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

I am not a user of the Vortex, others here can perhaps offer better advice. I'm trying to visualize the whole affair, and will try offering help through a good mechanical background.

I suspect that tower height adjustment, with the Delrin Locking Collar will be critical, in that the Wand doesn't come down too far under vacuum suction, thus causing excessive force upon the record.

From what others have said here, and the reason perhaps why Lloyd has complimented this product with Rubber O-Rings, is that the LP will actually sit ever so slightly above the Platter, and as the Wand goes down upon the LP, the LP supposed to actually come up towards the wand, to "meet" the wand, and thus by doing this, it is not the Wand's downforce pressure, but the LP actually coming up to meet the Wand regulating the degree of pressure, and by this, this must insure a certain level of adhesion-friction between the two which is not overly excessive.

Anymore friction-force between the two will no doubt result in possibly marring LP's, and may be also the cause of fluids being left behind as well?

Perhaps an accurate measurement of your slot, will let others help, as they relay to you what they find.

Again, I haven't used one, and may be in error with my thoughts, but I have probably hit the nail on the head with my above comments. Mark
Jamesbrianc, here's what I'm doing or have done:

Use a microfiber cloth to carefully clean all the accessible surfaces of the tube to make sure nothing is stuck to it from packaging and handling.

Seat the tube all the way into the tower if necessary to get the beginning of the slot above the lead in grooves of a sample LP. There apparently is some variability among the VPI towers and/or deck mounting position from what I'm hearing via some email correspondence with other users. (Remember, VPI has been manufacturing their RCM for 30 years.)

For my tower, I ended up removing the locator pin (push up from the bottom through the top of the tower) in order to push the tube further into the tower. Now, when looking inside the tower from the bottom, I can see that the end of the tube is pushed all the way against the bulge of the back wall of the tower. You may need to do the same.

Use one of your thin LPs and position the locking ring on the tower so the tube can drop down to the surface of the LP. Leave the locking ring at this position. Thicker records should then be fine.

Experiment a bit with orientation of the slot over the LP to get it as directly above the LP as possible.

On non-warped records, when suction is applied, you should not see any light between the tube and the surface of the LP across most of the length of the tube when looking from the side at the level of the LP. You likely will see some gap at the very outer edge of the LP. This location is always going to be somewhat variable due to the varying outer edge profiles.

When aligned, a single rotation should remove all moisture across the grooved area of the LP. If some moisture remains at the lead in groove or in the dead wax area, I use a clean microfiber cloth to wipe those areas dry if needed.

Wipe down the wand on the slot side with another clean microfiber cloth from time to time. I'm still playing around with the need for this and currently am doing it only after finishing a cleaning session.

I hope sharing these steps that I've used may be of some help.

Rushton (and Markd51)--Thanks for the feedback. I'll certainly fiddle with it more. If you (Rushton) haven't had similar problems, I'll assume that it's a set-up issue. Best,

JB, Please take the time for a couple of seconds to take a good ruler to the slot, and measure the slot length. Rushton can perhaps help, by confirming the slot size is the same (or not). Ya never know, yours could be slightly short, and this of course would make the differences. Again, hope this helps. Mark
Markd51--I just checked the slot length: it's exactly 8 centimeters. If that's shorter than the average, I'd certainly like to hear about it. Thanks,

JB Coleman
