   You would need to provide more construction details to answer this question. Your bottom rail seems quite thick but you don't mention what you are attaching it to. Are there legs or simply side panels? Is there going to be a reveal or is it going to be flush? A drawing could be helpful too many questions.

   A description or drawing of the joint would be helpful. The easiest way to place 2 dominoes on the same tic mark is a spacer block.

   On the original drawings, a traditional double mortise and tennon were used on the front bottom rail and leg. This got me thinking that a (stacked) domino would be approprite, or would a 10mm x 50mm hold on its own?
   Many thanks

   Those are odd plans. The rails are ⅛" narrower than the legs so there must be a reveal somewhere probably the front so be sure to account for that. Then the vertical partion is ¹/16 of an inch narrower yet for a reason I don't grasp at quick glance. Since the text blurs too much to read when I try to enlarge the image I am left scratching my head but be care to account for these discrepancies when you position your Domino. Spacer blocks probably would be the easiest way. I think I would register the Domino fence to cut the back mortise of of the face of the leg first, cutting it oversized, then use a ⅛" spacer to cut the corresponding mortise in the rail. Reset the machine to cut the standard width mortise(remember to keep the machine running) add a ½" spacer to the ⅛" and cut the front rail mortise then remove the ⅛" spacer and cut the corresponding mortise in the leg. That should leave you lined up with an ⅛" reveal between the face of the leg and the face of the rail.

   Maybe I'm misunderstanding your dilemma. Why can't you do one mortise in the rail, then flip the rail over to do the other one?

   With a member that thick the double domino would be best. Flipping can introduce errors if the parts are not all perfect. Always using the show face as the reference keeps reveals consistant.

   I guess I'm extra careful in measuring and milling, in my 40 years of woodworking I can't remember ever having that problem. :-) As for the original question and double mortise, page 14 of the manual talks a bit about it. If you haven't milled your lumber properly and you're afraid to flip it, :-) use the fence on the Domino. I also have specific size scraps that I use instead of adjusting the fence, which makes for quicker work. On a recent bed I built with 3" legs and 1" rails, with a 1/4" reveal where they join, I mortised the rails flat on the workbench, then put down a piece of 1/4" on the workbench for the Domino to sit on (not the post, just the Domino) which gave me my 1/4" reveal.

   You could type "domino joiner help" in the search box. I'm pretty sure you'll find what you need there.

   Thanks for replies. I've milled all parts the same width and will trim for reveals after I do the joinery. Funny I never thought of flipping for the double domino. Thanks for the idea!!
