This is quite coincidental, Gerald!!!
I am right smack in the middle of doing the same thing. LOML has hated the BR mirror since we took up residence here in this place over 25 years ago.
In talking with another great NC Woodworker (Joe Scharle) we decided that we could make a frame for my 28" x 32" mirror that would be acceptable to the LOML.
We used some 4/4 poplar glued up into 1 1/2 x 3" stock blanks and used his tablesaw cove cutting jig and a multi-bead router bit to come up with this profile. (Along with a 3/8" x 3/8" rabbet for the 1/4" mirror.)
Here is a couple of pictures of where I am at (unfinished and then 1 coat of primer and two coats of oil based white paint - Sherwin Williams Extra White.)
(This is the front of frame.)
Oh ya. We used pocket hole joinery for the frame and it is plenty STRONG!
I am hoping that the frame will be dry enough by Friday to mount the mirror.
I think that this method has been a little cheaper than buying frame stock.:dontknow::dontknow:
Let us know how you make out.
