Isolation platforms, or home made sushi and a game of racquetball?

Just got my Amazon order. Picked up some nice some cans of Even better would have been "half inflated" scooter iner tubes under the bread board/s. Thinner rubber and air as the isolator. https://www.walmart.com/search/?query=scooter%20inner%20tubes Cheers George |
georgehifi, I tried the inner tube thing back in the 90s. I found it just about impossible to balance components where the center of mass was significantly off center. The Raquetteballs do have thicker rubber, but it's still the air inside the ball that provides the spring. And it's much easier to level a component with the center of mass was off center of the component. |

Very easy, you need to "think out of the square", you buy an inner tube that is smaller, 2/3rd’s the size of the plinth it’s under and locate it more to be under the heavier section of the load. Inner tube is far better at isolating than thick rubber balls. Cheers George |
The trick is getting 6", 8" and 12" inner tubes and choosing the one that best fits the size and weight distribution of the component. Fill with 3-5 PSI and balance the component on the tube. I even went so far as to fill a 6" inner tube with 90 weight oil and that was trans-formative. However, I was concerned that over time the oil would degrade/soften the rubber and I would have a huge mess on my hands at some point. Now that I think about it, I wonder if water in the inner tube would be a suitable replacement?? |
