Tripods as turntable or component base?

Perhaps one of you who is into photography or owns a camera store can try this experiment. Since the tripod is the most stable base (ask any photographer or physicist), has anyone experimented with using them as component bases? All the best turntables and many other components now have 3 legs instead of 4 for that reason. One school of thought says heavy tables for turntables are better (less amplitude of motion for given energy input); others say not (energy storage, pickup of airborne sound energy). The people who used to market Linn specifically recommend flimsy tables (!) but they were fruitcakes. How about taking three tripods, setting up one under each foot? A cheap experiment if you have the tripods... Your colleague in science, hifigeezer

The reason manufacturers use three legs instead of four on a photographic tripod has nothing to do with the superior stability of three vs. four legs. Rather, three legs satisfy the minimum requirements for stability and this balances out the costs of engineering complexity, manufacturing cost, and weight penalties if you use more legs.

Reason for a tripod or 3 feet under a piece of gear: (1) Easiest to level; (2) The weight of the supported object will be evenly distributed among the 3 pods, once the object is level and if the tripod is properly implemented, (3) Fewest paths for vibrational energy to travel from the shelf or stand into the component. These are not trivial advantages, but extreme stability is not among them, as others have noted.

what do you expect?
something serious?

If you use a photo tripod as a component base you have effectively changed it to a monopod base resting on a tripod base. Seems to defeat the idea of a tri-point component base and replaces it with an inherently less stable monopod platform.

Hi, Hi,

Seems that some of the posters missed your idea about using a tripod for each of the turntable base feet/points for a total of nine legs. I think it may have merit - "worth a try" - if you could find very solid and stable tripods with easily adjustable height. A surveying tripod with spiked feet might work well. They're used to support equipment that costs thousands of dollars and take very fine measurements. And you could probably find attachment adapters that would screw right into the turntable base. It might look rather goofy but on the other hand it could be an unusual conversation "piece".
