    Dado Depth?,, added new question???

    Ok this is for research and the comparison of other woodworkers logic.. i have made many dados, and when i first started in this hobby i would use plans given me threw a magazine which told me to do this or that.. but now after a board or two has been ran threw the saw with a dado head installed.. i have had some of my own ideas..

    so whats your most used depth of dado and why? for me on 3/4" stock it was always 3/8" deep but now i tend to go with a shallower depth of 1/4", reason being the shear strength is the same i believe in both depths and the shallower depth actually gives a stronger side piece..

    now i got a dilema,, i have a side that is 26" wide and 68" long ,, that needs 5 dados the 26" way.. i thought i could use my dado blade but my head wasnt turned on fully.. how do i support it way out in no mans land to make the first dado that is up 12" from the end of the plank????

    Larry I always go with 1/2 the thickness. I view the glued joint with the piece in place a replacing the part I took out. JMHO

    I to am of the half the thickness club. Not so much worried about the side strength as I am of the lip or to put it another way how much wood can I get under that shelf.

    I generally go with the 1/4" depth also, it has seemed to be adequate strength for what I do. I have never had an issue with that depth.

    I always use 1/2, but when I make a cabinet with one center wall and shelves on both sides, I only go 1/4 inch.

    Half the thickness is to much. On 3/4" material I try to leave 1/2" of material. Makes the math much simpler and with plywood being less than 3/4 thick your dado is less than 1/4".

    On 1/2" ply I leave 3/8" of material. Again the math is easier and it gives you more meat to nail/screw the pieces together.

    The dado should only be thought of as an alignment aid. I've built many a cabinet in my 30 plus years of wood working without dados that has stood up just fine to daily use.

    At work we use dados because for one the cnc cuts them and secondly it makes assembly of the cabinet a no brainer that a trained monkey could do.

    On 3/4" stock, I make the dado 1/4" deep. IMO this is esthetically pleasing, and adequately strong.
    If you're not part of the solution, you're part of the precipitate.
