Flat-Plane With a Jointer
Using pushblocks, flat-plane the face of a piece of wood on a jointer with no trouble at all. Follow these steps for easy cutting.
You can flat-plane the face of a piece of wood on a jointer, provided the board is narrower than the jointer cutterhead. To do this safely, you will need two pushblocks to guide the board across the jointer knives. Here's how the operation is performed:
Place the board you want to flatten face side down on the infeed table. Adjust the machine to take a light cut (1/16" or less). Start the machine.
Slowly feed the board into the spinning cutterhead with pushblocks. Place the lead pushblock on top of the board, 2" to 3" back from the leading edge of the board. Place the second pushblock on the trailing end of the board.
Maintain downward pressure on the leading pushblock as the board passes over the jointer cutterhead. This holds the planed portion of the board flat to the outfeed table. Use your second or trailing pushblock to move the board forward. (See drawing below.)
We recommend that you use a thickness planer for cleaning up the rough faces if the resawn boards are 3/8?" or less in thickness. Place these resawn pieces on a 3/4"-thick backing board to provide support as they pass through the planer. Secure the wood to the backing board with double-sided tape.
