The top platform interior with all support studs in place. The frame only contained a few support studs when it was moved into place over the bottom platform, so it would be easier to move. The additional studs were added after it was in place. The studs are approximately 16" apart, except for the one at the end which is set to support the edge of two plywood pieces where they come together.

The right half of the top platform filled with sand. The top platform has been filled with 420 pounds of general purpose sand. The sand will add mass to the platform to reduce the risk of movement, and also absorb sound energy so there is no echo inside due to people walking or the audio.

A close-up of the 1/2" rounded lip. The top platform has a 1/2" rounded lip running along the entire frame. This will blunt any feet or legs that bump into it, and overhang the rope lighting.

Interior view of one of the steps. Each step is half the height of the riser and constructed in the same manner. The cavity will be filled with sand.
2004.12.08
Both steps filled with general-purpose sand. Each step has about 30 pounds of sand in it. This will help keep the steps from moving around when touched, or from resonating to the audio.

The compelted step frame. The 1/2" plywood has been screwed to the top, and the 1/2" semi-circle lip has been nailed to protect shins and feet.

The completed riser with rope lighting attached. The rope lighting was purchased from Home Depot in a 24' length (not Christmas rope lighting) and attached with clips and #4 x 3/4" screws. It is routed under the front row carpet with a wire protector strip, and plugged into a portable dimmer set at half value.
