I just got a brand new freud dado set , and i am making drawers out of poplar. the damn thing is tearing out the back side of all the finger joints. can anyone tell me why a new blade would do this? i am making half inch fingers with half in thick stock. it looks terrible, and i would not have expected this for the price i paid for the dado set. |

That is the way of dado sets it doesn’t matter how much you paid for it. You need a backer board. -- Bruce, Boise, ID |

Not sure just how you are making the cuts. Most any blade or dado stack can, and will, tear out the back side of the cut if the workpiece is not supported. For cutting finger joints most would use a jig that does several things at once. It sets the space for the first cut, and then sets the spacing for all of the subsequent cuts, and it provides a perfect backing to prevent tear out in the stock. |

You could use a backerboard. Myself I use blue tape before I cut to eliminate this problem. I have access to 2” tape free so it is never an issue how much I use, have no idea how much it costs normally. -- Live to tell the stories, they sound better that way. |
