Buy a heavy wood cutting block then pick the sorbothane hemispheres and give McMaster-Carr a call...

Or you use two wooden blocks with an inner tube (air bladder) between

Just put half tennis balls under things if you want them isolated. As I've said many times, my university's physics department uses those on instruments substantially more delicate and sensitive than audio equipment, and they have all the money in the world to invest in magical feet and wood blocks with logos burned on them.

I just use left over granite and slate tiles from when I finished my basement, but I like the half tennis ball suggestion better.

I have always had a tough one figuring out whether it should be:

Tennis Balls
Squash
Racket
Prarie Oysters?

I personally use single dot Squash, as they are of a small profile, but I've heard used in conjunction to a proper "Granite" isolation board, is the ultimate... and better to have the unit, then put on a stand drilled into the cement of the foundatin of your house...

You can be as excessive as you want!

That's a good idea! I should try that.

Most audiophiles would probably shun it though, saying the aesthetics detract from their listening experience.

"Wonder Balls" --- sounds like a new product for Machina Dynamica.

I am not a fan of using fuzzy tennis balls, and would rather something with tackyness yet supple such as a racketball or squash ball

I'm serious, I use mine with my isolation tray

If I remember correctly, squash balls are little rocks. I'd think you need something softer like a racket ball. It's been over 30 years so, I can be miss remembering.

What do you use to cut them?

I had planned on building something similar to this:

Magnets would cost less than $10. But I don't have the tools to make the base.
(btw, I think that company charges over $300 for that!)

You'd be surprised... it's not that squash balls are "rock hard" they have little air compression, resulting in the dampened bounce you get
I picked out some Wilson I think which happened to be the softest ones in double yellow dot

You'd be surpised how easy they cut with a nice sharp pair of henkle siccors
Just line up the seam and cut down it in half

some people go far harder than I

Squash balls also work very well to use as a plug for the bathtub. This is especially true if you are waiting for a hurricane to come through and you want to keep the bathtub full of water in case of emergency.

I had never thought of using them for an anti-vibration device! Thanks for the idea.

I've seen bamboo cutting boards at walmart and wagmens for around $25.

I use a small sized childs bicycle inner tube. Tried using air, didn't like the "bouncy" effect. I switched to fluid in the tube, with much better results. I use the "green leak fix goop stuff" (name escapes me) avaliable for bicycle tubes (also eliminates concerns about leaks). It's viscous enough to provide nice dampening, and cheap and easy to find. Works great under my turntable.
