Here is a COOL router dado jig.
This little jig will do a great job of cutting dados in sides for shelves… etc.
Most dados are not easily cut using a router table fence… rabbets are another story, going the Long direction… where you line it up as if you were using a table saw… you have a fence… you have a bit…
Are these for your shelves? Dadoing sides for the shelves?
Sounds like you need a story stick which was made from the Plans…
To be sure each side lines up with the other, it may work out to put the sides together, side by side, and cut the dados for both sides at the same time (setup).
Are you talking about a possible Stopped dado so the groove is not shown from the front?
I’m shooting in the dark… I’m not sure what you want to do…
Hope this helps…
What are you really talking about?
