The screws used to hold the enclosures off the ground were removed first. They left very damage. The light diffusing sheets ordered from Tap Plastics arrived and were cut very cleanly. The measurement for the long edge was more than necessary which was intentionally on the generous side to allow modification. The intention was to flex the plastic sheet until it fit into the channels but the length prevented that. One channeled side was removed to measure how much needed to be removed from the plastic sheets. Once the channeled piece was removed the extra length of plastic could be measured. The wood was prseed into place and the gap was measured at 0.317" (8mm)(21/64").

A potentiometer was scoped for use as a volume control. The schematic and package were drawn and it was put in the drawing. A two-terminal post was put in to give the speaker a place to connect.
