Hello!
I moved my Lot-O into my basement and for the most part it’s quiet enough.
I have it glued to a cement patio tile. That’s on top of two pieces of carpet. That’s on top of two cinder blocks and that is sitting on a poured cement floor.
I’d like to get this a little softer on the vibrations. Any ideas?
Wonder board? More cinder blocks?

I have a garden kneeling pad or similar under mine. My Lot-O is screwed to a small board & that's glued to a cinder block, which sits on the pad. Lynn

If whatever you use to reduce the vibrations would that suck up the vibration effect in the lot-o barrel? Has anyone ever run a vibration analysis on this concept? Just sayin' Cheers, johnw

I seen this thread and had to Laugh Since I have started rolling stones in my Lap Shop you can hear the (2) LOT O's that I have running humming away outside in the Yard Both Lot O's are attached to a cement Block and are rubber mounted to a wooden bench that is screwed to the wall. There is quite a Harmonic Vibration Happening no doubt it will drive the MOLES AWAY!

Just sayin' Cheers, johnw Brother John, I can Guarantee that anything you do to absorb the Vibrations besides jacking with the spring steel that floats the Lot O will not effect the Lot O's Performance as long as its done underneath the particle board the Lot O is Screwed to. Below you can see some pictures of my LOT O. TOM STOCKWELL the Owner of Belt Inc. Who Manufactures The Lot O has seen my pictures and he commended me on my Lot O and says they are Text Book Installation. I had a busted frame and Had it replaced under Warranty was why I contacted him.

Nice solar panels too- yours are actually louder than mine but since yours are not in the main house it doesn't seem to be an issue I got a few paver pads at Home Depot that I will put under my blocks- hoping that will help

Hello lancemountain,.....I would like to offer my rendition of what I have done to reduce the noise of vibration. My set-up is in my garage in an enclosed area so its important to keep the noise down since the area backs up to the kitchen and the den. My computer set-up is in the den next to the work shop wall and the only thing I can hear faintly is the sound of the 65T tumbling the Big Crazies and the Bahia agates. The entire assembly shown below weights in at 40 pounds. The big blocks recommended by Lot-O weigh 30 pounds by itself without fill. I used a standard block from Home Depot and two 7/16-14x2-1/2 cap screws to secure the base of the Lot-O to the block. You will need a cinderblock carbide drill bit to drill the two holes. The black base under the Lot-O is coated particle board and covered by a rubber welcome mat from Wall mart. The mat has tiny 1/16 diameter tips sticking up all over and acts as a cushion for the cinder block. The mat is glued on both sides of the particle board. The sound with this set-up is less than that with the big block. I do not know what the decibel rating is but certainly is less than before, considerably less. Also, and this is important, this configuration allows me to work at bench height, which is ergonomically recommended. Working with the old block assembly on the floor was a pain, literally, when bending to work on the machine. Bit much detail here, but hope it helps you find a solution. BTW, the Duke, was correct, in his post, (hats off to Duke) the dampening effect to reduce the noise does not affect the function of the machine. This assembly gets the same action as before when using the big block. Cheers, johnw

Duke, really a nice, well organized workshop. I like the idea of using a pan and the underbelly of the block having the rubber sheeting glued and then having the complete assembly framed in by wooden strips, "so it don't walk." I used a big block assembly on the bench and watched as my cup of coffee walked to the edge . So put the big block on the floor and after several months of stretching and bending a little voice said" hey stupid find a better way." So I did. This assembly has some vibration but nowhere near what it was and my coffee cup stays put......... I digress..... When I was building my humble work shop I used multiple two by heavies for the main frame of the bench and used four layers of plywood for the top. This did help in providing a solid "foundation." I like the idea of using blocks as a framework and then filling the top layer with sand, awesome concept. I guess the skills we learned being in the HVAC business have certainly helped us in our retirement. urahhhhh. lancemountain, sorry we high-jacked your thread, but we did provide some concepts you can chew on. Good luck in reducing your noise issues .Cheers, johnw See the image below. These plywood pieces don't warp. Each is glued to the other. Cheers, johnw

That's one hell of a workbench John.

wow Gents both set ups are quite nice!
I'm in a South Philly row home- very jealous of that space!
Those mats are a very good idea- I think I will add those to my Lot-O setup immediately,

I use these under my Air Compressor, Plan to order a set for my tumblers as well. Not sure if they'll help but it did make a difference with my compressor.

Here is my suggestion as follow up for reducing vibrations. The suggested application is for reducing the transmitted vibration to the work bench by a Covington Rotary. Following is a step by step visual application. Standard door mat from Home Depot, it has 1/16th inch projections. Add a regular ceramic tile with four felt pads. Position a second tile over the base tile to take the machine. Close up of the assembly. Rubber projections help absorb the vibration transmitted by the machine thru the ceramic tiles and felt pads. Final result is the machine vibration is greatly reduced. It works for me. JMTCW. Cheers, johnw

Mount the Vibe down with Vibration Isolators

Mount the Vibe down with Vibration Isolators
Wouldn't those defeat the purpose of a vibratory tumbler? I would think you want that thing to vibrate like crazy thus the reason to mount the tumbler on a heavy surface (I'm only familiar with the Lot-O). I'm new at this so just asking.

I would believe that the Vibe Tumbler needs to be bolted to a Mass (cement block) to have something to work against to push the rocks around. But these Isolators would be used between the Mass (cement block) and the table to help prevent the vibration from transfering and reduce the noise. Low frequency vibrations like these will transfer a long way if you don't try to control it. Plus a large flat surface like a countertop will amplify the vibration like a drum. Carpet Pad works well as a Vibration Isolator.
