A Turnbuckle In Time Saves Your Stylus

I once lived on the second floor of an old farmhouse with a springy floor. How it got in my pants, I'll never know! I had a VPI TNT turntable at the time, on a VPI stand that had been filled with leadshot and sand. It was heavy! But the stand still shook and the 'table's suspension couldn't deal with it so the stylus jumped around in the groove, which was not good for it or for the speakers that had to endure intense "pops."

The large horizontal mass of the Eminent Technology II air bearing tonearm only intensified the problem. It was not a good playback environment for any stylus. Nothing I tried worked to limit the floor shaking, particularly at one location between the couch and turntable stand.

Then someone told me to try a turnbuckle or two and that solved the problem—as long as your stand is within a turnbuckle's distance from the wall behind it. Just wedge one turnbuckle between your stand's top shelf and the wall behind it, by turning the screws outward until you achieve a tight fit. Try a second on the other side of the stand but be careful not to wedge the second one in too tightly or the first one will fall down.

Getting both turnbuckles equally tensioned may take a few tries but it will be worth the effort because then you'll find the turnbuckles have mechanically grounded the stand to the wall behind it and the shaking and groove skipping will stop—at least until eventually the micro shaking will cause the turnbuckles to both slip and fall.

cool tip

Ha,

That's an interesting way to transfer the vibration...anyone living upstairs with other home remedies for solid hifi stylus tracking?

Cheers,

That's a great piece of advice and just might solve the problem.

Once again, makes it worth looking by analogplanet while procrastinating before starting to practice a presentation for this week....

I have exactly this problem, I live on the third floor of an old building, constructed around 1900 - 1905. The floors are actually suspended. In my living room where my system is set up, just walking around can get the stylus jumping (and the woofer baffles pumping in and out). Not good for expensive stylus, so I try to limit the amount of dancing about in the room... 

I've tried all sorts of things to try and weight the floor down to stop the bouncing around, but nothing has really worked.

Will be interesting to see how well this solution works.

Turnbuckle solutions

frown Wouldn't this now transmit vibration to the TT, which was previously supposed to be so isolated and perfect?  Why would such a pricey TT, have these defects?  Looks like over priced, over priced, under performing  bases, so pushed by audiophiles, is meaningless.  Mounted to wall eliminates problems.   TT's are still as obsolete as ever, even at $150,000!  $30 CD players don't have these problems!  Makes ya wonder, why play TT's in the 21st century? And DSD/SACD has no noise.  Vinyl, is truly obsolete.  My old AR XB TT in the 70s.  was $67.  Didn't have any issues like this  Only side to side knocks would be trouble, up down, isolated, $67 !!!

It's amazing that such underdeveloped brains can survive long enough to almost learn half a language with enough werewithal to spew such mindless nonsense. Please, CEDUP, by all means, go enjoy listening to your $30 CD player and leave those of us who can tell the difference alone, you vapid troll.

You have perfectly captured the essence of this guy. I know who he is and he's a sad, pathetic individual..but he is worth a laugh...

Whoa!

No it would not. It stops the shaking floor from bouncing the stand by "grounding" the stand to the adjacent wall. It is not a turntable problem, it is not a stand problem, it is a floor problem!

No, good stands are not meaningless...anymore than a boat is worthless because it won't fly. 

Yes, wall-mounting can solve the problem if you can mount the wall stand to studs, if the turntable isn't too large and/or heavy and if you own the home. Many landlords don't allow attaching such devices to their walls.

As for your suggestion that vinyl is "obsolete"--ha ha. That's funny. I'd say your opinion is what's obsolete!

Audio grade turnbuckles?

smiley Certainly not just any turnbuckle.  One plated in gold, and special circular ends that meet audiophile standards.  I bet the $150,000 TT that shakes on springy floors sounds great don't it?  When it can play a record!  Don't the threads of teh turnbuckle have to be a special pitch, so as not to change the sound?  I can see Fleece Tech coming out with audio grade turnbuckles.

A jealous moron "speaks"

Listen Carl, you can change your name but I know it's you by the lame comment and because you still can't spell "the."

In fact the $150,000 turntable does not shake on springy floors. Sorry to spoil it for you.

Any turnbuckle will do, thank you, just like any douche bag perfectly describes you.

