VPI HW 19 - replacing springs with pucks or cones


I have a VPI HW 19 turntable and have read in several places about a modification whereby the suspension springs are removed and replaced with sorbothane pucks or cones. Does anyone have experience with this modification? Opinions as to benefits vs. detriments? Most importantly, what size/brand/type of puck or cone works best? Thanks.

Wntrmute,
What were you using before the limbsavers, and aside from helping to isolate your table from the closing door was there a sonic improvement?
I gather you placed them between the plinth and base. If you did, was any modificaton of the base or the limbsavers necessary?
I've heard alot of HW-19 users replace the springs with the sorbothane to help eliminate footfalls. I've never had that problem as my TT is wall mounted. I just wanted to experiment with different materials to improve the sound.
Thanks - Frank
The noodle material is called 'polylam'. I used springs, sorbothane and just recently changed over to the polylam. So far I prefer it to the springs and
sorbothane. Give Mike at VPI a call as he was quite helpful regarding this.
I wound up using packing material made up of the same stuff as the noodles.
I cut it up very carefully with a large, sharp kitchen knife and had to cut quite a lot of pieces before I got enough of them to be exactly the same height. Getting things level was the most tedious part. I placed them on my wall mounted shelf and rested the plynth on them , not between the plynth and base so they wound being 3.5" high. If you don't have the SAMA this is also good way to isolate the plynth from the motor. If you want them between the plynth and base, I think around 1.25 inch tall should be high enough. Give it a try. It's cheap, and only takes a few hours.

Another thing you may want to try instead of the sorbothane is Navcom.
I beleive this was VPI's original replacement for the springs, and when this was no longer available they touted the sorbo. Hunters use it to dampen vibrations on their riffles and arrows, They're sold as Sims Limbsavers and are available at:

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
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
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.
Piedpiper,
I understand that and I was'nt trying to compare the 2 tables. What I was trying to say was, just because it now might resemble another table, it does'nt necessarily make them the same or even a hybrid of the two.
Wayne,
Actually I have 4 pieces of the noodle stuff under my table.
If you ever get around to this mod, send me an eMail and let me know what you think of it.

Piedpiper,
Apology accepted, even us innocents can get touchy sometimes when it comes to our gear.
