Any potential problems for using wide dominoes for breadboard ends?

[ChuckM]

Has anyone ever tried using dominoes (wide width setting, or even overlapping mortises to increase the mortise width used with shop-made wide tenons) as the joinery method to attach breadboard ends to a panel/table top? The objective is to keep the panel flat.

I plan to glue only the centre dominoes while elongating holes on the rest of dominoes before pegging.

Making them 40-60 mm wide is not a problem. But if made with DF500 breadboard tenons would be too short for my liking.
Look at the second link in the previous post. The elongated pin holes would go through the very end of the tenons (weak spot) and very close to breadboard edge.

Thanks for sharing your previous project links...I will study the information there before deciding if the dominoes are suitable for breadboard ends.

Good point on the holes being too close to the edge.

I will deepen the mortises on the breadboards with a drill bit...a technique I have used once before with good success. (I won't have enough projects to justify and use a DF700. But I have used the DF700 and frankly, could not understand how it can be used with the after-market adaptor bit on a long-term basis. The weight, control and size make the DF700 a struggle for me (small arms!) to use on small or narrow pieces.)

Here's my technique of a sliding tenon on a large headboard. The Domino tenon was sawn off flush after firing it all together. No problems after several years.
