Step 5 Mounting the Mirrors

For the mirror support blocks, I carefully checked the 90 degree angle of my jointer and made one long piece for cutting these to length to be sure all of the mirrors would be true vertical when mounted. The small mirror mounts have both the 1" base plus a 1/4" thick extension to raise them to the necessary height. The mounting blocks are just glued to the glass side of the mirrors with a dab of Gorilla Glue. I advise drilling the mounting holes prior to attaching the mirrors, using a drill press so the holes are reasonably accurate as well. The large mirrors are mounted with the bottom edge of the mirror sitting directly on the base, and the small mirrors are mounted at the proper vertical height to be centered in the 5 inch high large mirrors.

For the mirror positioning, I printed the CAD drawing full-size, taped it to the bottom plate, and used a center punch to mark the exact locations of the mirrors. Please note that the drawing shown is my original and is a bit battered plus has some random lines that are to be ignored.
