You can cut very even the pros and cons of good jigsaws with a jig saw, if you have little time to do the advance work. It is very important that you slowly drive through the material, without exerting any pressure. If the stock of saw OK and the jigsaw fell not down or off the roof, has been left with the blade forward, you can begin immediately with the work. Especially a new and sharp saw blade is important, where you pay attention to the recommended material – for example, metal saw blade suitable for metal. If the cut is not straight, most of the time the blade stability is the reason, because especially with the thickness of 20 mm and the typical distortions and uneven degrees of hardness in the wood cutting is not so easy. When it comes to a hard body, the blade’s gone faster than you can imagine. More information about jigsaws see is on werkzeugcheck.de at the thicker boards, so one No perfect solution saw as a circular saw much better suited.
Also you can try to cut slowly with the orbit shot on the lowest level so you can usually just cut. If you press too hard, the cut is not straight and the blade runs away. Otherwise the leaning saws may be also because that the leadership of the blade is worn out or that the blade is generally wrong, because then you need not be surprised, if the cuts look wrong. In Germany, you will find 3 more or less standardized head shapes to each machine. If you not just can cut, it might as well, that the blade is bent or that the saw blade mount is not well aligned (must go always along the Guide). Especially in a parallel section, it is important, how it leads the jig saw or the blade. The best application of the parallel stop proves to be, how you will find it at the many jigsaws. If the jigsaw has the necessary width of saw good, so can fast, reasonably accurately select the correct saw blade. Frank Borchers
