I'm way behind on updating this build; coupled with a week vacation and a week long sinus infection progress has still been made. Since my last post I have reinforced my original layer of fiberglass by criss crossing 3/8 nylon rope along the bottom. I have been reading up a lot on fiberglassing subwoofer boxes since I am new at this and have seen people in other forums use this nylon rope over flat surfaces to make it more rigid. When the resin soaks into rope it hardens like a dowel rod. After laying all the rope I used painters tape to help hold it all down while fiberglassing
I then layed two additional layers of fiberglass mat ontop of this. This is a major PITA trying to keep all the bubbles from forming under the glass.
I was running out of light so the picture is a little dark but this is the finished product.
