For those who know nothing about carpentry, there is no difference between a scherhebel, a plane and a jointer. The tools look, in fact, very similar and are used in the woodworking process. However, there are differences between them, Our tips site will tell you about them.
And the scherhebel, and the plane, and the jointer, intended for manual work, are structurally very similar. All of them consist of a sole, last, blade, adjusting screws and two handles for working with both hands, which provides the necessary pressure of the tool.
Important! The body of the instruments can be made of wood or metal. Wooden tools are used for processing soft wood, metal – for hard.
The main difference between a scherhebel and a planer and a jointer is the blade. In the scherhebel, it is semicircular, oval, leaving sufficiently deep grooves and allowing you to remove a thick layer of shavings – up to three millimeters. Accordingly, the opening for the removed chips is also larger. In addition, the scherhebel has a narrower and shorter box design..
Scherhebel and plane
There is also a significant difference in the angle of the blade. In the scherhebel, it reaches 45 degrees, that is, the maximum deepening is achieved. The jointer removes chips at an angle of 13 degrees, the slope is minimal. Planer – at an angle of about 30 degrees.
If we talk about wood processing processes, then all three tools are used at different stages:
- The Scherhebel is the “heavy artillery”. It is used at the very first stage of rough wood processing, immediately after using an ax and a saw, a hacksaw. With the help of it, it is impossible to achieve a perfectly smooth surface, but the preparation for further processing takes place quickly and efficiently.
- The plane is used after the scherhebel, it can, in principle, replace it, but it all depends on the condition of the wood and the purposes of its processing.
- A jointer is a tool for finishing a workpiece. It is he who allows you to achieve a perfectly smooth surface, removing small chips.
The jointer is much longer than the planer and scherhebel. It is intended for leveling large surfaces. The second design feature is the presence of a double knife. In addition, the jointer knife has a chip remover to ensure the smoothness of the wood after this finishing step..
Important! The blade width of the scherhebel is 35 millimeters. And the jointer can be up to 80 millimeters. The length of the jointer block is 50–90 centimeters.
We state: the scherhebel is used exclusively for rough wood processing. Its small, rounded blade provides the deepest possible penetration into wood, because it protrudes from the block by two to three millimeters and has a reduced width. On the contrary, the wide jointer blade literally slides over the surface of a flat piece of wood, removing the slightest irregularities. The plane is one of the more versatile tools.
Important! In a carpenter’s workshop, there will definitely be a scherhebel, a plane, and a jointer. The use of all these tools will allow you to process wood in stages and with the highest quality.
