For centuries and centuries, wood has been considered a beautiful material, as well as being relatively easy to work with and ideal for turning into houses and furniture. Over the years, the disadvantages of dealing with wood have been overcome with various techniques and preparations. One of the difficulties of wood is that it isn’t as stable as metal or stone, and it contracts and expands under different conditions eventually creating warping.
The “starting point” of such issues with wood happens when it is cut out and dried, as wood continues to move throughout its lifespan, determined through humidity and temperature changes around its environment.
There is one “strengthening technique” which woodworkers have adopted called jointing. Proper jointing maintains tables, chairs, joined boards and frames in good condition and also adds to the aesthetic elements of such woodworking pieces.
Two of the most popular joint types are the biscuit joining system and the use of mortises. The biscuit joining system makes use of a compressed wooden biscuit which is fitted in between the two to-be-joined pieces, thus filling out respective crescent shaped holes on each piece of wood. Sheet goods like plywood and particle boards are ideal items for a biscuit joining setup. Mortises maintain the same principle as the biscuit joining setup, with the exception that, instead of biscuit shaped compressed wood, more squared pegs are utilized, which makes it ideal for more block like types of woodpieces.
A jointer facilitates fast, accurate and easy creation of joints. Most jointers are commonly mistaken to be simply biscuit jointers. They are incorrectly referred to as such, as most jointers are capable of dealing with mortise creation.
What is known as a planer, buzzer, flat top or surface planer, is actually a jointer which basically produces a flat surface on the woodpiece. The item gets its name from its primary function: making flat edges on a piece of wood prior to joining them.
A jointer is consists of two parallel tables, a movable fence normally perpendicular to the tables, and a cutter head, which is motorized. The jointer’s two tables are the in-feed and the out-feed tables. These tables are adjustable and capable of being raised or lowered. Lowering the in-feed table enables the out-feed table to determine the depth of the cut measure. Jointers are usually measured to have a 4-6 inch depth of cut. Some jointer types which are built for industrial purposes cut 8-16 inches. These jointers are larger and geared to do bigger jointing procedures.
You will find jointers in most professional woodworkers’ woodshops, for professional woodworkers work both with the demands and conditions of the element with which they deal and the demands made by their clients.
When it comes to jointers, fast, easy and accurate creation of joints is easy to attain. Whether it is a biscuit joint or a mortise, jointers make working with wood clean, simple and attractive.
