Jointing wide boards
Due to a new project I am starting, it is necessary for me to joint a 9" board on a 6" jointer. Here's how I did it.
First, I cut the board into manageable lengths. I then removed the blade guard from the jointer, and got my push handles ready.
In order to joint wide boards, you need to joint a wide rabbet. This is done easily by running the board down the jointer making as wide a cut as you can. More than half the board width. After I ran the board down 4 times, I lowered the infeed table 1/16" and ran them down a couple more times.
I then took a 5' length of melamine coated board from an old shelving unit and ripped a 6" eide piece off it. The rabbet you just jointed will lay on top of this sled when you put it in the thickness planer.
Run the boards through the planer until the top surface is flat, take the sled away, and turn the boards over to plane the jointed side. When you have removed the rabbet, continue planing until you reach the desired thickness.
