Hi Marek,
When building a Schroeder clone, you have to use the right diameter/stiffness thread, otherwise there will be to high a difference between the skating compensation at the beginning vs. the end of the record.
I believe I posted before that in my arms there is a 2% increase in antiskating force towards the record end, that is without taking the resistance/springyness(hope that is a real word...) of the wiring into account.
With proper dressing of the wires you can achieve a very even antiskating figure across the record. Still not perfect as there are other factors like the varying tracing error(perfect skating compensation does not follow a linear function), different vinyl formulations(with varying friction coefficients) and the influence of the modulation/groove velocity.
Summary: skating force compensation will always be a compromise, but at least the best implementations will not introduce friction or resonances.

Greetings from Colorado,

Frank Schroeder

Hi Frank,
I like your design very mach thatís why I cloned it. Thanks for your intellectual contribution.
The first thing I did, I tried different thread diameter. My magnet is drilled 1/32Ē.
I also tried to braid the tonearm wire clockwise and counter clockwise to combine its action with the thread action but it didnít work. I realized that with your design no tweaking is going to produce the antiskate force decreasing towards the recordís end. As you said even your best afford produced 2% increase.
On my first clone antiscate is much better then on my commercial tonearms. It is good enough for my inexpensive cartridge. On the second clone (the upside down design, which is my reference tonearm) I would like to achieve antiskate force DECREASING towards the record end. It is important to me and I am working on additional magnetic compensation system for the tonearm.

I have installed a simple antiskate correction on both my DIY tonearms. It works well and makes noticeable improvement to the sound.

Merry Christmas everybody
