A wood jointer can remove these imperfections very quickly usually in less than a minute if not seconds. Then when a piece of lumber is laid next to another piece they fit together smoothly and precisely. A tight 'joint' is formed. Hence the origin of the word 'jointer' a tool that can form a tight joint. The carpenters of old could only marvel at what a modern wood jointer can do in a few seconds!
If you were to look at a piece of fine furniture made out of individual pieces of wood, you would probably see a board on the left side being the same size as the corresponding board on the right side.
The depth of cut is determined by the height of the infeed table with reference to the outfeed table. The lower the in feed table, the more wood is removed with each pass over the jointer. It is not a good idea to take off too much wood with a single pass. The chances of tear-out increase with the depth of cut and you may end up removing more precious wood than you really needed to, to get your perfect joint. After all, the idea of jointing is always to remove just enough wood to create a straight, flat board edge. Removing any more than that is just a waste of wood.
Always cut with the grain of the wood and never against. Hold the stock with your left hand against the fence and push it with your right. This may take a while since you are only shaving tiny pieces. Be patient and take your time.
Depending on the price of a jointer, woodworkers and woodworking companies often consider buying it used. In most cases, smaller, lower capacity jointers are affordable to purchase new. Purchasing a lower capacity jointer new is also a good idea because, unlike industrial grade jointers, lower capacity jointers typically aren't designed to stand up to commercial level use for years on end without experiencing a drop in efficiency or dependability.
