can cut out from both directions. Over, on the one hand, they will turn out concave, and on the other convex forms. And there is no need to rebuild anything in the system.

The workpiece can be mounted on a carriage using double.Sided tape, or install additional stops on it. In this case, it is a simple M-shaped emphasis. Когда упор находится слева, а заготовка — справа от мастера, вырезаются вогнутые поверхности.Scraps just have a mirror, convex surface.

If the emphasis is placed on the right hand from the blade of the saw. Convex outlines are obtained.Of course, the arc of the grooves in the carriage can not be curved from the blade of the saw, but in its direction. Then the center of rotation of the carriage will be located on the other side.

And here it is the result. Two unusual caskets, cut out in just a few minutes. All external surfaces are symmetrical, and the products look very impressive.

But this is not all possible forms. The author sets on a supporting one another carriage with an even larger groove radius. A small piece of plywood is attached on the carriage. The latter will play the role of the stop. As you can see in the photo, the plank is screwed at some angle, which makes it possible to cut curly fragments.

Having cut off the first segment from the board, the workpiece turns over, shifts forward, and the operation is repeated.The main thing here is to remember that the angle of the stop relative to the axial line of the carriage should be certainly multiple of 360 degrees. In this case, you will get a perfectly segmented circle. If you need, for example, a circle of 10 segments, you mentally divide 360 ​​by 10 and set a plank-assault at an angle of 36 degrees.
