|My chaotic lab set up on the floor is seen on the photo. Audio was picked up only 0.3 m (1 ft) away to get rid of some room acoustics, and with a mattress piled up behind.||The second
was made from .7 mm iron sheet, slightly curved, with
sides folded down. The distance between languids was set at about 6 mm
at the mouth. Extends inward about 75% of the pipe depth. A narrow
handle extends to the back pipe wall where it is held by a screw.
Detail photo attached.
