Of some peculiar reason haven't I noticed that you have a homepage nor your tone arm project. How far have you come?
Nice drawings, Illustrator?
leiade, do you mean that the dish shall float? If yes, not possible if the fluid is very heavy (mercury?) or the dish is light.
Also small O-rings as coupling between belt and dish, isn't this concept long gone? Too much wow?

Floating turntable
It depends, use archimedes formula and it will work,O-rings will not be the missing link it depends on the material used, O-rings with esoteric material can be find however very expensive.
Also small ring magnets of Neodymium will be used to lift the whole assy'.
The ring magnets can be mounted under the turntable and as this way be a type of decoupling.
Remember that many turntables used a perifier driving system some years ago, very often it was a kind of intermediate wheel with a sleeve bearing no damping liquid was found around it as it is in my "thinking".🙂
When the assy' is adjusted and started I can't see what kind of forces that can start wow in this design.😎

Hi,
One thing I forget do you see the adjustable passive drive to the right this is the fine tuning device.😎

The floating Turntable III
This is my last comment as I can't write Turntable 4 in the Roman way on my computer.
Of cource we must use four or more of the passive fine adjustment O-ring counter forces.

If you can make it totally floating, it's cool but a little bit messy...
Dissasters can arise:
My 3 year old daughter put pie paste (butter, sugar and flour) into my Martin Logan electrostatic speakers yesterday. How did I feel when I got the telephone call about this?

Call the insurance company
Ok!
This is the big problem for the most of us, how to get rid of human effect on our HiFi my ribbon tweeters is gone and I have to make two new 2 meter ribbons wich consists of esoteric plastic film and special Skultuna aluminium foil made for ABB laminated in a special assy' for SOTA lamination of extraordinaringly light Al/polyimide wafers.😉

Peranders,
it is still in the design stage, about 97% completed. But in the meantime i closed my jaws around designing a mechanical version of it, LT-2, no air bearing, completely different look but 100% same geometry and parameters collected with the LT-1 can be used for LT-2 and inverse. LT-2 design is 100% completed.
As i have very limited funds at the moment, LT-2 will be 1st. But i intend to make both a product. You may understand, i am not particularly eager to discuss possible products in public. Once they are placed on the market, this may become another matter.
Drawings are plain AutoCAD. Construction drawings, i work from those, i draft everthing in 3D. What you see are screenshots.
leiade,
nice idea! no, i don't tink this TT will have too much rumble.
Your friend added a magnetic bearing. Maybe you consider to add a Teflon/ruby ball axial bearing, couls ake your life easier.

guys!
you are really takin' off with this!😀
Some day a guy will propose a anti gravitational device to hold the platter up and strong rotaing magnetic fields ( like MRI) ) to spin it up
Houston this is eagle one. we are ready to land now.

Levitation
Yes I have an idea about levitation if we can consentrate a high tension dc voltage 500kV or more to a needle maybe we can levitate the platter.
Another way to make it is to use electromagnets same type as they use in junkyards but of course not such as big maybe... but no I stick to my ordinary vinyl flywheel a picture will come, hold on I comin'.

Yes the name is Eagle a cosmic sensation the spinning flywheel from outer space laying in melting led and is powered by background radiation.

That can be wise because the result is uncertain I suppose and announce "vapour products" isn't very good (compare with "vapour ware").
I wish you very good luck. It looks very nice and professional.
Hello, my name is Bart. It is a great pleasure to meet you all.
I am in the middle of building my DIY TT. When I was searching the web for Ideas I came upon this thread,
read it, and was very impressed with the amount of knowledge and wisdom in this think tank. I think I can
contribute. In a local surplus store I found a box of ultra smooth glass disks in thre sizes. They are approx.
50cm, 35cm, and 20cm in diameter at 3mm thick. They all have holes in the centres of about 10cm eccept the
smallest disk whih looks almost exactly like a compact disk.They seem to have a layer of gold sandwiched in the middle.
these disks are so smooth that when stacked together they cannot be pried apart, you have to slide them apart.
I believe all these are from hard disks. They can be implemented in the unipivot ball air bearing. A disk could be
in the bottom of a teflon coated cooking pot, the molded epoxy for the ball then also placed in the center , cup side down,
then molten vinyl poured in to the appropriate depth. The teflon would act as a release agent. That's the platter. The plinth
could have a recess for it's disk which would have holes drilled in it for the air nozzles. All kitchen table DIY, no machining,
one very angry wife.

Bart.

I apologize for my first post I copy/pasted it from notepad and didn't preview 
. I hope you can make sense of it all.

Angry Wifes
No big problem all girls grow up to women and when they caught a man they are begining to transform to... exactly angry wifes.
It is an ordinary evolution process, don't be scared boys I have lived with a angry wife for 25 years now and I haven't suffered from any big injures.😀

,3min? I thought it said 3 months! 😉
Wow, the creative juice is flowing again on this site!
Ilusus:
You got me going again, I like those ideas,
I'm not sure if they all will work but it pushes my buttons:"
Ball air bearing and super flat radial,
make it in your kitchen,
angry wife.
peerfect.
Mabe you will end up sending your disks around the world so we all can make platters. I suspect you are right, that they are old hard disks. Those suckas must be REALLY flat!
It looks like I'm going for it. Because of my work schedual I cannot start untill Saturday, it's a start nontheless. I'll keep you posted on the results.
Does anyone know of an efficient way to melt vinyl? I would like to keep the mess to a minimmum. Any suggestions?
I also found a great source of DIY tonearm tubes. Archery stores carry various diameter arrows made of carbon graphite or aluminium or combinations of both. Most bow hunters use custom arrow lengths, so the shops usually cut the arrows down for the customers from a standard lenght. The leftovers are usually long enough for a tonearm or two, and the shopkeep will most likely give them to you for free. Lucky for me my father in law owns a hunting supply shop. I know that not all of you may have access to archery supplies, sooo, if anyone is interested I can send some out.
