| Jointer planers are essential for any wood worker. They are the only tool that
can be used to mill rough stock four square and clean
up a sawn edge.
A jointer works by planing a small amount (1/32" to
1/16") of wood from one face or edge. Consisting
of an infeed and outfeed table a jointer uses a series
of cutting knives mounted onto a cylinder to remove wood.
The infeed table is set for the depth of the cut by being
lowered in relation to the cutting knives and the outfeed
table.
Jointers are classified by the width of their cutting
knives. A 6" jointer has cutting knives 6" long
and that is the maximum width of wood they will accept.
