Home made turntable isolation

After researching many different issolation platforms I have decided to make my own to hold my TNT JR, based soly on price. I am going to have two peices of 10ga stainless lazor cut to my spec. (I call on a couple of accounts w/ lazors. The problem is the core, I have researched and found fiberglass suppliers carry many different materials high and low dencity foam. The one I would use is a 1 1/2 inch honeycomb but the honeycomb stands on end and I dont think this would be the best option to dampen vibration. If it ran the other way it would be my choice hands down. Also balsa wood is availible. I will have about $125 into something that would be $900 (I checked)What do you guys think on the core. David

Cylinderking_1,

Another suggestion would be to use cork between the sheets of steel. It's much better than foam. Has good isolation properties but not the mushiness of foam. Also, cork doesn't collapse like foam might under continuous weight.

This might be 2X the price you quoted of $125 in your post -how about a Neuance shelf from Ken Lyon? I have 2 friends who are using it & swear by it. One has it under his Spacedeck & the other under his VPI Aries. The Aries perf. went up a few notches w/ the Neuance shelf under it. Maybe you've already checked into this & decided it's too expensive?

I went to a NY Audiophile meeting where the guy poured a cubic meter of concrete on a steel dolly that had threaded cannisters for leveling. Seemed to work with foot falls and high sound pressure levels.

for the isolation of the tt, try this: you could call it 'hifitommy's toysRus isolation trick'. go to tRu and buy two paks of children's water toys that have the rings and arm floaties. use the four arm floaties from the two packages of toys. inflate and place a mdf board the size of your tt on them, and adjust air for levelness. this gives a stable and DEAD isolation for your tt. and its SOOOOO pretty. an enterprising chap could make an inverted box that doesn't touch the cabinet and put veneer on it for looks i suppose.
you can now hammer on the cabinet with VERRRRRY little or no sound thru the spks while the cart is on the disc. its so cheeeeeeep that its embarrassing.
