Thanks for the Welcome. In the video series I cover extensively how the center pivot disk works, but basically it is sandwiched between 2 .125 plates on each side of a .750 center section. The disk is about .010 smaller in diameter than the hole in the center piece and is mounted .250 below center. The center disk has a 5/8" hole in it and a slit between the pocket & that hole. The locking screw with the Delrin shoe is first tightened down Just enough to secure the mic. The disk is then rotated to the desired angle and just a little more pressure on the screw will expand the disk enough to lock it in place.
The disk is made from hot roll steel which has much more "memory" than aluminum, which, of course, would have been easier to work with, but probably wouldn't release as readily as the steel does.
I didn't put any kind of padding between the mic & the pocket but it's just static pressure and shouldn't mar the tool. The clamping shoe is Delrin so it shouldn't cause marring either. A thin piece of felt might have been a nice finishing touch though.
The attached pic is of my prototype which differs only in the center is made from 1" thick material & the know is a little different. They just happened to be what I had available at the time I built the prototype.
