Anyone here remember Townshend's air bladder platform from the 1980s?
This was and still is a very effective method of isolating vibrations, a idea simply taken from the scientific and medical communities.
Want the very best available today , look no further to what is available to the scientific and medical communities....$$$$....
There are limit's with with this table and only so much can be done.
Returning to Townshend's method,.... Find a used Townshend OR try a slate platform sitting on a mountain bike inner tube.
Fold and tie off to fit under the platform and adjust air pressure. Yes low air pressure.
Tables experimented with this method, Raven One, re-furbished Micro Seiki 5000, re-furbished Technics SP 10 MKII.
Definitely works very well with belt drives except the Technics and is "thousands of dollars" less then Minis K, Vibraplane ect. from the science community.
However if you must have the very best look no further.
