DIY Isolation Platform

That should work really good w/ big isolation transformers (plus some hardwood boards & cones). I've used foam/bubble wrap with my power delivery/noise control gear successfully.

This is what I just did.Made a furniture grade box out of oak veneered 3/4" plywood.Mitre joints .Stained and laquered it by hand.Also made a cover(lid) out of same material and glued oak trims(mitred again) on the edge of all four sides.The cover is bigger than the box by 3/4" of an inch all around.On the underside of the cover piece I glued a second 3/4" plywood that is a little smaller than the inside dimensions of the box.Inside the box I laid a 14" bicycle inner tube and then placed the cover on top.So the cover is now resting on the 14'bicycle tube and my CD transport is placed on top.It's a homemade isolation platform.My box is deep so I might add a second horizontal chamber filled with about 1" of lead shot or fine sand ,plywood on top ,then 14"bicycle tube and cd transport
on top.It was a fun project with very good results.
Hope this helps and inspires you to put your tool belt on,this weekend.

I use a Rubber/Cork/Rubber pad under my TT. This one is a 18" x 18" x 7/8" pad ( like the Isopads) and weights about 7 lbs. The Psychic knows the product because he got a pair the last time he visited our island. This pad is used under power transformers, heavy motors and other industrial equipment to isolate and/or reduce vibrations.

Hi Jahaira and Psychicanimal,

Whenever a compliant mount is used under a component, the amount of compliance (how springy the mount is) must be optimized for load weight. A mount designed for a very heavy device like a large transformer or motor will be significantly less effective for a much lighter load weight such as a turntable or other audio component.

In physics it is called Mass Over Spring where the compliance of the spring must be optimized for the mass and weight placed on top of it. If the mass and weight of the load is significantly under or over the optimum range for the particular spring employed the ability to reject displacement (vibration) will be significantly reduced. The term Spring as it is used here does not mean just a coil of metal but refers to any compliant material that is placed under the mass.
