Cabinet doors: domino joinery stiles to rails. Which scheme to use?

[Gene Davis]

Same q posted over at the Sawmill Creek forum.  Different readership, so I am posting here also.

I'm into my next project, this one involves some small doors. Dominos will be used to join stiles to rails.

A pic is attached of one of my doors, not put together yet. I show different schemes in three of the corners, based on the domino stock I have. I also have lots of 5mm and 4mm dominos, but they seem a little small for this.

But then there is this. A whole lot of cabinet doors, in kichen cabinet sizes larger than these, get glued together with nothing more than the cope and stick detail. And for that joint, the rails have a glue surface that is 100 percent end grain.

And then also this. Some web searches for this turned up an opinion that the domino used to join parts should not be more than 1/3 the thickness of the stock, thus for my case, I should be using the 6mm domino, which only comes from Festool in 40mm length.

Back when I was joining parts like these with mortise and tenon, I would use 3/8" tenons at 3/4" long for this. The equivalent in a domino would be an 8mm at 40mm length, but I only have the 8s in 50mm.

The 6mm x 40mm configuration will be more than enough for this application.  If you need more check out;

The 6's would be correct for a 3/4" thick door.

Its a general mortise and tenon rule... mortise no more than 1/3 the thickness centered in the stock.  You can make tenons as long as you like.  You "could" through pin tenon the doors if you choose, but depending on overlay and hinge swing i doubt that is possible.  Domino tenons can be purchased or created in long lengths.

I'd use the 8mm tenons and offset them if you have to.

I made some oak doors with 19 mm x 60mm stock using your design. I cannot remember the domino size but from the photograph below it looks certain that they are 40 mm long and probably 6 mm thick. I only used one domino per joint. The doors are quite big - 940 mm high x 600 mm wide. I did have the advantage that I was using veneered MDF for the field and so it did not need to float and was glued in. If you have a floating panel then you could consider two dominos as long as they are separated by about 12 - 15 mm.

Now that I look at the picture full screen they could (just) be 8 mm dominos.

It's not really all end grain because of the shape of the cut.
