• Dominos - Is There Side-To-Side Slop Like With Biscuits?

    From DerbyDad03@21:1/5 to All on Sun Mar 19 11:50:04 2023
    I don't know if any of you are familiar with the "Insider Carpentry" channel
    on YouTube. Spencer Lewis does carpentry for high end homes and offers
    tips on how to be efficient in an effort to make the most of your time. You know, the whole "time is money" thing.

    https://www.youtube.com/@InsiderCarpentry

    In the following video he uses both Dominos (and Lamello Clamex
    connectors) to make 10' sides for some bookcases. As far as I can
    tell, he cuts the same size mortise in both boards (~4:30) but then
    he goes on to show how he uses clamps to line up the boards so
    that the side edges are flush. (~7:33).

    So here's my question: Is there side-to-side slop in *all* Domino
    usage and Leon's method just gives you more adjustment room or is
    Spencer using oversize holes in both boards? (I've always assumed
    that the standard Domino mortise would result in tight tenon, with no movement.)

    The domino machine cuts three different width slots. All are the same thickness (to match the thickness of the selected domino tenon). The narrowist width matches the domino tenon, which provides a snug (no movement) fit when the tenon is inserted with
    glue. The remaining two widths provide side-to-side freedom to allow for aligning the two workpieces to be joined. Conventional (Festool recommended) slots are tight fit on one board, and fit with side-to-side movement in the mating board.

    So, even though Spencer (the YouTuber) was very specific with just about
    every other item/process regarding the "lengthening" of the 8' plywood
    boards, he didn't mention that he uses a "wider width" setting for his Dominos. OTOH, he uses a mallet, with significant force, to seat the Dominos (~5:45) which leaves a casual observer like me to think that the tenon is pretty tight.

    Spencer is usually very (one might say "overly") detailed in all of his videos and I was fully expecting him to mention the setting on his Domino machine, but he never does.

    He used the narrow/exact fit setting for all 4 mortises. I could see the
    dial on the Dominio. That said he did use the short Bessey to even up
    the sides. If you let the Domino move left or right during the plunge
    cut, the slot will be wider. This is likely what happened and or his
    lines, for manually places mortises, were not properly aligned. Poplar
    is soft and the mortises can be elongated by misfit alignment cuts while
    simply closing the joint. IE forcing the joint to close, as he did. It
    is better to use an elongated mortise for the mating side so that you
    can align the joint if needed. In harder woods he may not have been
    able to close the joint.

    With Spencer’s quest for “efficiency” in all his processes, I’m sure that he
    would argue that aligning the joint with a clamp is more efficient than changing the setting. Unless he’s hiding something (he usually admits his errors) he did managed to get 20 bookcase sides built using the single setting.

    (I’m speaking for him, not disagreeing with you.)

    Is it just as hard to get the dominos in (multiple mallet blows) when the wider setting is used?

    Inderstood, and I very often use a clamp to align top and bottom rails
    with stiles on frames. But letting the Domino move a touch this way or
    that way is something that can happen with out you noticing. If the
    holes were perfectly cut, not a touch wider from the Domino shifting
    1/16th of an inch left or right there would be no need for alignment
    with a clamp. But again there could alternatively have been another
    error of of aligning the Domino with the pencil marks. Not admitting to
    making an error does not mean that he saw an error and did not mention
    it. It is likely that he did not know how or when the error occurred. I
    pretty munch never use the alignment pins on the Domino, I use the
    visual alignment method as he appears to have done, the reason explained
    below.

    And a little more on that. 15 years ago early in my ownership of my
    Domino I returned the unit to Festool for adjusting the indexing pins.
    The left pin was not the same distance away from the outer path of the
    cutter as the right pin. Basically that resulted in the mating pieces
    being slightly our of registration to each other, left and right.
    Festool indicated to me that over time as things wear that the path, not
    the indexing pins, could go a touch off center to cut slightly left or
    right of center. That is when they advised for me to use the tight fit
    and the loose fit method of joining pieces. And that has worked out well.

    Is it just as hard to get the dominos in (multiple mallet blows) when the wider
    setting is used?

    When dry fitting NO other than the friction of the fit. The tops and
    bottoms of the Domino's still touch the wood whether the sides do or not.

    But introduce glue and that can change as the glue tack begins
    immediately. On the cabinets that I am building the face frame stiles
    have 4 rails between them. So that is 4 exact fit mortises in the ends
    of the rails and 4 elongated mortises in the stiles. Aligning all of
    that at the same time as the first top or bottom rail domino is placed
    the glue begins to grab immediately, so to speak, while I futz with each
    of the remaining rail/domino's. Still not "stuck" as the glue has not
    cured but the tack and the wood swelling a touch can cause more effort
    to close the joint. I tap with a soft face hammer to get the joints to
    close most of the way but a clamp is necessary to close the joint.

    If I used exact fit mortises on both sides of the joint in these
    instances it would have been way more difficult. Remember also that
    exact fit Domino's, when being glued in place, are going into an air
    tight mortise. I always have to hammer the Domino in on an exact fit
    mortise when glue is applied. The elongated single mating mortise, if
    put together immediately, is a quick slip fit.