For those of you who don't know who this douche bag is, he's a guy who is intensely jealous of me and follows me around on the net writing negative and sometimes defamatory things about me and my work. 

He once posted on Amazon.com that my turntable set-up DVD consists of nothing more than me reading the instruction manuals to turntables while looking into the camera.

He's a very sad, sad person who should look in the mirror and ask himself what kind of a douche bag he is.

No doubt this new website positively drives him crazy.

Springy Floors

Back in college we suspended our TT from the ceiling.  2 or 4 eye bolts, a wooden shelf and fishing line were all that was needed.  Worked like a charm.

Mikey's solution is a good one, and I have often done something similar by wedging a wood block between the back of the stand and the wall to short circuit the lateral motion at the top of the stand. I usually position the stand so that I get a good tight fit with whatever block I'm using, but the adjustable turnbuckles Mikey suggests make that unnecessary. One advantage of a wood block is that you can usually add some duct tape to hold the block in place against the stand, eliminating the slip out problem.

Wall-Hung Platform

If you floors are too springy, remove any contact with the floor.  Several makers produce a sturdy wall bracket for turntables.  I made my own with double-layer MDF shelf about 2' x 2' with 18" MDF brackets below (right triangles -- mine had circles cut out to give it a Buck Rogers spaceship look).  Make sure to mount it securely to either studs (via lag bolts) or masonry (via heavy-duty molly bolts or lag anchors).  I thought I was still getting some subtle LF rumble so I added a second 1.5" platform and put a 20" bike innertube between the two thick MDF slabs...I put nice roundovers on the MDF slabs and gave them a faux-granite finish....best TT arrangement I ever had...

Bouncing stylus problem fixed

I just put two turnbuckles between the rack and the wall.

Hey, problem of my bouncing stylus seems to be mostly solved. I can walk around now pretty much normally. Great tip. Works well.

Wall mounting for me is not an option, it's an old house and there is a door, locked, but a door right behind the rack. Door mounting the turntable is just not an option.

Why this happens

This is a problem I have encountered frequently, and I think it's useful to understand what's happening.

A suspended floor does not move up and down vertically like a piston when you walk around, it tends to move more vertically towards the middle of the room, with far less movement where it meets the wall and the floor joists are attached to the supporting wall studs. Most people position a turntable stand near the wall, and the result is that the rear legs move very little, while the front legs which are perhaps two feet away from the support of the wall connection move vertically more.

If you imagine a stand where the rear feet remain still, but the front feet are moving up and down vertically, the result up at the top of the stand is lateral movement towards and away from the wall. The rear legs act as a fulcrum, with the front legs rotating about that point. The taller the stand, the more pronounced the effect, because the amount of movement at the top is based on the ratio between the distance from the rear feet to the front feet, and distance from the bottom of the stand to the turntable mounting surface. The taller the stand, the more small amounts of vertical movement at the front feet gets translated into larger front to back motions up at the top of the stand where the turntable sits.

Lateral motion is a real problem for most turntables. A suspended turntable can usually handle pistonic vertical movement pretty well, but lateral movement will provoke the suspension in unpredictable ways, and can shake the stylus right out of the groove.

A really simple solution is to use a lower stand. Try putting the turntable directly on the floor if you don't believe me, I promise the problem will be reduced.

Mikey's solution is a good one, and I have often done something similar by wedging a wood block between the back of the stand and the wall to short circuit the lateral motion at the top of the stand. I usually position the stand so that I get a good tight fit with whatever block I'm using, but the adjustable turnbuckles Mikey suggests make that unnecessary. One advantage of a wood block is that you can usually add some duct tape to hold the block in place against the stand, eliminating the slip out problem.

A more elegant solution can be used if the room under the listening room is an unfinished basement. Install a builder's adjustable prop jack in the basement, so that the top of the jack supports the ceiling/floor above at a point directly under the front legs of the turntable stand. It helps to use a length of 2x4 between the jack and the ceiling/floor, to spread the support across both legs of the stand.

The widely suggested wall shelf works well too, although I take issue with the way many wall shelves are designed.

In my experience, adding lots of mass only makes the problem worse. A really heavy stand seems to pre-load the floor in a way that gets it moving more easily.
