How to plan properly: 7 tips from the professional
- Fixation and stand: In order to achieve clean results at all, you must securely fix and clamp your workpiece. When fixing your workpiece, make sure that it is placed at a working height that is comfortable for you. By the way, you should always have a firm stand so that you can carry out long planes safely.
- Correct setting of the knife: Usually, the electric planer is already supplied with two mounted hard metal reversible blades. Should the blades become blunt over time, replace them, since carbide reversible blades cannot be resharpened. You can find out exactly how to change the blades in your instruction manual. Whether the blades are set correctly can be seen from the fact that you get a smooth surface after planing. If notches or grooves are formed, the cutting edge of the planing blade and the base plates are not properly matched to one another.
- The right depth setting: Before you can start working on the wood, you have to adjust the cutting rate on your device. On the electric planer models from Einhell, you can adjust the cutting depth with the help of a rotatable adjustment knob between 0 and 3 mm in 0.1 mm steps. You should always keep one thing in mind: The lower the cutting depth, the smoother the surface is planed at the end.
- Working with the parallel stop: You're about to plan with a guide? Then this parallel stop is handy! This is attached to the side of the device, as explained in the instructions. The parallel stop can then be used to set the step width, which can be particularly helpful when planing steps. The stop is applied to the edge of the workpiece and the planer is then guided slowly and reliably over the workpiece.
- Always work in the fiber direction: You should definitely pay attention to the fiber direction of your wood. If you plan against the direction of the wood fibers, you create eruptions in the surface. If you work the wood in the fiber direction and nonetheless produce uneven results, it is preferable to work more often and with less cutting depth over the workpiece. With gentle pressure and a slow feed, you should achieve clean results.
- Apply little pressure: Generally, when working with the planer, you only have to exert a little pressure on the device, but you should distribute it correctly. At the beginning of the wooden surface, press the front of the device, towards the end of the surface, you move the pressure to the rear of the device. This prevents you from planing the workpiece in the shape of a ball, i.e. removing more wood at the beginning and end of the wood surface.
- Check with the spirit level: Whether you have actually planed flat, you can easily check with a commercially available spirit level. If your surface is not straight at the end, you can simply touch it up again.
How to avoid cracks and unevenness?
If cracks occur in the wood when using the electric plane, there may be a number of reasons for this. Often it is due to a cutting depth that is too high, that is to say to the fact that you remove too much wood at once. In general, we recommend that you set the cutting depth rather low and prefer to work several times over the wood and plan it layer by layer. By the way: The harder the wood, the lower you should set the cutting depth!
Not too fast and with gentle pressure, so that the speed is not reduced by pressing too much against the wood, you should push the planer over the surface in the fiber direction. We have already briefly explained how to avoid your workpiece becoming "crowned": At the beginning of the wooden surface, the gentle pressure should be exerted on the front of the plane, towards the end of the surface, the pressure shifts backwards.
If all these tips don't help, then you should definitely check your planer's blades - because with blunt blades, you won't achieve even and clean results.
