Discussion in 'Vinyl Nutjob World: Turntable and Related Gear' started by Lou Casadonte, Apr 6, 2018.
I was thinking something simple for feet that are low to the ground and would create a glow underneath + acoustic properties: https://www.amazon.com/Inch-Solid-R...sr=8-1-fkmr1&keywords=pro-ject dampening feet . What do you think?
I use these - were considerably cheaper when I bought them many years ago:
Maybe these, or the sorbothane equivalents (scroll down)? Might dampen vibration better than the rubber ones.
I wouldn't worry too much as long as you've got it on stable platform that's separate to the speakers any bit of isolation will help and doubt you'll notice much different between different types. I would just go with whatever your cosematically happy with and use a spirit level to make sure it ain't wonky
Thanks, They were a little higher than i wanted but definitely in line with my original thinking. I decided to go simple. Appreciate the response.
I decided to keep it simple and went with Pro-ject Damper feet (http://www.audioadvisor.com/prodinfo.asp?number=PRDAMPIT&variation=4 ).
How thick is this base? Also, what kind of turntable will you be supporting?
The base is a minimum of 1.5in (it will be a little more with resin around the core). I have a Rega P3 but I wanted the base to come out strong enough for amps as well. The feet are supposed to do the obvious + 1 - isolate and absorb vibration while at the same time providing a cosmetic boost to the lighting which should create a blue glow under the platform. The feet I picked are only 1/2 in high hopefully satisfying the need. The feet aren't attached yet as we are putting a high gloss finish on the platform first. The process is evolving to support the unique needs of audio/cosmetics and once complete I had hoped to invite the fellow doing the work on here to describe the final process and create a discussion for those who may want to try the diy project or have similar interests. I'll post pics on this thread for the final product but we'll have to see about bringing someone else in here. If folks express interest specifically I'll reach out.
Some of the cosmetic stuff possible:
Is that epoxy and wood?
It is a resin that I believe is a higher quality than epoxy mixed with various things that create the colors and patterns. The resin melds with the wood and colors. Wood forms the core.
It's very pretty and all, but I'm scratching my head here, and wondering (but I must have missed something. I think there were other threads) --- what here does the isolating.
I think it is very reasonable, and may even be necessary (like you want to dance in the same room as the deck: yes, I was young back then!) to isolate a deck. The only real isolation table I have actually seen, though, was not very thick or very large, but nor was it very cheap and it employed some sort of floatation-type of technology. Now, that's isolation. The owner of that piece of kit was a serious 'phile, but he was no 'phool, and his isolation table served a real purpose.
Back in the day when we did leap up and down, on wooden floors, with those head movements you can only really do if you have a couple of feet of hair... the deck was usually on a shelf screwed to the wall. It was isolated enough to keep the needle in the groove.
That would be this:
and i basically went with the Pro-ject Damp It version of that. I did see those. The feet provide the isolation or at least damping factor. I liked the Isoacoustic GAIA http://www.isoacoustics.com/products/gaia-series/. but they were about 1.75in high and more $. I can easily add those or another pair of feet once i get it. @thad thats really where the isolation occurs and why i was mad about the feet. In the end I think it will about the damping/isolating factor and weight disbursement. I'm going to double check the strength of the resin itself but it should provide additional isolation.
I had a mad, crazy, suicidal washing machine once, that just refused to be balanced and behaved, One could measure easily 1/4-inch per side shake at the top when it started dancing. I never got it to behave, but I did succeed in stopping it demolishing itself and the house. I did so with some heavy-weight vibration-absorbing feet that also had that sorbothane stickiness that kept the thing in one place. Sorry, I can't quickly find a link, but they were were much more sophisticated, and moderately expensive. And they came from USA.
This is purely a mental exercise, and it might be quite wrong. In other words... guesswork! But let me have a go.
Imagining my old washing machine, on those feet, on its ceramic-tiled concrete floor. Imagine putting a turntable by it. I think the needle might be skipping. Imagine a wooden floor instead of concrete: the whole turntable would be leaping up in the air. Would those particular feet isolate a turntable? Well, obviously it depends where on the scale of protection, from humming electronics to a jack hammer, you are needing, but I'd say: no. And I'd say that the feet in the Amazon link would do far worse. Just guesswork.
There are all kinds of antivibration devices, and they are not all expensive. Sorbothane comes in all sorts of forms, and, if you want low cost, experiment with inflated bicycle-tyre tubes, and... stuff.
And, I suppose that meters to gauge the effect are easily come by, even for free --- as phone apps.
Make yourself a beautiful stand/rack/etc by all means. Not knocking that! Sure, that stuff looks good. But for vibration control, especially for a turntable, I think you have to look much further.
