Highlights:

Step 1: Use a Fence, and Adjust the Blade

Cover the rip fence on the table saw with a sacrificial saddle fence (Image 1).

Bring the blade up to the height of the piece on which you want to make the jointer cut (Image 2).

Step 2: Move the Sacrificial Fence and Cut

Move the sacrificial fence over so that when the cut is made, half the thickness of the blade will cut into it.

The outfeed table on a table saw may not be long enough to get a smooth jointer cut. As the front end of the board hangs over the end of the table, the back end of the board near the blade is raised. To solve this problem, add a small strip of wood to the outfeed end of the sacrificial fence. The width of the strip should be half the width of the blade, since the other half of the blade is covered by the sacrificial fence. The strip creates the offset between the infeed and outfeed tables found on a normal jointer and supports the front of the board on the outfeed table.

When building a sacrificial fence, make sure the screws used to hold it together are located well away from the blade. Also, use a countersinking bit. Use glue to attach the outfeed strip of wood.
