VPI HW 19 - replacing springs with pucks or cones

Mred,
I have'nt tried the NAVCOM [rifle dampeners, limb savers] material yet. Just threw that out there as a suggestion hoping someone had and would comment on it. My guess is that you would have to cut them down too, but give the vendor a call. Maybe they can give you the dimensions. You also may want to try those scientific supply places.
I'm quite happy with the noodle material right now, nice improvement over the sorbothane, so I did'nt pursue it [Navcom] any further.
The nice thing about the noodle material besides the sonic improvement is it's very cheap and can be cut to any height and width. So just cut it down and trim it till it fits . You can use your springs as a guide for the width. You may want to glue some thin wood strips to cover the holes where the springs went.
I suggest cutting out the middle man so-to-speak and just put them between the plinth and whatever you're resting the table on, not between the plinth and base as is done with the springs or sorbothane. This is also Mike @ VPI's suggestion. If you have a SAMA they should be cut around 3.5 inches high. You can use
some rubber washers if needed to help level things out.
Hope this helps -Frank

I would think that the noodles between the base and plinth(where the pucks and springs are) gives you more isolation, as it is another layer of isolation. I would think then the base has some isolation from what it is sitting on via cones or the like ?

Wayne,
I agree the base can be another layer of isolation providing you can properly isolate it. My reasoning was why bother going though the trouble and expense of isolating it when you can just take it out of the equation. Aside from adding their own sonic signature, those pucks, cones etc... can get pretty pricey.
Personally, I wish I could remove it all together, but then
where will I rest the dust cover?
Like I said the beauty of this stuff aside from the fact that it really works is that it's dirt cheap so you can try it every which way.
Take care - Frank

Frank, if you take away the base, you would have a Basis 1400 !!! Which is just a plinth sitting an 3 posts !! That would be a Basis HW-19.

Where did you finally get the noodles, and how big around were they ? Mike at VPI told me about them a year or so ago.

Wayne,
Then the Basis 1400 must be a damn good sounding table!
But kidding aside, IMO the TNT platter and the VPI HW plinth are superior to the Basis two slabs of acrylic.
You can get the noodles at, get ready for this

Toy's R- Us

or any swimming pool supply outlet. But it's a seasonal thing,
so if they don't stock them just Google pool noodles. They usually come 2 - 3 inches in diameter.
There is also rectangular shaped packing stuff made of the same material [polylam]. This is what I wound up using as the noodles were not yet available.
