What is the purpose of a wood jointer?

Will a planer fix warped boards?

Who invented the jointer?

As covered in Early History of Jointers, the modern jointer was patented by Climer and Riley in 1866. Before that, many attempts were made to produce an effective machine to flatten the faces of boards. The earliest woodworking machines were sawmills that reduced a log to rough-sawn boards.

How much does a jointer take off?

Again, the maximum cut will depend on the width and density of the workpiece, but I generally don't remove more than about 1⁄8" at a time. For pieces that aren't much longer than your infeed table, hook your heeled pushblock onto the trailing end of the board.
