A few shots of the new speaker box in the coal bunker.
With that done I now needed to come up with some sort of coal load that would fit over the speaker box but still let the sound out. My first ideal was a piece of soft black foam ( stuff with lots of holes in it ) carved to shape with some coal glued to it. After spending an hour making it and a few hours waiting for glue to dry I soon realized it was not going to work as good or look as good as I hoped. After thinking about it for a little while I came up with an idea that borrows on some of my RC airplane building days.
I cut a piece of 1/16 thich plywood for model airplanes and glued some pink styrofoam to it. The plywood was cut so it fits snuggly in the coal bunker on top the speaker box. I then carved and sanded the pink foam in the shape of a coal pile. Once I had a shape I was pleased with I fiberglassed over the foam with 6 layers of 3/4 ounce glass cloth using epoxy. Once it was dry I sanded it a bit and sliced the plwood base of the foam.
The finished fiberglass coal pile.
