Sorry if this is in the wrong area, I know this is not very technical. [:$]
I was tired of not being able to listen to my vinyl properly, due to vibration resonaces being transmitted to the turntable. I decided to build a stand that would hopefully eliminate any resosnaces from getting to the turntable. I read somewhere that people were attaching foam rubber to the underside of concrete paving blocks, and that effectivly qwelled the vibrations. I decided I wanted to do that, but with a slightly more asthetic outcome. After looking at my local Home Depot, I selected two 20"x20" ceramic floor tiles. Then I found a 17"x15"x1" section of high density polyeurathane foam at the local Joann Fabrics craft store. A little adhesive and black paint later, I have a solid turntable stand. This thing is heavy, right at 17.5 lbs.
Materials and tools: (rounded to nearest $1)
(2) 20x20 tile- $3 ea
17x15x1 foam- $5
marble adhesive- $5
caulking gun- $2
throwaway brush- $1
flat black paint can- $1
Total- $20!!
Note that I got a building permit from the SWMBO before proceding [], and used the dog's blanket to keep the kitchen table clean.
Painting the foam is unlike any other painting I've ever done. Normally you would start with a few light coats prior to the heavier coverage coats. Not with foam. Bascially I threw as much paint at it as I could, emptied the can, and I still don't have 100% coverage. But oh well, it will be basically hidden.
The entire process only took 30-40 minutes, and that's with me being all OCD. [] I'm not good with building things at all, so the fact that I could complete this says volumes about the simplicity of this project. Hopefully this is something you could build and use (if needed obviously).
I'll post up vibration dampening results results here shortly, when I'm confident everything is dry.
