How to isolate turntable from footstep shake or vibration

@millercarbon .

First thing I learned out of college. Got a job as electro mechanical engineer. I needed to have a perfect gripping material to coat a rotating drum that was to pull fiberglass. I got out my calculator and tables of coefficients of friction. After a couple hours in the books, I realized I was getting no where. I quickly fabricated a little drum with motor, and went out and bought every brand of PVC tape, adhesive, and Saran Wrap I could find. Then just wrapped the drum and tried it until I found one that worked perfectly. Then I built a 10’ high drum and used the material I found by quick trial and error. A couple years later got into audiophilia… where I quickly learned peak wattage was meaningless… and the watts RMS was nearly so… and that I must try interconnects and power cords in my system. It’s a good lesson to learn. 

Engineer, you say. Did they drive you out of the profession? Because all the engineers around here are the worst most tone deaf pontificators of that which does not in reality work I have ever seen. You must be a pariah or something. Welcome! Welcome to the club! The club of real world practical thinkers! Our motto: We get results! 🤣😂😁

Darn millercarbon, I am stuck agreeing. In medical school we learn to do things perfectly according to the state of the art at the time by learning from people who already do it perfectly. But, looking back at history it took a lot of baby steps to get there. Perfect is only a perspective in time. As time changes so does perfection. I am sure if da Vinci were alive today he would show you are all the places he made mistakes on the Mona Lisa. 
Being a perfectionist does not mean you are paralyzed. It certainly means you are never happy with what you do, or what anybody does for that matter. It is not a very happy place to be.

Try this.....nearly cost free.   Put a piece of wood between the wall and your turntable table....Wedge it tightly and it will work.

I used springs under my tt legs took some of the bounce out but have also wedged a board between the equipment rack and wall the bounce is gone unless someone jumps rope in the room. I think Fremer offered this as a cheap solution instead of wall mounting.
