vibration mounts for compressor

[scott37300]

I'm working on getting my compressor all hooked up and want to get some anti vibration mounts for it. I made the metal shelf brackets, made the platform, raised the compressor up 5 feet onto it(that was fun). Hooked the electricity up, just using the breaker for the switch for now, am going to look for a disconnect switch sometime. Changed the oil, need to get a new air filter sometime. Then need to get some pipe and wor on the plumbing.

But for now I need to secure the compressor to the platform, wouldn't be pretty if 315 pounds of compressor fell 5' to the floor! The compressor doesn't "walk" around on the platform, but does have a little vibration so I would like to do something to keep them to a minimum. I was looking at mcmaster and found these, http://www.mcmaster.com/#64875k36/=9ddyna, have to click on page 1365(not sure why I can't get the link to that page to work), style 3 or 4. They are rated for 130 to 680 pounds per mount depending on the hardness of the rubber. So any of them will work, anyone have advice on what hardness of rubber to get to eliminate the most vibrations? My other thought was to just get some rubber matt to put between the compressor and platform and lag bolt the compressor to the platform. But think the mounts are my best option?

Anyone have advice or pics of how they mounted thier compressor? Here is a picture of mine so far.

I have a large upright (600+ lbs) and it's mounted on donut style cushions that I got from McMaster- but I dont' think they're on the page in your link. I'm anchored to concrete so it's different that what you're doing. What I have works fine so if the feet you have will work with donuts just get the style you like with 130 lbs capacity ea assuming 4 feet and 315 lbs. You could probably even get by with something low tech like rubber mudflap pieces with holes in them and a bolt with a locknut. Definitely use locknuts as you do not need to overtighten.

Thanks Steve, I found some that you screw to the platform and then use 3/8" bolts to bolt the compressor to the mounts. I think these will be good and only 7.50 a piece. I fixed the link in my first post to show them.

hockey pucks with large fender washers on either end.

I know hockey pucks are a popular choice but they are way too hard to effectively dampen a big compressor on a wall shelf.

something more like this maybe?

I was wondering what a good hardness/durometer for good dampening would be. Thinking I should get as soft of rubber for the weight load as possible. The one you linked to are 20 bucks a piece with shipping, the ones I linked to from mcmaster are only 7.50 a piece and a 30A durometer and rated for 210 pounds each. The hockey pucks seem ok but I would have to buy them at around 2 bucks each, think I would rather pay the extra 5 bucks a piece to get a real mount that is rated.

hockey pucks aren't going to offer any significant damping- they're way too rigid. And c'mon, for $15-30 for 4 real vibration mounts, why reinvent the wheel?

This is what I have from mcmaster. They're $7 ea now but were $4.37 when I bought them in 2003. page 1364. you don't need anything this HD, but it's what I used so I figured I'd share
