During the work with tree it is impossible to do without plane. Only by means of this tool it is possible to receive smooth and plain surface. The classical design of plane has a little changed with centuries and still when choosing the tool it is necessary to pay attention to its main characteristics.
Instruction
1. Pay attention to plane sole. The purity of processing of sole is higher, the friction when processing surface is less and work turns out better.
2. On sole of plane there have to be longitudinal furrows which prevent formation of air pillows between sole and surface. The airbag is the reason of uneven pressing of the tool to tree that leads to uneven removal of shaving.
3. Choose plane on which front surface of sole V-figurative deepenings for chamfering are cut through. The sole of plane has to be separated into two parts: the lobby - mobile, setting cut depth, back – motionless, holds plane in the necessary plane during the work.
4. The best the plane with two handles, but not with one is considered. The front handle serves for task of the direction and its keeping during operating time.
5. The back handle transfers effort to plane. It has to be convenient and correspond to brush anatomy. On the back handle of electric plane usually there are "start-up" and "stop" buttons - it provides convenience of work.
6. Pay attention to adjustment of depth of cutting. Usually the step of adjustment makes 0.1 mm. But in some models of planes even with the exposed cut depth ""zero"", the tool all the same peel shaving. Therefore choose model which does not have this effect. Adjustment of depth of removal of shaving is made to bowl of all by the front handle. The mechanism of impossibility of change of depth of cutting during the work has to be provided in it.
7. For plane those which are made of tungsten carbide are considered as the best knives. They work to regrinding much longer, keeping at the same time necessary purity of the processed surface. It is simpler to insert carbide knives in knife carrier.
8. Have not bad proved also knives from alloy steel. But they demand quite frequent sharpening and they need to be leveled in addition after installation.
9. Pay special attention to types of protection of knives – them has to be a little. The mechanism the preventing contact of fingers with knives has to be surely provided. Also protection has to exclude unauthorized contact of knives with the processed surface.
