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.
Feller buncher. A feller buncher is a type of harvester used in logging. It is a motorized vehicle with an attachment that can rapidly cut and gather several trees before felling them. Feller is a traditional name for someone who cuts down trees, and bunching is the skidding and assembly of two or more trees. A feller buncher performs both of these harvesting functions and consists of a standard heavy equipment base with a tree-grabbing device furnished with a chain-saw, circular saw or a shearâa pinching device designed to cut small trees off at the base.
