Nice work on the speaks mang.

Thanks

Can I pick your physics knowledge about turntable stands?

With the damn springy floor that I've got in the apartment...going wall-mounted would be ideal if not for damaging the wall

Nice 'peekas

Of course you can.

Pretty much the only good thing about sleeping in Laguna beach is hearing the waves crash from your hotel bed.

Of course you can.

OK, given my really less-than-perfect environment (3rd floor, carpeted floors, no wall mounting available), how would you suggest building a stand to best prevent outside vibrations from affecting the 'table?

I've seen roughly two camps on this, one seems to be using a very light stand that's spiked to the floor, the other involves just getting as much mass as possible and putting the turntable on top of that.

johnecon1883: what

AcidBurn2053: you can take oyur dots and stick 'em up your pooper

AcidBurn2053: like that redhead wth her dhidlp

johnecon1883: drunk yeti.

johnecon1883: go to bed

AcidBurn2053: nevar

AcidBurn2053: got a chick's numerb

AcidBurn2053: fairly hot too

johnecon1883: no WAI

johnecon1883: dude

johnecon1883: this calls for celebration

johnecon1883: nice

[Acidburn 10]

but really, I want to touch her naughty bits

[Adrian_D 520]

3 hours to undo the last 4 bolts on the manifolds.

Time to grind a bit the turbo housing so I can unbolt it easier from the manifold.

Morning

Time to run downstairs and get some breakfast.

The second one looks almost DIY'able except the plexi cover.

That reminds me, I need to get out my heatstrip shortly and bend some plexi for some crossovers.

I've seen roughly two camps on this, one seems to be using a very light stand that's spiked to the floor, the other involves just getting as much mass as possible and putting the turntable on top of that.

I'm no expert in any way but it seems to me the approaches are saying:

1. Remove mass to push the frequencies at which the stand resonates into a higher passband, or

2. Add mass to push the frequencies at which the stand resonates into a lower passband.

I would guess that adding mass is a better approach. The amplitude of the resonant frequencies is decreased as mass is added and the passband is pushed down (much like adding mass to a door panel or layers to an enclosure). It seems to me that a large, heavy stand would be much more effective.

But Sean might have some different ideas.

Remind me never ever go to New Hampshire...

Hilary? Seriously?

[topgun 262]

What about using some sort of mechanism to dampen it?

wait, you have a method of forming plexi?

[topgun 262]

I don't see why you couldn't just heat it and bend it...

[Adrian_D 520]

I'm getting an 05 xxx 18

[Adrian_D 520]

I don't see why you couldn't just heat it and bend it...

Wouldn't it affect it's transparency ?

[JimJ 11]

I'm thinking more of something I can build out of the leftover ply, sand, lead shot, resin and other wood I have laying around here

The levitating stand will have to wait...

[JimJ 11]

Going with void-free ply would have been a lot less of a headache.

I've got a few spots where apparently there's a void right underneath the veneer layer, so there's a little "dent" in the surface...grr...

I dare you to wall mount it

That's just how I'm going to mount mine (well, as soon as I buy a TT )

[JimJ 11]

Yeah, but you don't have a landlord that'll get pissed with holes in the drywall

Once again, my folks' place would rock for this, I'd just bolt a shelf right to one of the big vertical beams and I'd never have to worry about vibrations

Came across this thread...http://www.homediscussion.com/showthread.php?t=94831 Seems to have the same issue I do, I like the hypodermic needle idea, makes sense to fill up the void.
