Wall Mounted Light Box

Step 4 Router the ends of the box strips

i'm not sure why i do this. i think it looks nice, i guess. and it helps to keep the whole thing square during the building process. it may take away from the overall strength of the box. skip this step of you don't have access to a router, but be warned that it will throw off all of the measurement that i'm providing. but you didn't really want to build a light box the exact same size as mine, right?

i routed a chunk about 5/16" tall and 1/2" deep from the 23 3/8" side panels of the box.

from the top and the bottom strips, i routed a chunk about 1/16" tall and 1/2" deep.

but measuring router stuff is pretty much impossible in my opinion and it always seems like a crap shoot. this is what my edges ended up looking like. your milage may vary, but keep in mind again that the amount of your router effects all of the measurements on this bad boy.
