Scriber– carpenter size precision instrument, which replaced the line.

Time does not stand still and makes its own improvements to carpentry tools. When marking with a line, the most difficult thing is to ensure a strictly vertical position of the marking ends of the line. Canadian inventor, one of the authors of the technology " Canadian cutting", Robert Chambers proposed a marking tool in which verticality is ensured bubble levels. He called it ChambersScriber.

The talented Russian carpenter Yuri Milykh developed his own version of the scriber, which he called carpenter's compass. Based on his motives, my homemade product was made.

Main reason self-made- the high cost of this instrument (300 – 500 US dollars).

To make a scriber you need the following tool:

1. Hammer
2. Hacksaw for metal,
3. Vise,
4. Grinder with cutting and grinding discs,
5. Welding transformer,
6. Drill,
7. A set of needle files - files,
8. Taps and dies with a diameter of 6, 8, 10 mm,
9. Plumb (to adjust verticality),
10. Level (to adjust the horizontal position).

The scriber is made entirely from scrap materials. It cost me $2 (the price of nuts and washers) and two days of wasted time.

Well, now, the manufacturing process in pictures.

Photos of the finished structure.

During the marking process, the problem with a regular pencil is that the lead wears off. It has to be constantly sharpened and pushed out. Since the scriber was adjusted to a certain length of the pencil, in order not to make mistakes when extending, a special template was made (at the same time a screwdriver and a 10mm head).

When cutting a log house, you must strive to ensure that the gaps between the logs on the sealing grooves and cups are as small as possible. This directly determines how warm the house will be and how much moss and tow will be needed to seal the cracks. There are no two identical logs, each log in a log house is unique, so it is impossible to create a single template for marking all the logs at once. This is only possible if you have to work with material planed under one size, such as, for example, a rounded beam. But this is impossible to do with a “wild forest”, and each log has to be approached individually.

The most important place in the arsenal carpenter's tool, along with the ax and the staple, is occupied by the devil. The line is intended for marking corner connections in the log house (cups) and longitudinal grooves in the logs (dolov). Also for marking blocks and boards, for their tight fit to each other. The earliest finds of features in Veliky Novgorod date back to the 11th century ( Ancient Rus'. City, Castle, Village).

The design features are very simple: it is either a metal plate with triangular cuts at the ends,

or a two-pronged fork with curved ends,

or a metal bar unforged in two.

The line can be bent, for example, from thick wire,

or simply drive two nails into the wooden handle at an angle. You can also use a plumber's compass instead of a line.

The smaller the distance between the teeth of the line, the greater the accuracy of the marking. Marking with a line requires some skill.

When drawing the teeth, the lines must be strictly oriented horizontally and vertically; any deviation or tilting results in an error in the marking, due to which the log either does not fit into the groove, or, on the contrary, a gap is formed. Accurate marking skills come with experience, but progress does not stand still, and the classic carpentry trait is being replaced by a new, precise tool - the scriber.

In fact, it is a mechanical compass on which the level is set. The level helps to keep the line strictly in the horizontal and vertical planes, thanks to which it is possible to avoid errors and the markings are very accurate. From personal experience When working with a scriber, I can notice that the accuracy of the logs is so great that a match cannot fit between them. But since our task is to build reconstructions of houses for the “Seven in the Past” project, we have to use traditional tools!

Scriber is a carpenter's marking tool that replaced the carpenter's line.
This is a tool for drawing crowns in the process of cutting log houses. Drawing logs requires skill, since the quality of the felling depends on the firmness of the hand. For the accuracy of the “landing” of the upper crown, the line must be drawn evenly and without deviations from the horizontal and vertical. With the help of SCRIBER, deviation from the horizontal and vertical planes can now be controlled visually. This allows, with a careful approach, to make just one drawing

Assembled weight:
450 grams
Equipped with level:
type 2D (cross spirit level, 1 vertical and 1 horizontal)
Dimensions:
length 270 mm; width 190 mm; thickness 40 mm.
Works on solution:
from 24 to 360 mm Main parts: “legs” are made of aluminum alloy, which are heat-treated (increased strength) and coated with anodization - an anti-corrosion coating. The rest were made of structural steel and coated with an anti-corrosion coating - zinc. The repeat holders rotate on thermoplastic washers, which greatly reduces friction when turning. The design of the holders allows you to work with pencils and Fischer rods. Manufacturing technology using programmable machines allows us to obtain precise parts, which in turn guarantees high marking accuracy.

