Using Dominos for 45 Deg Mitered Corner on 3/4 Ply?

[Just F Me]

Hello,

I don't have a domino yet...hoping Santa will leave one under the tree for me this year, however, I have been bad with all the purchases I've made this year so it's going to be a long shot.  None the less...I had a question about if the Domino will work for this application.

I'm making a "lid" for a box.  The lid will be made of 3/4" baltic birch plywood.  I want to see if using a domino will work when connecting two ends that are at a 45 degree miter will work?  A picture is worth more than I can describe so please see the attached screen shot...it looks like it MIGHT work, but it's gonna be really tight.  The red piece is the domino at 5x19x30

A 5 will work if you're really careful. Use a 4.

Oops

Just make 4 symmetrical "enhancements" and it'll look like fancy joinery.

It's the top to my girlfriend's dresser.

I didn't even know a 4mm tenon was sold.  THANKS

If you're careful I think you can even use 4mm dominos on 1/2" ply, but you need to rest a piece of 1/4" on top as you cut the mortises to shift the centreline up.
