When cutting shallow grooves in soft woods such as pine, a faster rate of feed can be used. When making cuts in hardwoods such as oak, a slower rate of feed will be required. The best rate of feed is one that does not slow down the trimmer motor more than one-third of its no-load speed. If the trimmer is fed too fast, it will take large chips out of the wood and leave gouge marks. If the trimmer is fed too slow, it will scorch or burn the wood. PROPER FEEDING The right feed is neither too fast nor too slow. It is the rate at which the cutter is being advanced firmly and surely to produce a continuous spiral of uniform chips or a smooth trim edge on laminate. If you are making a small diameter, shallow groove in soft, dry wood, the proper feed may be about as fast as you can travel your trimmer along your guide line. On the other hand, if the cutter is a large one, the cut is deep or the workpiece is hard to cut, the proper feed may be a very slow one. A cross-grain cut may require a slower pace than an identical with-grain cut in the same workpiece. You will learn by experience from practice and use.
