Turntable wall mount DIY

I recall a friend mounting his shelf from the ceiling using heavy duty fishing line and four adjustable turn buckles. I must admit it looked seriously cool just hanging in mid air . You could hardly see the line and the turnbuckles allowed for leveling as well as adjustment for initial stretching. He used a one inch piece of acrylic for the platform.

Chris -- how did he keep it from swaying?

Thank you for your replys.
I have built a shelf for about $20 using L brackets found at the local hardware store, a salamandar designs shelf found at a salamandar dealer. Must say that this is the best tweek I have ever done. It mad a huge improvement, I suggest this to anyone who has a turntable. It takes two people & around $20.
I have changed amps & heard less, much less. I now must listen to all my records again, it's like I got a whole new record collection.
I will have photos on my web site soon.

FWIW if you mix the materials for the shelf you can get better sound out of it. Layers of dissimilar materials with varying resonant frequencies will help to reduce or eliminate the effect of vibrations.

I did use some audioquest sorbathane between the wall and L brackets & the shelf & the L brackets.
