I believe they're called anti-nodes. The points of the wave where the amplitude changes the most. Since they reverse, I don't think there's a different name for the high spot â¦ or low spot.
A jointer may also be used to flatten the face of a board, in which case the sole focus is to produce a flat surface on the face of the board and the fence is not used. This procedure is often performed prior to edge jointing so that the board has a flat reference face for subsequent operations. jointer that is used for rebating has the outside ends of its blades also sharpened and set with a small clearance from the cutter head. A jointer cannot be used to create a board of even thickness along its length.
Jointer is the machine you use for straightening lumber, called, I believe, an overhand planer in Britain. The term joiner usually refers to plate joiners or biscuit joiners. Michael R. Michael. 1  Reply. 2  Reply to Original. 3  Print this page. 4  Email this Message. 5  Permalink.
