A thickness planer is a woodworking machine to trim boards to a consistent thickness throughout their length and flat on both surfaces. It is different from a surface planer, or jointer, where the cutter head is set into the bed surface. A surface planer has slight advantages for producing the first flat surface and may be able to do so in a ...
Craftsman No. 5 jack plane A hand plane in use. A hand plane is a tool for shaping wood using muscle power to force the cutting blade over the wood surface. Some rotary power planers are motorized power tools used for the same types of larger tasks, but are unsuitable for fine-scale planing, where a miniature hand plane is used.
A jointer cannot be used to create a board of even thickness along its length. For this task, after jointing one face, a thickness planer is used. Thickness planers and jointers are often combined into one machine, with the work piece passing underneath the same rotating blade for thicknessing, but in the opposite direction.
The term planer may refer to several types of carpentry tools, woodworking machines or metalworking machine tools. Plane (tool), a hand tool used to produce flat surfaces by shaving the surface of the wood; Thickness planer (North America) or thicknesser (UK and Australia), a woodworking machine for making boards of even thickness
Thickness planer A thickness planer is used to smooth the surface of a board and make it the exact thickness across the entire board. [20] Jointer Powermatic jointer for woodworking. A jointer is used to produce a flat surface along a board's length and to create a square (or 90°) edge between two adjoining surfaces. [20] Band saw Plug-in band ...
The comptometer-type calculator was the first machine to receive an all-electronic calculator engine in 1961 (the ANITA mark VII released by Sumlock comptometer of the UK). In 1890 W. T. Odhner got the rights to manufacture his calculator back from Königsberger & C , which had held them since it was first patented in 1878, but had not really ...
The sizes of network components can be more readily modified and recalculated on a computer than through a manual process. The 2013 NFPA 13 handbook includes a supplement which describes some of the application theory and processes applied when performing hydraulic calculations.
