Could use some advice on mounting a mirror in a wardrobe door. This is a ca. 1930’s piece bought for $35 from Habitat for Humanity. So far I’ve invested more in sandpaper and stripper that the item cost. But to come to the point: There was originally a mirror in the door, mounted in a rabbet. Mirror dimensions were about 12X38 in. Rabbet is 3/8 deep. How to mount a replacement mirror? There won’t be enough depth in the rabbet for both mirror and stops, so something has to go over the back (the silvered side). Should there be a backing board, e.g. 1/4 PW? Will it interact with the silver? Are there special clips to attach the board+mirror to the frame? How many should be installed? I’ve read that the rabbet should be painted black — is this so?
Thanks. Haven’t been on BT or Knots for some time — big differences in appearance.
