Domino connectors

[Gavin B]

Hi all! Looking at using domino connectors to attach the breadboard ends to a table I’m making. Wondering if anyone knows how you allow for the moment of the table , so it doesn’t split, but still hold the end on form. Thanks so much for any help!

I have done this several times using 14mm Dominos. I viewed a number of YouTube videos and followed their techniques. I also practiced on scrap several times before attacking my table.

I recommend watching a number of videos and then deciding what technique appeals to you. The procedure is difficult to describe, but intuitive once viewed.

Hi [member=76648]Gavin B[/member]

Whatever plan you come up with one side of the domino joint has to be elongated to allow for movement. If it is a domino connector then make sure that all elements of the connector that will be required to move have space to do so.

For the DF700 system the expanding anchor should be the fixed element and the allowance for movement incorporated into the other side of the joint. This will require both widening of the domino slot and the provision for the transverse anchor.

I would strongly recommend having a practice go with some odd ends of wood. When that joint is made hold one half firmly in a vice and try bashing the part that is not clamped several times from both directions to simulate expansion and contraction. This way you can judge whether the breadboard end will remain in contact with the long parts.

Google "breadboard table with dominos" and there are a bunch of videos on breadboard ends using Dominos.

When the table wood moves over time, you will see a difference between the breadboard end width and the table width. The breadboard end cannot stop the table width from changing, it just accommodates the movement without fracturing the table wood.

At least, that is the theory.

Good luck and please practice on scrap. Let us know how the table turns out.

I thought the OP was wanting to use the domino 'connecters', not the dominos only.  I may be wrong though.  There are plenty of videos for dominos and breadboards but I had not seen any that used the connecters instead.

If [member=76648]Gavin B[/member] wanted to use just normal dominoes then it would simplify things enormously...

One side of the domino joint should be in the narrow setting and the domino glues and the other side should be a wider setting. Then, on that wider setting side, make an elongated slot in the underside of the table to take a screw which is screwed into the domino. The exception is the middle domino which should be in narrow slots on both side of the joint and glued in place.

I agree with Peter...using just Dominos would be my choice here and it's easier. Breadboard ends do not need to be removable. Pin/glue the center Domino and let the others have some float with the width of the tabletop that's cross grain to the breadboard end. One could also create a wide "shop made Domino" for the fixed center position and normal Dominos towards the ends as a variation. I'd typically use 14mm Domino stock for this kind of application, assuming the tabletop is thick enough which for my designs likely would be the case.

I made the assumption that the OP wanted to use wood tenons. It never occurred to me that using connectors would be considered. I can see how a connector might work as the center tenon, but not why it would be a first choice.

There's still a possibility that the OP meant domino tenons. We'll find out when he comes back.
