Everyone who has ever handled a block or even a wide board by hand knows what tools are often used for this. Most often they take "just a plane." Even in schools, labor is given to work with this tool. But a professional carpenter knows that in fact these planers are divided into several types. In this article, we will try to understand this woodworking forest and touch mainly on the very first tool used in the work - the sherkhebel.
Joiner sherbel
We will figure out what to do when there is a curve board, unprocessed. As soon as a piece of wood falls into your hands, and especially if it is wide, like a board, you should take a woodworking tool called a sherkhebel. It is used primarily. Simply put, sherbel is a planer for rough roughing. It is necessary for planing raw wood to give it the necessary shape and size. Greater accuracy or a smooth surface will not work. There are other types of planers for this. Rather, shekhebel is not even a planer at all. But its appearance and principle of operation, which is extremely simple, are similar to a planer.
Diversity
According to many indicators, sherhebeli are different. They can be designed for different types of wood, which makes it possible to sharpen a knife less often, which grinds over time, and can also be made of various materials themselves. Even from a tree of more solid breed.
The physical indicators of the body of the sherbel are not very different and important, but the material from which the knife and the sole of the tool are made play a big role. Of course, it is not so much in accuracy, because, as we know, this parameter is not applicable to the described tool. The importance of metal affects how often a joiner will have to sharpen a knife so that it glides easily, removing such a thick layer of wood. It is also worth periodically checking to see if the sole plane has tilted. This happens if one side is pressed harder than the other, and especially when the fiber hardness of the treated wood and the sole itself do not match. Of course, few fans follow this, if at all, know what kind of instrument it is. Therefore, consider the average sherbel from the Russian online store.
The choice of sherbel
Its cost is not more than four hundred rubles. The average person, going to a site with good tools, may choose it. So, its length is 250 millimeters, the width of the sole is 43 millimeters. With these sizes, its weight is also small: a little less than eight hundred grams. If the width of a little more than four centimeters seems rather small, then the width of the knife is even smaller. At this shecherbel the width of the knife is three centimeters. For those who know, we will determine that the knife is made of steel grade 9HF, this is tool alloy steel of increased corrosion resistance. In simple words, the knife will not rust too quickly, and this is a common problem for closed workshops, where it is very humid. In principle, the main thing is to look for tools not by cost, but by reviews or personal experience. If you know that it is more convenient to work with a tool of a particular company than from another manufacturer, then it is better to take it. So the tool will last much longer, and it will be much more pleasant to work with it.
Distinctive features of sherbel
So what is the difference between a planer and a sherbel? As mentioned earlier, it is intended for roughing. Also from the plane the sherbel is distinguished by a semicircular sharpening of the protruding part of the blade. In addition, the blades differ in their width. At sherchebel they are somewhat thinner. According to the position of the blade, they are fixed at the shekhebel at an angle of forty-five degrees to the sole and protrudes from it by two to three millimeters. This means that they can remove the surface in a couple of millimeters by making a round furrow in the wood. It is also much simpler than a planer. He has a knife attached to the body with only one clamping screw. If you correctly tighten it, then the knife will not leave anywhere in the cutting process.
Jointer
As already mentioned, sherbel is the very first tool when working with an unprocessed piece of wood. But there is one more unusual for a person who is far from a locksmith's workshop. Its name is a jointer. At its core, it is much closer to planers, since its movement occurs only along the fibers, along the cutting of boards or bars. In appearance, there are also differences. The most important difference between a jointer and all similar tools is that it has not one, but two whole knives. Also, its length is much longer than the rest, not counting the extremely accurate planers, in which the sole area retains strictly one plane. The difference is significant, but it was necessary to understand, because the jointer is also an unusual woodworking tool.
Sherbel work
Work with this tool is not easier than any other. Since the purpose of the sherbel is to remove large irregularities, it is worth remembering that it helps not to remove irregularities, but only to thin them out, to make them more streamlined, then to remove them with another tool. Its difference lies in the fact that it can work both in fibers and at an angle.
By movements at an angle of about forty-five degrees, pressing from above, we pass through the entire necessary area until the entire surface is covered with uniform serifs. Then you can expand the board or go to the other side of the carpentry workbench on which the processing is performed. This is necessary so that the angle of the cuts is made mirror-like with respect to the longitudinal axis and such serifs again pass through the entire surface. There will be nothing wrong if you walk a couple of times along the fiberglass. But in this case, you need to check the plane more often so as not to leave too hard and not spoil the workpiece.
The optimal yield of the knife is one that removes about one millimeter, so the work will be much more convenient, you will not have to put much pressure on the tool, since most of it will make it weight sufficient to facilitate the work, oddly enough.
Also sherbel is a good way to make a relief surface for any artistic purposes. To do this, simply configure the departure of the knife (or "piece of iron", as it is called joiners with experience) and apply the notches that are needed.
