I made some good progress today. My design includes a removable shelf between the two sections that is also strong enough to hold up the big SB48 light, allow airflow from the bottom to the top half of the box, yet still be light proof. Its mostly ready to go now. The hangers for the shelf are in place and the shelf is cut, holes are drilled and the paint is drying. Tomorrow I put the edge trim on that will make it air and light tight and install the mylar. This should go fairly fast and then its on to the last stage when I hang the lights and test the airflow and temperature control. I will send some pictures tomorrow after I clean up a bit so you can see the shelf... its sitting on saw horses right now and not too impressive. ---Emmie
