Anti-skate

Juliejoema,

try driving your car around a corner at faster and faster speeds and tell me what happens to the friction holding your tires in contact with the road. ;-)

Oh, my apologies Juliejoema. I get what you're saying.

Hi Sirspeedy,

I am wondering if you will have the opportunity to compare the Kuzma linear tracking arm with their new pivoted arm. I've seen the linear arm demonstrated by Frank Kuzma at a show and was quite impressed by the build quality (I also personally like Mr. Kuzma).

I am also interested in comparisons of linear tracking with long arms that minimize tracking error. While the long arms don't completely eliminate geometric tracking error, and don't eliminate skating force, they have an advantage over very short linear tracking arms -- the VTA does not change appreciably with changes in thickness of records. I don't change VTA for different records, yet, when setting up my arm, I noticed significant changes in sound from quite small changes in VTA. To me, VTA is a bigger issue than exact antiskating (or no antiskating).

Dan_ed, I'm not sure you meant for your car analogy to be applied this way, but here goes. Try driving a car in smaller and smaller circles. Which way, outward or inward, does the car want to go? I was hoping here to simplify anti-skate so the beginner could experiment. Yes, I know cantilever stiffness and other things have an effect. I also know(and I believe Conti's arm is unipivot also)that anti-skate is different on uni-pivot's. But, I was not trying to preach to the learned. We have kids getting into vinyl. We have people setting their anti-skate with the anti-skate records(which may or may not work), and thinking that their anti-skate is perfect. And that's not even mentioning azimuth, VTF, and VTA. That doesn't mean that I don't enjoy this discussion, but we also want/need other people to join us.

Yes, the car leans to the outside because of centrifugal force is pulling it that way. So why doesn't the car go flying off to the outside? Friction, the force acting between the tires and road surface. Overcome that and you skid out. But, I digress.

The Vector is a modified uni-pivot. It is that small bearing that keeps the pivoting in only 1 direction, looking from a line drawn through the bearing and perpendicular to the tonearm.
