Peter, You know more about this stuff than I ever will, but I do know a little about the JMW arm having used one for a few years. The wire twisting thing gets way over blown. I agree if you twist the wire either way one revolution, it is too much. However, if you plug in the wire with absolutely no twist with the arm in the rest, the spring action is now almost perfect in that as the arm rotates toward the spindle, the spring (wire) is tightened and this applies a small amount of force outward in the right direction. I am sure that some will see this as imperfect as the force gets greater closer to the spindle and is decreased toward the outside of the record, but it works out to be a very small amount of anti-skate being applied, and as you said, skating varies and less is more.

As I mentioned earlier, you can test this small amount of torque by unweighting the arm until it floats level above the record surface. Holding the stylus over the innermost grooves, carefully let the arm go. It will float toward the outer perimeter of the record. You want it to float gently rather that furiously.

As far as twisting the wire, this is too often done grossly. The way to "twist" the wire is to hold it straight up and gently twist or untwist the wire. Plug it back in straight and with a nice arc - no curly Qs. I didn't discover or make this stuff up. It is somewhere in the archives described by HW. I read it years ago. He doesn't post around here anymore unfortunately.

If what I have described is not precise enough for some folks, it is an excellent starting point to adjust from with your or VPIs add on devices.

Anti-skating is overrarted, most good arms don't have any provision for it. - jihad 16:21:56 01/20/12 (9)
