A new way of adjusting anti skate!

I was looking at the Wallyskater, a $250 or so contraption used to set anti skate. https://www.wallyanalog.com/wallyskater  It is reputedly the most accurate way to set anti skate. Talking about fiddly. 

The appropriate figure is 9 to 11 percent of VTF. So if you are tracking at 2 grams you want 0.2 grams of anti skate.
My Charisma tracks at 2.4 grams so I should set the anti skate for 0.24 grams..................................Bright light!.
I readjusted the Syrinx PU3 to zero so that it was floating horizontally. I set up a digital VTF gauge on it's side at the edge of the platter so that the finger lift would be in the cross hairs, activated the anti skate and was easily able to adjust it to 0.24 grams. I started at 0.18 grams and just added a little more. Whatever you measure the anti skate from it has to be at the same radius as the stylus. If you do not have a finger lift at the right location you can tack a toothpick to the head shell and measure from that. As long as you have the whole affair balanced at zero you will be fine. Added cost $0.00 as long as you have a digital VTF gauge. 

I would not buy stock in Wallyskater.

But I wonder if in at least some cases, the manufacturer marks the dial as a guide only.

Agreed Lew, it is just a reference scale from the manufacturer

 

I am very impressed on my analog rig sound, the DL-301 although cheap it is incredibly good, rivals my digital, better soundstage

@lewm I still not get it how the OP goes about doing this floating arm. Is he attaching some kind of string to the headshell and then zeroing the digital scale with no AS and go from there? 
Every tonearm has some degree of AS even when the setting is at 0, so even the smallest angle on the string would affect the value.

I use Analogmagic as my baseline, then move from there.

I believe that with either the Wallytractor (which  has the limitation of not having all the spindle to pivot arches) or the Smarttractor and Analogmagic I can set the cartridges very easily and precisely.

what are your thoughts?

The SME V antiskate dial has a recommended number to match the VTF, which according to some things I’ve seen out there equals about 10% of the VTF in actual force. YMMV…

Tangential fan for decades, now....

Skating is something best done on a rink; anti-skating should be relegated to the name of an aunt....;)

Lew it is headshell offset angle. The reference is to the arm's pivot not the record. The equation works fine. The variation is in the kinetic coefficient of friction which changes with groove velocity. The recommended value is 9 to 11%. I just round it of to 10%. 

You can not hold the gauge vertical. All that I tried gave unreliable readings this way. I used a 1 to 1 pivoted arm to change the force from horizontal to vertical. The scale sits on the platter as usual. The floating arm which is drifting outward because of the antiskating force is then located against a pin in the vertical arm of the 90 degree lever. The force is transferred to the scale and you have a measurement. The lever arm should place some downward force against the scale which you cancel out with the tare button. The quality of the bearing is critical. Cheap bearings out of router bits will not work. Ask me how I know! I used a tiny, oil free, ceramic ball bearing. You want a scale that measures down to thousandths. I'll email you a picture when I get a chance.
