    Planing wood

    Planing wood

    Planing wood consists in cutting a thin layer in the form of a chip from the wood surface. Because the planer knife is quite wide, the surface of the wood is smoothed and leveled during planing. We give the wood a specific shape, necessary to make the intended structural element.

    The wood can be planed in all directions. However, we do not recommend cross-planing, which is quite difficult, because it requires a very sharp knife, special fastening and protection of the planed surface, in addition, it can always end up splitting off a piece of wood, which inevitably leads to the destruction of the workpiece. However, starting to plan along the fibers, the workpiece must be clamped very carefully, for example, using the carpentry board discussed in the previous chapter. The grain of the wood should be carefully observed and the direction of planing should be determined, otherwise it may happen, that the planer knife will scrape the surface of the wood instead of leveling it.

    The figure shows a trackpad plane. This is what should first of all be found in a home workshop. This plane consists of the hull (1) made of hardwood and fitted with a handle at the front (2), and on the back with a metal stop (3). There is a knife in the hull cutout (4) secured with a wooden wedge (5). The cutter plane should have a cutter equipped with a chip deflector.

    Preparation of the planer for work consists in ejecting the knife blade, after sharpening it first, on 0,1-0,5 mm below the working surface of the hull. To loosen the knife, hit the bumper with a steel hammer, holding the plane in his hand with the blade facing up. Place the loosened knife correctly in the fuselage cutout and fasten it by hitting the wooden wedge with a hammer. Sometimes the adjustment of the blade projection has to be repeated several times, until the desired effect is achieved. Let's remember, that the extension of the knife and maintaining the parallelism of the blade in relation to the lower one, the working plane of the hull has a great influence on the quality of the treated surface.
