An auxiliary fence is a must-have if you’re cutting rabbets or thin strips on a table saw. When I built this one, I intended to use it to protect my rip fence during those types of cuts. But after making some improvements to the basic fence, I decided to make it a permanent fixture.
The fence starts out with a wide piece of plywood to support a workpiece standing on edge. Then I added a rabbet on the lower edge to trap thin stock.
A length of T-track sits in a groove to hold a featherboard. Finally, I attached the fence to a clamping board with screws. Special clamps secure the fence to the rip fence on the table saw.
