My new iso stand is somewhat similar only I use a bed of teeny tiny glass microspheres that are almost perfectly round. The "action" is much better with the glass microspheres, you betcha. I also use a large glass tile and springs and diamond hardness cones. Oh, my! I’d post a pic except it’s proprietary. This iso stand simulates the head of a woodpecker that can withstand shock and vibration that accompany decelerations around 1000 g whilst pecking at 20 pecks/second that would otherwise kill it. I call it the Woody the Woodpecker Stand.
