Intersecting Dominoes?
« on: April 15, 2019, 04:46 PM »
I'm working on building our daughter a toddler bed and currently putting together the head board. This is my first project using Domino joinery and one thing I didn't take into account is the mounting of the caps to the head and foot boards and where the domino would go in relation to the ones that are holding the top rail in place. Is it an issue to cut partially into another Domino? Even at a 12mm plunge, it would just barely cut into the top of the tenon in the second picture that is on the right (it is sitting there to show the alignment, but it is plunged in 25mm on both the leg and rail). The top cap (bottom apparent) is only going to be plunged 12mm due to thickness of the wood.

It should be fine.  If worried you could just use a smaller domino size, as it appears to just be used for alignment and not strength and support.

Correct. I planned to actually use one more from the top rail into the cap, but could do two instead of one and skip the ones in the legs completely. The only sizes I have on hand are 10x50 and 4x20.

In cases where my Domino tenons intersect, I miter the tenons. Seems to work.

I have done this plenty of times before without it being an issue.  You probably know this already, but obviously you will want to give the first joint time to try before plunging the mortises for the cap.  I would wait at least 48 hours.  I have found glue still wet inside a domino mortise after having to cut into it (like for the operation you describe) even a full day later.
