   Hopefully, you haven't assembled the frame yet. Cutting the rabbets will be easier. One way to do this and, perhaps the easiest, is to use the table saw. First, cut a kerf along the edge of the flat side of each piece corresponding to the width of the rabbet. Then reset the saw fence and run the pieces through on edge to cut away the remainder of the material to make the rabbets resetting the blade height as needed.

   You can also use a router. You will need to make multiple passes with something like a pattern bit to get the wider width. You can also use this method if you already have the frame assembled.

   Because of the different rabbet widths, you will have a situation where the inboard edges of the rabbets will not line up at the corners of the frame when assembled. If this is important, you will need to stop the wider rabbet cuts short and do some chisel work to line them up.

   Agree with bilyo on this - only thing I might add:

   If you cut the rabbit depth to the same as the mirror thickness, it may be hard to mount unless you perhaps use adhesive caulk to "glue" it in.... Usually for 1/4" thickness (mirror or framed materials for pictures) I would make the depth 1/2" so I have room to nail small brads or framing triangles to hold it in place.

   Thanks, don't have a table saw so I will have to try the multiple pass route with a router. Agree on the depth point.

   One thing I usually forget until it’s too late. The inside surface of the rabbet ends up being visible as a reflection in the mirror.
