i went out to buy squash balls for new damping feet on my turntable. 3 stores and nobody had squash balls. finally i picked up a pack of wilson racquetballs. these should work fine, yes? also, any tips on cutting them cleanly? and, do i install them U (roundside down) or ∩ (roundside up)?

They should work fine, yes.

Tips: use a sharp exacto knife blade, do not cut against your thumb.

thanks, peter.

do you know which direction is best for installation (see above)?

I've always wondered how the more economical methods of vibration dampening (raquet balls, cork, etc...) would stack up against the pricier solutions...

redshifter, you should put your balls in a vice to keep them stable before cutting them in half

edit: I'd put them in the ∩ position, but that's just me. It seems like an easier way to install and position them too, unless you have the means to attach the ball to your amp/source in the U position.

well, i was going to use the budget modder's secret weapon, sticky-tack. so either way would work fine. is one way more efficient for damping vibration than the other?

The only reason I'd imagine the U orientation might be better is because there is less surface area of the raquet balls touching the table. How that translates to better dampening is beyond me, because either way, you're still using a raquet ball

ok, that makes sense. thanks, i'm going to cut them now.

I bought these at TTVJ for $19.95 plus S&H. Is anyone else using them?

 

[Thaddy]

I think I've seen those in BHD's pictures before, but I could be wrong. I'll bet you could make something like that really easy with some cork drink coasters and rubber from a, well...you know...something rubber

edit: I got it! Ikea sells cork heat pads (to put under hot serving dishes etc); stick some rubber pads underneath like the kind that come on the Gilmore Lite's and voila, home made vibration dampening.

No, I personally am not...however, I recall seeing on at least one rig in the "post your headphone rig" thread having them. How do they compliment your system and what are you using them with, your source?

 

[redshifter]

okay, cutting the balls was no problem and installation was a snap. the tt has substantial tight spring to the base now. even tapping on the table causes no noise. after a few minor calibrations i'm spinning jamiroquai "dynomite" now and the bass sounds much more under control.

oh yeah, and i have one ball left to bounce off the wall. hurray!

I don't think it matters. Whatever justification you use for putting the cut part against the player and the ball part against the table can be reversed. So I'd say whichever was easier. For example -- if you had screw-holes in the bottom of your CD player, you could drill holes in the bottom of the balls -- in that case, I would put them cut side down.

Racketballs vs. vibration isolation pads

I suppose the choice is dependent on what you are looking at dampening.

As an example, my CDP is always benefiting from dampening. Regardless of table type, placing halved squash ball underneath all feet focuses the sound and the resolution increases. I place them in the U config, because I like to have as large dampening surface as possible on the CDP. If I thought other equipment negatively influenced the CDP, I would turn them ∩ in order to dampen the minute vibrations of the shelf.

Perhaps it doesn't matter really.

There's something here that doesn't quite add up...
