   A sacrificial fence is used when the saw blade might or, by design, does, cut into the fence.  Most often, this is when using a dado blade.  The dado blade may be buried partially in the fence, or it may just be so close to the fence that you want to be sure that if you accidentally cause the fence to have contact, the part that's damaged is not the real fence.

   dlb, Forest Gurl is right on the money.

   Sacrifical fences also enable you to 'Shave off thin waste (More like a meat slicer (And thats no baloney.)

   In the case of the miter guage's sacrifical fence, it's placed there behind the work to suffer tear out 'Stead of the workpiece.

   Here are a couple of pictures of my sacraficial fence.  If you make one, be careful about the positioning of the attachment bolts relative to your blade location.  The second picture shows how I recessed the nuts.

   If you have cut into your sacrificial fence for dado blades, make sure you remove it for other operations. I watched a guy try to cut some 6" squares of masonite. The material slipped into the blade recess, kicked back and almost took off a couple of his fingers.

   This is what I made for our shop. I just put it on to take a picture of it. It's fastened on with a few clamps which are not shown. I can also use it for pattern sawing and specialized trimming. No pictures to explain that one or time to go into detail but definitely more advanced table saw techniques. I've seen very little written about the techniques but definitely useful in certain applications.

   Please don't think I am being sarcastic, but what was your thinking on making it so complicated?

   I use a 3/4" board bolted to the fence.

   I know you had something in mind here, and I am curious to know what it was.

   It get used for pattern cutting and a special trimming opertion. The sacraficial fence is raised up off the table depending how thick the material to be trimmed is and the edge of the fence is above the blade and aligned with the left edge of the blade. I need to have at least 3" inches clearance under the fence that's why it's so wide. I'll have to make a diagram to explain it. It was a bit more work to build but it's so fast to set up and use it was well worth it. I can take it off in 2 seconds and adjust it anywhere I want up or down in another 2 seconds.

   Are you familiar with pattern cutting and such operations?
