One microphone stand attachment with nut & bolt ($1)
One 1/2-inch male threaded microphone rod ($1).
One fleece pony saddlepad ($10 or so on eBay)
Two microphone mounts (as shipped with microphones).
The idea was to make an inexpensive but very effective Jecklin Disk
for recording. This disk creates an ideal acoustic separation without
the color introduced by other methods of stereo recording with natural
placement. I have used this disk with the excellent Studio Projects C4
Trace a 12-inch (300mm) circle on the Plexiglas and cut the circle carefully with a jigsaw.
Drill a small hole that fits the microphone stand attachment
at 6 o'clock. Drill carefully; these plastics work like wood, but crack
Drill a larger hole that fits the male threaded rod approximately 1.5 inches (40mm) in diameter at 9 o'clock.
Insert the male threaded rod through the hole, and tighten one
microphone mount to each side, lining them up. (You may need to add
knurled nuts used to tighten microphone clamps.)
Slip the microphone stand attachment over the small hole in
the Plexiglas and tighten the nut & bolt to hold it in place (see
Cut one side of the fleece pony saddlepad so it forms a glove. Remove any stitching holding the center together.
Pull the glove over the Plexiglas disk, and make slits so the microphone mounts just slide through.
Attach the disk to a microphone stand and install the
microphone clamps and shock mounts. The disk is strong, but be careful
not to stress the point where it fits to the stand.
Insert the microphones with omni capsules, and place them 6.5
inches (165mm) apart, with the angle adjusted to capture greatest
high-frequency information (on-axis).
Loop the cords and attach them to the stand so they do not create pressure on the disk.
