Thanks FidoJoe, and Craig....I wish I was a mastercraftsman...heck I'd be ahppy if it looked like I knew what I was doing, but truth be told, I'm wingin' alot of this....
Okay, So the last three pics were of the lightbox w/ the top facing the camera, the opening facing away from the camera, (this is to orient anyone who might be confused by rambling explanations etc), and i was in the process of filling the gap in the back for aesthetic reasons, but still wanting to have some airflow from the back of the lightbox to keep heat transfer from the lights to a minimum....
here I covered up the top pf the frame, and the unsightly dribbles of stain....notice the seam where the two pieces of plywood meet on the side....
And here is the strap/band which covers the bottom of the frame...it kinda looks from this pic like the scrap wood I have the lightbox resting on to keep it off the floor is part of this whole mess...it not, really.
