Manufacturers
For those who like to buy exclusively factory tools, the main manufacturers should be listed. First of all, it is the Russian company Petrograd. The staples made by the craftsmen of the domestic artel are in steady demand among carpenters. They are reliable, durable and easy to use.
Also cororders are made in China and supplied to the domestic market. Imported plows are fundamentally different from Russian tools. In such samples there are mechanical parts, adjusting elements to increase the productivity and comfort of the carpenter during work.
The braces are also produced by the German company BETEK. Coroders are made of carbide (cutter tip) and steel (head and shank). High-quality soldering of materials is ensured through the use of innovative technologies and special solder. During operation, the tool heats up and expands, depending on the chemical properties.
Staple
I was prompted to master this tool by a case when a friend presented me with several bags of shed rubbish left over from a father-in-law, a well-known artisan in our district. Crazed with luck, I took out from my bags either a rare selector, or a set of cripples - a true gift of fate, and even a surprise - a curved forged knife, shaped like a sickle, with two vertical handles. This outlandish tool turned out to be a scraper, which I saw many times in the pictures, but did not have to hold it in my hands. Immediately, intuitively taking it in my hands, I tested it on a log and realized that I wanted to master the work with it.
It turned out that the scraper is much older than I could have imagined. Already in the Middle Paleolithic, people used a stone scraper, flint blades with an inwardly beveled arcuate working edge. With the advent of iron in everyday life, the scraper takes on a familiar form for us and no longer changes. He served for stripping, scraping the bark.
It is the peeling, not the shearing of the material, that has defined such a long life for this instrument. Let's remember the structure of a tree: bark, cambium, bast, sapwood, core and heartwood. The cambium layer and the bast part of the tree are the natural protection of wood from external influences. It is the preservation, and not the cutting of the bast, that is the main task of the work with the scraper.
Prying off the bark and peeling it off, the scraper crushes the back surface, smoothes the bast to a characteristic shine, compacting and leaving the wood intact. The movement of the scraper is possible only along the cambium, since it is soft and loose in structure, and it is completely unacceptable for the instrument to get stuck or split the wood.
The movement of the scraper is directed towards itself, by the effort of two hands, smoothly and without jerks, in order to tear off rather than cut the material and, of course, along the growth of the fibers, from the butt to the top. After scraping with a scraper, the surface of the wood takes on a characteristic, waxy white color. The wood begins to shine as if it had been waxed or varnished.
If such a visual effect is observed, then the technological process is performed correctly.
The walls of a log house made of logs "treated for a scraper" usually no longer need additional protection and attract attention with their unique and natural beauty
Don't know why primitive? Having slightly sharpened the cutting edge, it is very convenient for me to trim, clean and adjust the thermal groove when knitting a log house with a scraper. Yes, I clean and adjust the corner bowls for them.
But this is more an exception than a recommended practice. Since the proverb is still alive: “after supper mustard, that after the scraper - an ax.
In the recent past, debarking logs under the scraper was widespread, since people tried to use natural protection as much as possible, without having invented impregnation yet and performing many operations by hand.
Today, many firms also offer their customers a "scraping" log, but in practice they remove the layer by planing, rather than crushing the bark with scrapers until the bast shines.
Such a log is sold, of course, more expensive, and if you agreed to pay for this work, try and control it.
How to do it yourself?
Professional carpenters often prefer to work with hand-made tools. They also teach their students to this order. Therefore, it makes sense to tell briefly how to make a reliable, beautiful staple that will be convenient to use.
First, you need to prepare blanks, tools for woodworking - a hammer, a Japanese saw, clamps, and so on. Also have on hand:
- pencil;
- wax;
- screwdriver;
- knife;
- square;
- ruler;
- thickness gauge.
Think over the dimensions of the plan and draw a drawing. After that, you can start to work.
Procedure:
- first you need to cut out a bar, process it, bring it to the required parameters;
- transfer the dimensions of the previously drawn template to the workpiece;
- mark the place for fastening the iron knife;
- drill technological holes, cut threads;
- screw in the elements for fasteners;
- install a knife (can be made from a spring) and circle the contour;
- apply markings for the manufacture of a taphole;
- remove the knife and apply the markings;
- cut out according to the contours;
- remove excess wood for mounting a knife, also brass plates;
- measure the taphole, transfer the required dimensions to the plate;
- cut and grind off one edge at an angle of 45 degrees;
- drill a couple of holes in the plate;
- screw a knife to the plate;
- dismantle the mount and the cutting part;
- cut the handles on both sides;
- cover the wooden parts with varnish, let dry.
The final step is to install the knife and fasten it firmly with fasteners. Corder can be used.

What is a staple?
The carpenter's scrapbook is an ancient hand tool designed for woodworking. Products differ, first of all, in the shape of the knives - straight, curved. There are wooden handles on both sides of the metal blades. They are necessary to make the plow convenient to use. The master, in the process of work, scrapes the log, that is, rips off a thin layer of shavings.
To work with a scraper, you need to have considerable physical strength, because in the process of scraping wood, a large group of muscles of the whole body is involved. Processing with a tool is considered rough, but the required actions must be performed carefully.
Here it is important to remove the bark, partly the bast and leave a useful layer of wood to prevent rotting, the spread of fungus, mold
The movement of the plow is carried out:
- smoothly and towards yourself;
- with two hands with characteristic effort;
- to the top, along the growth of the fibers;
- the soft and loose layer of kabmiya is scraped off.
It is forbidden for the tool to cut the material, get stuck or create crevices in the process. After proper planing, the surface of the wood begins to shine.
Device and purpose
The staple is designed exclusively for woodworking. Such a simple instrument, despite its primitive construction, has great advantages. Using the device, you get:
- excellent cooperage crafts;
- cleaning logs without damaging the sapwood;
- other carpentry work.
If the house is made from a log house, after finishing with a scraper, the logs do not need constant processing. They also do not deform during shrinkage and do not crack over time. An additional plus concerns aesthetics.Such a classic method - scraping - will certainly add naturalness, a pronounced effect of originality to the interior walls.
It should be clarified that the scraper-plane strips off the excess wood, and does not cut it off. The main task of the carpenter when working with hand tools is to preserve the natural natural protection of the logs, or rather the layer of kabmiya and the bast part. And this can only be achieved by scraping, not cutting off the layer.
