Sturdy Turntable Stand

mijosyn,

"...put the edge of a stethoscope against the platform..."

Why edge? Why not membrane?

flupson, the membrane is very sensitive and will make a racket against any solid surface. It is extremely difficult to hold it absolutely still. The bell is usually covered in rubber and you want a solid connection to the turntable.  

mijostyn,

I misunderstood that you recommended the edge (of the stethoscope head) which would be, in some way, sideways. Bell is more logical. Thanks.

Did somebody just refer to my little buddy as flupson? Whoa! 🤡

I’m not referring to earthquakes, Mr. Smarty Pants. I’m referring to the everyday motion of the Earth’s crust. The specific term is microseism. See, you learn something everyday. Well, maybe you don’t, how the hell would I know? If Earthquakes was all they had to worry about LIGO wouldn’t have needed all the isolation stuff since their experiment was way out in the boonies. Besides Earthquakes and trains you can add high rise buildings, construction sites, beaches, roadways, bus lines, and areas like CA and NV with very high microseism activity.
