Walker Vortex Vacuum Wand for VPI


Hello all,
From a thread over on the Asylum, I noted Walker has introduced an Arm Wand for VPI RCMs.
After reading it's description at Elusive Disc, I can't help but think that this Delrin Wand, with no protective strips, coming in contact with the vinyl, no matter how one adjusts the Wand Tower, will be "kind" to the vinyl?

The other item included with the Wand, is two little O-rings, placed on Spindle, said to keep the record from touching the Mat. Wouldn't a rubber washer serve the same purpose?

Perhaps too new to hear other's opinions? I like the idea of never needing to worry about velvet strips going bad, less chance of cross-contamination, etc, but just cannot seem to get past the idea of the Delrin contacting Vinyl? Mark

My experience this morning has been dismal.

First of all, the slit in the Walker tube is thicker than my VPI tube. I was expecting the opposite (to increase suction).

I cannot get a record to vacuum dry. It still looks visibly wet and feels damp. I suspect some of that is because the felt on the VPI tube worked in tandem with suction to dry the LP.

I have spent an hour playing with height adjustments and while I've seen improvement, I don't feel it is right. I'm using a thin throw away record, but if the setup is this sensitive to height, using LPs of different thickness is going to be problematic.

Also, because of the rings, the tube makes more solid contact near the spindle than it does the edge.

At this point I'm at a loss of what to try next.
Update: I did notice that the slit in the tube wasn't oriented perfectly downwards so I adjusted it. Here's what I now experience:

I have the height so that I can see the record lift up slightly to meet the tube (which I assume is correct), but I get a screeching sound, sort of like a cross between a children's party horn and an elephant. It's quite, um, alarming, but the record does get vacuumed apart from the outer edge and close to the spindle which remains moistened.

Has anyone else experienced this sound? I'm afraid to try anything but a junk LP, but of course with junk LPs I can't tell if I'm adding snap, crackles and pops (no visible scarring).
Madfloyd, try moving the stop ring higher up on the tower to allow the tube to pull all the way down onto the record.
Another new user I've been emailing with was having a similar problem to your first post (not the screeching, which I don't have either) because he was trying to use the stop ring to limit the tower to what he believed was "just the right height." Once he gave up on that idea and moved the stop ring higher, he started getting the good results that I'm getting here. Good luck, keep experimenting. The results when you get it right are worth the effort.

Sounds like most of the horn speakers I heard at RMAF. You may be onto something!
