A while back I began using a DW500 for loose tenon joinery. That is, requiring mortices wider than the standard dominos. Looking for a way to mark these accurately, I used this little marker to build 10mm wide mortices for a bed rail ...
Marke the one side, then the other, and clean up the centre ...
Marking accurately is even more important when you make through mortices, which are routed from each side, and especially when in curved chair legs ...
I came up with a new marker, which is much easier to use. This is simply a clear saddle square ...
This will do 6mm, 8mm and 10mm mortices.
Note that a 6mm domino is 20mm wide, the 8mm is 22mm wide, and the 10mm is 24mm wide. The centre marks the spot.
As we know, the mid point of a Domino mortice is aligned so ...
Start by marking the outer boundaries of the mortice ...
Set the left side of the marker on the left end of the mortice (A) and then mark the centre of the domino cut (B).
Repeat at the other end ...
Now domino the mortice ...

Re: The Domino as a morticer
#2That is cool. I almost bought one on the weekend, until I realized I would need 500 dollars worth of dominoes in a systainer box, with extra bits. That alone is more than I have paid for biscuit joiner and biscuits over 30 years. Cost isn't really the problem. I'm too old to get that much use out of it. Nice thing about biscuits or dominos is that you can 3D print so many cleaver add-on, and use the tool in unanticipated ways.

#3Hi Tam
I have just received a set of these bits, which are profiled ...

I have been making my own to custom widths with a round over bit on the router table, and shall continue to do so for though tenons. The profiled bits will be great for loose tenons.
