Constructing the SASS
1/8 " sheet plexiglass© or lexan©
1/4 inch plywood
3/4 x 2" pine (2 each 5 inches long)
sheet styrofoam available as panel insulation ( I used 3/4" sheets)
1/4" plastic foam. (I used foam that was used to pack my computer motherboard when it was shipped )
polyester fiber batting
vinyl upholstery fabric
Hole grommets ( I used DigikeyRP454-ND)
assorted screws and bolts
Cut out two side panels from 1/4" plywood
Cut out two wing panels from 1/8" plexiglass or lexan.
Construct the carcass by nailing and gluing the two plywood side panel with
the 5" pine blocks.
Fill the cavity with the panel insulation
Pad the outside with the batting and hot glue the upholstery fabric giving the SASS a rounded contour simulating a head.
Glue plastic foam to the side of the "ears" to prevent sound reflection
I spray painted the inside of the ears with black paint and fitted a piece of fabric-covered plywood as a back to the SASS
