Wall Mounted Light Box

Step 16 Mount the back piece of plex

i sandwiched my negative and some rice paper between two pieces of plex inside the frame. but i needed something to hold the second piece of plex tightly that was also easily removable in case i decided that bats give me nightmares or something.

i used 1" corner braces to accomplish this.

i measured difference from the top of the plex to the top of the pine board. i marked that measurement onto the corner brace, put it in a vice and trimmed the brace with a hacksaw. i then screwed these modified braces onto the pine frame, holding both pieces of plex tightly against the front of the frame.
