Be sure to always keep the following safety guidelines in mind when working with a woodworking jointer: Always wear eye protection. Ear protection as well. Read the owners manual. Use a push stick when necessary and never use your hands to push a tiny piece through. Never joint a piece that is less than a foot long or less than ten inches wide. Always turn off and unplug the jointer before adjusting or servicing it. Always leave safety guards place unless it is necessary for that particular task, such as rabbeting.
Originally jointers were used for the following purpose. Often woodworking projects require a flat surface that is wider than one board width. For example say you are building a table. Here you might need a width of 42 inches (about 100 cm) or more. This can be accomplished by clamping and gluing four or more boards side by side.
A wood jointer is power tool used by woodworkers to square and true boards. In other words it will make a board straight and its edges will be at perfect right angles to its top and bottom faces.
Sometimes, with curly or wavy grain structure, you will experience tear-out from the lumber edge even with sharp knives. Sometimes you can turn the board around and run it through again backwards with very shallow cuts until the edge is fully jointed and the tear-out is gone. At other times, you may have to settle for a sawn joint made on the table saw. Usually you can make fairly good glue joints this way, if you have to, but a jointed edge is always my first choice.
Start up the woodworking jointer and let it reach its full speed before jointing any wood. Never allow your body to be to the right of the cutter knives. Always remain to the left. Hold your wood against the fence firmly, using a push block whenever the stock you are using is too small so that you can keep your hands safely away from the blades.
