  • Question concerning Dodo’s

    Prior to today I have used a router for all my dado applications and decided it was time to experiment with cutting dados on the Table Saw. I purchased an inexpensive $50, 6” dado set from Sears. Upon inspecting the results I noticed that there was a slight disparity between the depth of cut made by the blades and the cutters. Is this indicative of the price I paid or is it a characteristic of all dado sets regardless of price? If this is considered typical, how does one go about sanding this irregularity to obtain flush results?

    Thanks

    woodslayer,
    I also have a Sears dado and would say that this might be a common thing... I asked the clerk when I bought the dado set; if it didn't produce good quality cuts if I could return it... He said they would take it back if it didn't work well... I never got around to returning it so I thought I would maybe keep it around for rough projects...

    I really wish I would have spent $34.99 more for this one instead: http://www.amazon.com/exec/obidos/tg...&s=hi&n=228013

    For removing the grooves, about all you can do is wrap sandpaper around a smaller piece of square drop off wood and staple it to the side’s, then try to sanding the marks out…

      Depending on the project or location of the dado, some people claim the grooves can be a good thing. Gives the excess glue someplace to go.

        I bought a similarly priced set from Woodcraft two years ago...it gave me perfect flat bottom grooves. It now needs sharpening and leaves little trails in the groove, but I can't see that as a problem. Unless the bottom of the groove is rounded, it'll probably be to your advantage...

        And I thought the Dodo was extinct!

          A good, or even decent dado set will leave flat bottom grooves. I bought a Freud 8" at HD for $90 and so far, it has left very clean lines. In the future, may go with somehing high end, but for now, I get clean lines.

            If the groves are a problem, take the whole set to a good sharpining shop. They can grind all the chisels to the same as the side cutters. Over the years I have had mine sharpened several times with good luck..

              Thanks for the input, I should have trusted my instincts and paid $35 more for the Freud Set. This one produces nice clean sharp corners but for applications that require a flat bottom I’ll need to put forth the extra effort and sand the bottoms flush or simply use the router

                I bought the Freud 8" stack from HD same as Mike.
                Has done an excellent job.
                One thing to not though, the guide for widths has an error in it. The undersize for 5/8" plywood says to use the same chippers and shims as for 3/4" undersize plywood. I had to mess around with it for a hour before I got it the right size.

                  Sorry, the type "DODOs" got me to thinking of dorado and much fun they are to catch. Haven't been seen within 150 miles of San Diego much for the last 4 years or so. Oh well, albacore & yellowtail are fun too.

                    I too have the Craftsman Dado set. I clean up the bottom with a good, sharp wood chisel drawn backwards thur the cut. Leaves the cut nice and flat.

                      I have the Jesada Joint Master dado set. It works great for me.