Carpenter's trait is a marking tool for wooden surface parallel lines, straight or curved, along which logs are cut or building forms are made. On one board, carefully remove the edge, then use it to apply a marking line on the next strip, which is leaned against the first.

The metal tip leaves a deep longitudinal mark along which further work is carried out.

Features of the carpenter's trait

Working with a carpenter's mark requires care, as the scratch cannot be erased like a pencil mark. Another job that do with the help carpenter's trait, is a sample longitudinal groove for a tight connection of logs in a wall frame, a log bowl before subjecting it to final processing. The line is used for beating and drawing an even line on the block when planing, processing the boards for their tight fit. The tool is used for marking joints and various marks in carpentry. At the same time, a carpenter's compass is used.

In ancient Russia, when cutting down the walls of houses and churches, carpenters used only an ax and a line. To connect the logs, unique grooves were used that did not require the use of a chisel and chisel. This demonstrated the individual methods of skillful work of ancient masters.

Subsequently in wood finishing The line is replaced by a surface planer, which translated from German means a device for drawing parallel straight or winding lines. This tool is used to copy dimensions from one shape to another part. The difference between the two devices is that instead of a wedge and a line ring, the thicknesser has a moving block with a screw lock.

Drawing principle

Process drawing crowns during the installation of walls requires special skill of a specialist, because the quality of the constructed log house depends on his precise work. Deviations vertically and horizontally when drawing lines are unacceptable; moreover, in the process of work they first make rough markings, then the final clean drawing.

For the production of high-quality logs carpenter needs a lot of time. Currently, the carpentry trait has been improved, and almost new tool, which is called a scriber. Drawing contains the following steps:

• installation of the log of the upper belt, adjustment on the linings horizontal level, alignment of the vertical axis of the ends;
• after this comes the drawing stage, which consists in spreading the ends of the scissors to a certain distance, taking into account the thin end of the log, this is done this way, because if you start with a thick butt, then the longitudinal groove may not reach narrow section;
• You need to draw a line along the level, therefore, moving the needle and pencil to the lower end and the upper end, respectively, looking at the bubbles in the device, move the scriber along the log. The same method is used to draw cups.

Possibility to make a tool with your own hands

Simple Trait Option made of wire thick diameter. A similar solution is to drive two long nails into a suitable wooden handle. A mechanic's compass is also used to mark wood. The accuracy of drawing increases as the distance between the teeth of the tool decreases; skill and experience play an important role.

Scriber is a compass mechanical action with built-in level. The latter is intended for precise marking of lines horizontally and vertically. If everything is done correctly, then marking with your own hands will allow you to assemble the log house in such a way that it will not be possible to push a match between the logs.

Scriber is an advanced carpentry trait that has been given two levels. This saved time for the carpenter. After all, now they don’t draw a rough line for marking, but immediately draw a finishing mark.

Carpentry Feature Improvement

Time works to improve the instrument and does not stand still. When drawing markings, the main thing is to ensure horizontal and vertical correspondence lines; for this, the ends of the carpentry line are set using level bubbles. A Canadian inventor proposed an innovation in the form of a marking tool based on a carpenter's line, which he called a scriber. The Russian skilled carpenter did not further elaborate and developed a different version of the scriber, which later became known as the carpenter’s compass.

Tool for making a modern carpenter's dash

To make it yourself you will need the following tool:

Make it yourself carpenter's compass can be made entirely from scrap materials located nearby. You will only have to buy the appropriate washers and nuts in the store, if they are not in the home craftsman’s storerooms.

The basis of the tool Old, out-of-use metal scissors were put in. Carefully cut off the bolt heads and attach them by welding to the handles of the scissors. To install the pencil and needle mounts, use the threads on the ends of the bolt.

They make a socket for installing the needle and the needle itself, then design it further. The device for installing a pencil is designed in such a way that in addition to it, a needle can be placed in the mount. Flasks with bubbles are taken from old building levels, you will need two of them, for the horizon and vertical.

To determine needle dilation amount and a pencil there is a bar for adjustment. It is fixed with nuts, and the compass is secured in the extended position with clamps made of bolts and washers. To secure the levels, a mounting platform is made. During operation, the pencil lead is ground down, and when the compass is pulled out again, the compass may get lost, so a special template is created, which provides for a joint design of a screwdriver and a head. Alternatively, you can use another needle instead of a pencil.

In conclusion it should be noted, that if carpenters have used a line for marking for so many centuries, then this tool will be popular in future years, so you can make it yourself and use it to ensure high-quality markings when working with wood.
