Help! New TT skipping badly....

Recently bought a used VPI Scout with JMW arm  9 in.  Set up on shelf om my SolidSteel rack where I have always had a TT. Could barely breathe without arm skipping. If I walk anywhere near rack, skips. Floor is carpeted over hardwood, quite solid, never had issue with Clear Audio or Rega table. Took to Audio Connection and had completely gone over and adjusted. Better but still bad. Put cork /sorbathane blocks on shelf and put 3 inch solid maple slab on top of that. No change. removed top shelf and put the cork/ sorb. blocks directly on frame, then maple slab. still skips. everything is dead nuts level, and as stated, floor is firm. Went in basement and put a brace between floor joists, nada. Tomorrow I was thinking of taking rack down and removing spiked feet. Odds this helps? I know some will suggest wall mount, but I don't want to spend anymore money if I can avoid it.As I said, Ive had other TTs in exact spot and you could dance with never a problem. Any input would be greatly appreciated.As I said TT was recently gone over and is set up correctly. Thanks

My wood floors are obviously springy, yours is solid, EXCEPT ...

Felt feet/rubber under each shelf, super solid JVC 7 layer Plinth.

The final solution: 2" square isoblocks under the 4 factory leveling feet.

prefer cork?

I start the stylus on the very outside edge and need to get 3 steps away before it hits the content. After that, never a problem, wait till end of side, or very cautious approach while playing.

I would try/return simple things before I spent any real money

Some TT designs are very susceptible to vertical movement, specific frequencies. I loved my Thorens TD124, but I could not stop vertical vibrations from getting to it’s bearing, even from far away, nothing worked.

You could say it was a fundamentalist: No Dancing Allowed.

My set-up is very similar to yours but without the issue. Maybe try using a different cartridge if you have one to rule that out? You didn’t mention what you use or it’s age.
Hoping for the best!

Thanks bslon for contact #. I have a set of Nobsound springs coming, hopefully they do the trick. Cartridge is a Soundsmith Zephyr lomi.
Again, thanks to all that offered help.

In case anyone is interested: I tried a set of Nobsound springs as advocated by Millercarbon. They did make a difference: I could now at least walk gently past rack without skipping, but its still too touchy for me to live with.    ?  would adding a few more help?. I know if I could put a steel lally column under floor it would probably do the trick, but my oil tanks and piping are right where it would need to be, so its not an option. Looking like I just might have to move on from this table.....
