    Default Using Blind Dado Construction & Dado For Face Frames

    Hello

    Can someone tell me if its possible to make a case with 3/4 ply joined with blind dado and at the same time have a tongue on the front side edges to register into a dado run into a face frame?
    I am trying to speed up ff attachment.

    Thanks

    eCabinets can put a tenon (blind dado) on all the front edges of the cabinet components or the specific edges you want to join. If you are using sheet goods for the face frame, then it would also create the associated dado.

    I would probably tenon the left and right ends, then use regular board stock for the face frames and cut the dado manually. It should be very quick for registering and joining the face frames. A face frame of sheet goods typically uses the puzzle joint, which is also very quick to assemble. I've seen some painted MDF face frames that look pretty darn good.

    Can blind dado the front edges and the actual case construction itself?
    Blind dados in two different planes?

    Steve..
    I do this on a regular basis with both 3/4 and 1/2 case material. All our face frames are dadoed on the shaper 1/2 wide 1/4 deep. eCabs will relieve the 3/4 mtl to allow fitting into the 1/2" dado. You have to play with the dado %, but its doable. Also the blind feature keeps the dado tenon away from the FF intersect.

    Here is a screen shot of a 3/4 case (bottom) showing the intersects & dados. hard to see the relief on the front of the left side, but its there.

    Thanks for the response Gary
    Its hard to see but are your ff rabbeted or dadoed ?
    Cant use pocket screws for assembling the ff if they are rabbeted?

    They are dadoed 1/4 from the edge. If you get a system that works for you, you can also add the pocket screw slots

    I believe that Gary's responses answered this.

    A tenon is added to the front edge of the carcass on all edges including fixed shelves and partitions or as stated in the previous post you can select the carcass components individually and apply the blind dado.

    Whether it is a dado or rabbet depends upon the location of the face frame with its mating case component and whether you specify left/right or up/down for the position of the tenon.

    Thats great news
    Thanks for all your help
    I am looking at getting a shopbot alpha soon.
    I am pretty decent with ecabs ( although I wish the molding could be applied in the same way as the countertop!), I hope the link isnt too bad of a learning curve

    On the molding, try taking your upper cabinets in the cabinet editor one at a time and put crown molding on the top. Then save it that way.

    Then when you load a top cabinet into a room, the molding comes with it. It is not a perfect solution, but it is fast and easy. I have not used much light rail, but I'm sure that would work the same way.
