I'm using dominoes to join the legs and stretchers of my workbench. There are two different layouts, and mirror images of them, and 4 different combinations of depths. Each joint has four mortises, 2 at normal width and 2 at wide width. A total of 96 mortises to machine. All the stock is 4x4 so you can't tell orientation at a glance like you could with rectangular pieces.
I'm fairly new to the domino and I don't want to screw this up. I know a miscut mortise can be plugged and re-machined, but would like to avoid that. I decided I wanted to mark all the mortises rough location, depth, and width, as well as indicate which sides were the reference faces. So after I made my test pieces, I sliced off a thin section of each layout, and used them to mark all the pieces parts. Of course I will use the domino built in guides when doing the machining, but at least I can easily identify the correct reference faces and settings for each mortise.
I'll be doing the machining tomorrow; we'll see if I get them all right.
First pic shows the slices I used as marking templates, second photo a few marked pieces.

edit: Forgot to mention...the mirror image pieces are easy, just flip the template around and mark from the other side.
