Stew - you will really enjoy the tool. I justified my Domino purchase when I built a crib for my daughters baby (first grandchild). Must have had close to 40 slats. Each slat had 4 mortises. Plus the headboard had my first bent lamination - attaching it was a breeze with Domino tenons. Like mentioned above, I had to make some custom stops using PVC pipe and made a custom trim stop for 1/2" thick material (that also required the Domiplate). So use your imagination!
Enjoy,
Mike
