Ruchnyie saws

The basic types and appointment

In any house workshop should be, at least three-four saws of different type.

 • On a photo (top-down): big and small nozhovki; a saw with obushkom; a saw with a narrow cloth. At the left nearby - a saw for fair sawing up.

As a rule, the most running tool - nozhovka with a wide cloth for rough raspila large-sized details and preparations.

The the cloth is longer, the there is a work more fast. Hoever mobility of the cloth because of what a saw that is called, withdraws aside for the same reason increases. Therefore it is important to watch closely a line raspila, not supposing its deviation from a marking.

The novelty of the last years - teflon cover of a cloth nozhovki which considerably facilitates a cutting of a fresh tree, and also protects a saw from a rust.

The saw with obushkom differs from usual nozhovki not only that has a rigid nozzle which "extinguishes" cloth fluctuations, but also smaller, close standing teeths. Such saw allows to do pure and thin raspil.

 The saw for fair sawing up supplies an equal and accurate cut.

 The saw with a narrow cloth is intended for cutting out of the rounded off details and the big apertures.

 Key rule of care of any saw: its cloth always should be dry and pure.

 Saw teeths - even tempered - should be sharpened regularly.

For each preparation - the saw

Nozhovka saws fast, but the wide step of teeths keeps a rough trace in a soft material. On the other hand, it would be inconvenient to saw a thick bar a saw for fair sawing up. In a word, the material and the tool should approach to each other. Only then it is possible to expect for reception equal, free of defects a cut.

• From a tree, what saw it is better to saw what preparation

Teeths of a saw and their form

Saw possibilities depend on what sizes and the form at it a cloth and what size of teeths. The considerable quantity of the small, often possessed teeths supplies a thin cutting, but drank thus slowly moves ahead. The small quantity of large teeths gives rough raspil.

• So teeths almost at all manual saws are possessed, including nozhovku and a saw with obushkomWood consists of fibres which at a cutting are divided. Thus there is sawdust. The teeths more small, the has more fast spent on drink, and a cutting edge of a saw are hammered by small sawdust - pilnoy a flour. Teeths cannot seize wood in complete height any more, the Cutting becomes more and more tiresome and, the main thing, unproductive, And here large teeths practically never get littered thanking bolshey remoteness of their tips from each other.

Almost at any saw teeths are dissolved, that is their tips, serially deviate that to the left, to the right. The more an inclination corner, the more widely a strip has spent on drink, and consequently it is less hammered by sawdust, and a saw gets jammed less.

In process of use tupyatsya, and them it is necessary to sharpen saw teeths. The infringed distributing should be thus restored. Even for the expert it not simple work. Therefore we recommend to acquire saws with the tempered teeths. They not so it is fast tupyatsya, and to sharpen them easier, than teeths of a usual saw.

It is necessary to put only a saw cloth on a table and grinding bruskom to conduct on a cutting edge from the end to the handle twice, then a cloth to turn. The saw is ground, it is possible to start to work.

How correctly to saw

To saw it is necessary always from an outer side raskroya, closely to razmetochnoy to a line. It concerns both rough raspilov nozhovkoy, and exact raspilov with a saw with small teeths. Further it is very important, that sawn preparation had a stable support in the form of a table-top of a workbench or a usual desktop. For large-sized preparations it is better to use goats. In the course of a cutting a detail it is necessary to hold strong all time with a hand (large-sized preparation - also a knee) - differently, the saw should move only.

Cutting begin with the first short movements under a corner from 30 to 45 degrees. Only after the saw cloth has entered into wood and was fixed in it, it is possible to begin work as a saw for all length of a cloth.

At cut edge saw only short sharp pushes. It will allow to avoid oblomov from the bottom party of preparation.

Has spent on drink along wood fibres - always a "critical" situation, especially if wood with big svilyu. The saw wants, naturally, to go on a way of the least resistance and if it not to constrain, it will start to "walk". That is in such cases it is necessary to press a saw more strongly, than usually, that, in turn, requires as much as possible stable position of preparation.

At big cross-section raspilah usual nozhovku can jam. In such cases it is better to use a saw for a longitudinal cutting with hardly dissolved teeths. Only it is necessary to consider, that the strip raspila will be much thicker than a saw cloth.

How to protect a saw from damages

Any saw (especially its teeths) should not adjoin in a storage time to other tools. From such neighbourhood it can fast fail.

If the saw does not have cover to protect its teeths from damages the simple method will help. In a hose piece do a cut of the necessary length, then a hose nasazhivayut on a saw cloth. Is better for this purpose the rigid hose fitted from within by a fabric will approach. It is densely kept on a saw cloth even after repeated use.
