After reading Rick's post about 6in. jointers, I thought I would post a solution I heard of a few years back about jointing a board that's wider than your jointer.
First, remove the guard. I know, I cringed when I read that, too, but you need to do that when you rabbet a board on the jointer.
Depending on the size of your jointer, you can use the following process to joint a board up to half as wide as your jointer, 6in board with a 4in. jointer, 9in with a 6in. etc.
Joint the board as you normally would with one edge against the fence. I'll use a 6in. jointer as an example with a 9in. board.
After you have done that, you will have a 6in. wide smooth area (obviously, you may have to do this a few times depending on how flat the board is.) and a 3in. wide untouched part. When you get the 6in. part smooth with all fresh wood and no rough part, depending on how much you had to remove to get there, turn off the jointer. Turn the board over.
Now, use a piece of plywood that is 6in. wide and a tad more thicker than the unplaned part of the board. use either a 1/4, 3/8, or 1/2 in piece of plywood. Get some double sided carpet tape and carpet tape the piece of plywood to the smooth new wood.
Now, place the plywood side down and run the 9in. wide board through your planer. Take VERY LIGHT PASSES until you get the unjointed side flat. Then pull the carpet taped plywood of the other side and plane to the desired thickness.
I've done it quite a few times and it works great. Just be VERY CAREFUL with the guard removed on the jointer. Use your push blocks and proceed slowly. Hope this helps.
