Lay the strip of 1/2-inch PVC pipe on the ground. Use a tape measure and marker to mark off every 1 1/2 inches. Make four of these marks.
Keep the tape measure in place. Mark every four inches beyond the last mark 1 1/2-inch mark. Make four more measurement marks.
Measure out 5 inches from the last 4-inch measurement mark. Make one 5-inch measurement mark.
Use a small toothed saw to cut the pipe at every mark. Mark the 5-inch piece with a "C" so that you know it is the cross piece.
Build one of the stanchions. Push two 1 1/2-inch base leg pieces into a three-way joint without threads. The base leg pieces go into the corresponding ports on the joint, leaving the stand-alone port vacant.
Place the three-way joint assembly on your work table with the vacant port facing the ceiling. Push a threaded three-way connector onto a base leg. The threaded port should point to the ceiling, and the vacant port should be resting on the table facing away from you. Place a threaded three-way joint on the other base leg in a similar manner.
Push two 4-inch pieces of PVC pipe into the vacant ports on the threaded three-way connectors. Push them into the ports facing away from your body; the ports that lack threads.
Push two threaded two-way joints onto the 4-inch riser pipes. The joint without threads goes onto the pipes. Position the threaded two-way joints so they face the ceiling, mirroring all vacant ports on the stanchion.
Screw four threaded caps onto the threaded ports facing the ceiling. The threaded ports are on the four corners of the assembly.
Wrap a rubber band around the top-right screw cap. Stabilize the band between the raised hexagonal head and two-way joint body. Stretch the band across the stanchion and stabilize it on the lower-left screw cap.
Repeat step 10 but connect the upper-left screw cap with the lower right to create a criss cross. Layer the criss cross by repeating step 10 -- alternating top-right to bottom-left and top-left to bottom right -- until there are six stacked rubber bands.
Make another stanchion. Repeat steps 5 through 12.
Connect the two stanchions with the 5-inch piece of pipe marked with a "C." The cross pipe will push into the open port on each stanchion. Position the stanchions so that they are a mirror image of each other.
Slide the microphone through the web of rubber bands. Right down the center is a diamond-shaped opening that the stem of the microphone can fit through. The microphone will be shock-mounted between the two stanchions.
Connect the cross piece to a 3/4-inch microphone clip.
