Jointer plane
Template:Short description Template:ForTemplate:Infobox toolThe jointer plane, also known as the try plane or trying plane, is a type of hand plane used in woodworking to straighten the edges of boards in the process known as jointing, and to flatten the faces of larger boards.<ref name=":0" /> Its long length is designed to 'ride over' the undulations of an uneven surface, skimming off the peaks, gradually creating a flatter surface. In thicknessing or preparing rough stock, the jointer plane is usually preceded by the fore plane or jack plane and followed by the smoothing plane.<ref name=":0">Schwarz, Christopher.

Jointer planes are typically Template:Convert long, and are the longest hand planes commonly used.<ref name=":0" /> Under the Stanley Bailey numbering system, #7 and #8 planes are jointer planes.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>
The use of the name jointer plane dates back to at least the 17th century, referring to the process of readying the edges of boards for jointing.<ref>Template:Cite book</ref> The terms try plane, trying plane, and trueing plane have been in use since at least the 19th century.<ref name=":1" />
As with other hand planes, jointer planes were originally made with wooden bodies. But, since the development of the metal-bodied hand plane at the end of the 19th century, wooden-bodied jointers have been largely superseded. Metal-bodied planes are heavier, which is particularly noticeable for planes as large as jointers. This can make metal-bodied jointers more tiring to use for extended periods of time.<ref>Template:Cite book</ref>
