Suspension System for turntables

Hello everyone,

I've been watching some rave videos, gettin me all hyped up about mixing, like gets me in the mood, too bad i dont have a mixer to mix with! Anywho. I've been watching these vidoes, and noticed they got their decks mounted in some kind of suspension. What i want to know is how to make one of these amazing devices, as my 1200's pic up the slightest tap on my table, amazingly, cause the table is hardwood =S

I'll get a picture and show you what i mean, but does anyone know how to make one?! cause i want one. Found a sweet pic!

At work (organic chemist), my analytical balances have stabilizing slabs that they sit on. They look like this:

sample slab

They are pretty expensive, the one in the link is $300 and here is the describtion: For use on a benchtop. Use where space limitations prevent use of balance table. Just set slab on top of existing lab bench or desk. Substantially reduces vibrations which can affect performance of sensitive balances. Made of white epoxy resin. (Note: Other colors available on special request. Contact your Fisher Customer Service Representative for details.) Chemical resistant, easy to clean. Overall: 20L x 13W x 2 1/2 in.H (51 x 33 x 6.4cm). Net weight: 46 lb. (21kg).

Very heavy too!.

The only reason that they would have stabilizers like that is because they are a HUGE club and the vibrations caused by that many people dancing actually can vibrate the structure of the building! You know the myth that if all the people in the upper floor of a mall jump up and land down at the same time that it will collapse the mall? Well, you actually can because it in essence starts a small shock wave that travels down along in the floor. If they continue this then it will make a larger and larger shock wave until the floor will collapse under the buckling stress. This can happen because the wavelength of the wave that is created is very long and has a several second wavelength (from crest to crest).

Anyway, my whole point is that it is unessicary unless you own a huge club with a V. powerful sound system.

Some people put bricks under the feet of their turntables if your getting a lot of rumble from the table or room. You could try this out.

You can also make your own suspension with household items

Take 4 of the same can (ie fish can, tuna etc, but must be the same) and cut out the top with a can opener. Take 2 rubber bands for each can and but them lengthwise around the can so the two cross at the empty end of the can, place your turntable feet in this makeshift rubber band hammocks and you have uber suspension/anti skip. You have to make sure the can's diameter is bigger than that of your turntable feet beforehand tho.

LOL! Highly ingenious and resourceful Mike!

Hey good idea,
well like, would it be just the same if i bought a wooden base, with four poles stickin our, each corner, get another smaller base, attatch it to the corners with rope, or something similar, and then place the turntable on the floating piece of wood. would that do it?

I figured out something!!!!
My parents bought a huge painting. Came with heaps of bubble wrap. I decided to cut out a hexagon of bubble, wrap, fits perfect under the feet of the turntable. its floating on bubble wrap now! So yeah, anyone who has troubles, cut out 4 hexagons from bubble wrap sheet, stick one under each foot of the turntable, and you're set, if you still have problems stick more hexagons of bubble wrap under it!

I am not sure but wouldn't that without a "slate" quality table condition act as a trampoline???

No offense but I am sure technics designed there suspension and materials used better than the packaging delivered in

Nahh,
trampoline, pfft.
It works, so there is no debating! And it dont bounce either, the turntables are in complete harmony with my cabinet =)

Well again no offense but you might have failed to miss the point. Technics designed and tested the feet to sit in STABLE conditions. When I thought of shock prevetion, I think of isolating the turntables normal operating condition and not altering it

Meh,
Ohh well,
I think the bubbles have popped anyway

oakenfold demands a squas ball cut in half sitting underneath of every foot of each deck to ease vibrations and to make it easier to cue without skips due to the TT moving.

just thought i would bring that up lol

Posted by Haunted on Jan-20-2003 04:47:

whats a squas ball

Posted by VoiDeT on Jan-20-2003 06:50:

He means squash,
Its the little black rubber balls you use when you play squash, good idea =)

Posted by Acid John on Jan-20-2003 08:26:

ever thought that some of the ideas could be too bouncy?

cuz then everytime you touched the pitch adj., the whole turntable would shake, and probably cause more needle skips then it would prevent

so far, the best idea i've read would be the multiple cans and rubber bands idea. it wouldnt be too bouncy, but it would probably reduce lots of outside vibrations. but most of all, it'd be cheap!

most US clubs suspend the dj gear from the cieling (SP).....

Posted by Mpl4ever on Jan-20-2003 20:07:

The best solution......

They best solution is to buy Vestax PDX from the start!!!!
The base and the top part of the TT are made of 2 different polymer with 2 different rate of vibration absortion (I dont know the right term but I hope you guys understand). This considerably reduce the amount of vibration that get to you neddles!

I bought vestax and Im happy because I never have problem like that!

unless you play out i dont really see the point in a suspension system! well unless you weigh 30 stone and stand next to your TTs and jump up and down! but ive never had any trouble with vibrations/skipping

Posted by Rememberence_ on Jan-20-2003 20:57:

I've seen that "tin can & rubber band" idea a few times, except never with tin cans, but rather with rolls of packing tape. I think you'll find they are sterdier, works really well!

Posted by VoiDeT on Jan-20-2003 23:24:

But you'd think that method would make it even more likely to skip. Yeah sure it would reduce the amount of vibrations comming into the needle, alot. But think about it, it's just like having the damn thing on a trampolene. I have seen this guy on ta who spins on his bed! if you put those things under your turntables you'd be doin exactly the same!
