Can you elaborate on this a bit?

Okay I have the jig clamped to a board here. I use a bit with a 3/4” diameter. If I run it down the length of this jig it will cut a 3/4” dado. So to make the jig I glued a piece of 1/4” plywood onto a wider piece of 1/4” plywood. Then I used a 3/4” router bit to cut through the wider piece by running it against the glued on upper piece.

So wherever I clamp this jig is exactly where my 3/4” dado will go

Here is the circular saw jig that is made and used the same way

Did I explain it well?

Jumping in here a little late. Your jig works great if the bit is the exact width you need for the dado.

The OP's jig, while more complicated, works for any width as long as the bit is between 50% and 100% the size of the dado width.

They're both great, but they aren't 1:1 comparable. I much prefer your version for edge rabbets, and I prefer OPs version for middle of the board dados.

Yes, thanks! I have clamped one piece to guide my router before, but using two would be much easier since it eliminates the need to measure the offset to the “far” stop every time. Clever!
