Isolation Rubber / Anti-Vibration Pads, Etc - What and Where to Source?

msg
msg Posts: 10,020
Still trying to settle on a system setup, but been in desperate need of a rack/organization.

In the meantime, I'm just using some adjustable industrial wire shelving.
Most of the gear is on individual shelves, on top of pieces of MDF of approx 18"x17".
Between the MDF and wire shelves, I've got little pieces of acoustic mastic. This stuff's really thin though, about 3/32", and for now is just serving more to keep MDF in place.

I'd like to source some rubber isolation disks or anti-vibration pads to use between the shelves and MDF until I get situated and get a proper rack together. I think I'd like to keep the isolation rubber to between 1/8" to 1/4". Thinking four points, like now.

Any ideas, or better suggestions to accomplish what I'm trying to do?

    Dynamat is a sound deadener although a nine sheet pack (18" x 32") is pricey. You can buy it in smaller sizes and amounts. It's .067" thick.

    Look for Sorbothane sheets, usually 1/8" to 1/2" thick.

    Music Direct has a page of vibration control products. Vibrapods are supplied in various weight capacities to be used under gear, 9/16" tall though. They sell some 3M damping sheets, thin at 15/1000ths thick.

    I use both of the above linked products with great results. I can't honestly say one is better than the other. They both work well for the price.

    Edit...the sorbothane balls WILL leave marks on your equipment so wrap them in clear plastic before using them.

    Actually, use small squares of wax paper. It is much easier to remove from the sorbothane feet when you want to move stuff.

    thanks guys, I'll have a look at some of these things.

    I have some of those little feet from HD from another project - if it's the same ones, they seem kind of stiff? I was thinking I should be using something a little squishier and vibration absorbent?

    SC - thanks, yes. the stuff I'm using is similar to Dynamat. I bought it in bulk several years ago from McMaster for lining the doors and cabin of a vehicle I was working on. It works great as deadening, but isn't as pliable or squishy as Dynamat, so Dynamat would probably work better. I think I think sticks better, too.

    I do like the Sorbothane sheet idea. Those offerings may be the ticket.

    I think I can use those pods in various other projects. I need to replace some feet that have gone sticky on another piece of equipment.

    How does Sorbothane hold up to heat? Is this how it weeps/stains? Or is it just one of those rubber products that always seems slick/wet in general?

    Sorbothane - I just looked this up. it's used in insoles, too?!? so I could just go buy some Dr. Scholl's?

    I think some of those feet leave marks so be careful with it. Use wax paper or just paper to buffer between your equipment and those feet.

    Isn't the whole idea here to soak up the vibration and not transfer it?

    Vibrapods and Sorbothane will definitely stain whatever they come in contact with. They also have weight limits.

    Look into closed cell foam rubber gasket material in the thickness desired.

    Rubber is 4 to 6 times denser than cork so in my mind it would be a better iso pad

    I believe that but the point is most of those Home Depot rubber feet are more than likely denser than cork

    Those .29 cent ISO pads with cork and rubber are made for HVAC and washing machines
    Going to be hard to beat the value and isolation

    what does this mean, exactly?
    what numbers do we look for for absorption? this is isolation, correct?

    side question - this has me thinking about speaker spikes and pads, coupling/dcoupling; isn't this kind of similar? when we say isolate, what are we actually talking about? removal of outside vibration effect in this case.

    If you decide to got the Dynamatt route here's what I did. Being a man of no means and I did check out some of the squares at IEE near me I said f to that (way to expensive ) and asked who else besides speaker modders use the stuff. Well it turns out most audio car installation places use it to deaden trunks, doors and floors. I went to one close by me and ask 1st do they use the sh&t and then when the answer was yes I asked if they had scraps around and again it was yes and they gave enough to do about 6 pairs of 2Bs some in nice full slabs Notice on the pic the passives were not fully covered, that I rectified and all now are7nb1swv7nr03.jpg
    . I did offer coffee money but they would not even take that. I did not use it for feet or interior walls of sources just my speaker baskets w/ fantastic results which all here can atest to. Good luck it's an easy mod. Oh on my sig you will notice Black-Hole-5 that was a C/L buy for $12 for a full sheet and some scraps as well. That stuff works as advertized.

    Not to drone on but for the feet of most of my gear I bought from the $ store cork coasters full sets and of course since they were red I repainted them my world famous HD flat black. I try to repurpose anything I can to avoid paying top dollar prices. Speaker cable and i/c cords I've learned do make a difference to a point and do not skimp there.
