Very nice idea indeed. But don't J-Disks require some sort of covering to help with the separation?
All of the ones I've seen do have some sort of covering, but then again so does the ping pong paddle... it's a layer of rubber on each side. I bought a paddle with the thickest padding. I've done some simple tests walking around from side to side while talking and it does seem to work well. I also repositioned the holders closer to the center and set it up so that the mics are now facing out away from the paddle.
Batchain, I cut off the handle, then attached the threaded part of a microphone holder to it.
