My VPI MK3 skips if I walk near it.Should this be?

I'm getting back into analog after a 20 year leave and
was wondering if maybe my Grado cartridge a Silver Prestidge
has the bouncies on my Morch UP-4 Arm with red dot,or is it the table itself.I haven't called VPI yet.I thought I would ask u guys first.Are the springs adjustable on the VPI,if so how? The info supplied with the table doesn't say anything about this.I use to have an AR along time ago and you could adjust the tension of the springs from tight to loose to balance out table.Is this the same principal with this table?

My HW19 III used to do this, too. I am not aware of any spring adjustment. To stop it, I braced the support shelf against the walls behind and beside it. (It was in a corner.) I also inserted folded paper shims between the plinth and the wooden base, to change the resonance of the whole system. Good luck.
Assuming this is a new location for your turntable, the problem is most likely a "bouncy" floor, not an issue with the turntable or arm. As suggested by Jameswei, you might want to look at ways to make the support platform (rack, shelf, whatever) more stable and isolated from footfalls.
VPI has reversed course on the springs and before dicontinuing the series they went back to sorbathane pucks on the MK III and IV.

They actually sell the older design pucks to retrofit the tables that were sold with springs. Who knows they may give 'em to you. (I doubt it)

I have a MK III that has the pucks and there is no bounce when used upstairs on a pretty springy floor. My previous suspended Thorens bounced if I even thought of walking anywhere near the TT and the VPI resides in the same exact location.

So just change out those springs for the sorbathane pucks.

Good Luck

Paul's comment is on the money. I have had a VPI HW-19 Mk4 for many years, and my older home has rather "flexible" wooden floors. Like you, the tonearm on my VPI TT bounced whenever there were footfalls near its' location (it even bounced if our overweight cat jumped down from the couch to the floor). I tried a lot of different approaches to solving the problem, and none were totally effective.Then, about 2 months ago, I replaced the TT's spring suspension with the Sorbothane pucks from VPI, and I no longer have a problem with tonearm "bounce". (An added, unexpected "plus" is that bass frequencies seem tighter.)

The pucks (and the Scout / Scoutmaster cone feet) can be purchased from Elusive Disk. Here's the link:

Installation of the pucks requires some minor changes to the turntable. Rather than go into all the details here, please drop me a personal E-mail and I'll tell you what to do.

One other comment: if you decide to buy the Scout-type cone feet, note that it is less expensive to buy them separately from the pucks, rather than buying the upgrade package which includes both items.
Thanks for the advice I might give the sorbothane pucks a try.The table came with brass tiptoes that sit on top of flat brass inserts.Come to think about it tiptoes tend to
not absorb energy very well,but transmit it very effeciently.Sorbothane would probably work very well.
If you have a basement or crawlspace you can put floor jacks under your rack. Also you could try a Air Mass 19 from Bright Star Audio. I'm surprised to hear the pucks work better than the springs. I may have to give this a try...
I've heard VPI is going from springs back to pucks. I have a Mk 4. I removed the sorbathane feet and istalled brass spikes that threaded fine and were the same height as the SAMA. Much less motor vibration. Then I saw that Black Diamond Racing is making vibration kits for the Scout and Aries. The kits are 4 carbon fiber pucks and a 5" round platform for the Aries. So I bought the Aries set and it was like magic. I have one of the new SAMA's so it was a bit of a trick to get the motor on the platform. But the spikes go into indentations in the pucks and the motor on the platform. I can't recommend this enough. Music Direct sells it. They also sell a BDR record clamp that is out of this world. $300 though. Nice thing is you get a 30 day money back...
