Turntable Foundation

[GeraldB]

I remember in the late 70's working part time at a local Radio Station tech dept. The turntable pedestals were filled with sand to add stability eliminating vibration,skipping,etc from all the busy activity in the studio while spinning vinyl. Anybody got any thoughts,pictures,ideas for a home brew pedestal for the TT?

First of all you need a turntable which can be mounted in it's own plinth. And can have it's own tonearm. We use large pedestals which have 600 pounds of sandbags inside. We like overbuilt in radio.

How about a wall mount stand with a sand filled base under an air bladder base (I use two Bright Star bases under my turntable). It isolates quite well for me.

As Dukiedook suggested a wall mount stand, Target or DIY, will go along way to isolating your turntable. Also as he suggested a Bright Star Audio sand box and air bladder will go a ways in duplicating what the radio stations did to avoid vibration. Again you coud DIY the sand box. I plan on adding a Bright Star Big Rock 1 I already have to my Target wall shelf when I reconfigure my turntable setup. As Kent said overbuilt but vibration free. Probably cheaper in the long run then trying to control vibration with feet and other accessories.

Since I can't do a wall shelf, I will soon be getting a pedestal built as I described at home.

Kent post some photos of the pedestal when you get it finished and installed, my guess is not many AK members have seen one.

Another solution is a surplus optical instrument isolation platform or an electron microscope isolation table. They weigh a tonne, so buy local. They cost a fortune new, but can sometimes be had for chump change, especially at government auctions.
