So i went in for a bit tonight and finished attaching pieces of wood to each bird head for the dowels to fit into. I also measured the box we're using for the main set and will make a plywood frame to attach to the front of the set tomorrow afternoon in the woodshop. Also, the pieces of wood we glued to the foamcore to correct the bowing last Tuesday seemed to work well and the side pieces stand on their own inside the box.
