Topic tags/keywords: table saw auxiliary fence jig question

Whether I’m watching armature wood videos on YouTube or a woodworking show on cable, I see people use an auxiliary fence either permanently or clamped to the already existing fence on the table saw; why would another fence be needed? Sometimes the fence might be a jig; but mostly its just another fence. Also if I choose to use one, I’m assuming the face should be smooth and should I connect it permanently to the existing fence?

I know of only three occasions to use an auxiliary fence: (1)using a part of a dado blade and there is need to bury the rest in the fence (because you are cutting a dado on the very edge or very end of a board); (2)Cutting a bevel on a tall board or (3) using a accessory, such as cutting a tenon using a tenoning jig or cutting spline keyways in a box. There may be others, but I can’t actually think of a reason to leave an auxiliary fence mounted when it isn’t getting used.

I have a shop fox aluma classic fence which is aluminum on the outside. I have never used an auxiliary fence, but it has t slots so that you could if you wanted to. The reasons I know of are that the phenolic ones have less friction and allow the material to slide along it easily. When it wears out you can just replace it. If you accidentally touch the blade with it, it will be more forgiving than the metal touching. A reason for clamping one on temporarily would be for a sacrificial fence for rabbeting. Is this what you have seen?

They are used with Dado blades to make Rabbits, Also to make the fence higher for some operations. Usually they are removable and only used when you are performing operations where they are useful.

Check out this link for some examples….

An auxiliary fence’s main purpose is to protect the normal fence from accidental saw cuts.
