There are two sets of pieces to make two rectangular frames, plus four
short cleats that will be glued into the corners to reinforce the corners and
space the frames. There are two blocks of 3/8 plywood that will hold 1/4-20
T-nuts for tripod mounting; one on the bottom for horizontal format and one on the
end for vertical format. The 1/4 inch plywood will form the sides and front panel.
