After having the dimensions planned I started cutting the bed frames into 63" long pieces. With that length it will allow 1" of space between the mirrors (I forgot to take into account the thickness of the angle iron itself and therefore lost 3/4" of space between the outermost mirrors and the second outermost. I later fixed this by giving a 1/2" of space to the outermost and 3/4" to the next outermost. If anything it will just give it an interesting look in the end.) I chose to make a notch and cope joint on the corners and lap joints for all the cross beams of the frames. All of the cutting was done with an angle grinder by hand.
