Hi Niffy.
Thank you for your reply. I also admire your work.
Let me first digress from the topic. To my great regret, I have to communicate with you through an automatic translator. The translators on my phone and laptop often give completely different translations,you can see for yourself by looking at the screenshots and doing the reverse translation. Pay attention to your nickname. Which one is correct? That's why I will write in short, concise phrases and, sorry, you will not be able toenjoy the beauty of the Russian language. However, this will not give the automatic translatormany chances to greatly distort the meaning of what is written.
A few words about myself.
I am a pensioner, I am 67 years old, I live in Krasnodar. I listened to vinyl most of my life, then CDs, after retiring I got into vinyl again. I am a DIYer and I like to remake record players in my own way. A year and a half ago I got interested in tonearms, then I accidentally came across this forum. I read this thread and the thread "Angling for 90° - tangential pivot tonearms". At this stage I am working on tangential pivot tonearms of my own design, and I am also closely following this thread. I am a meticulous person when it comes to technical details, so please do not take my questions as criticism, they are of both purely academic and practical interest to me. In several of my posts I will explain why I came to this topic and not to the thread"Angling for 90° - tangential pivot tonearms" and ask questions that I did not find an answer to in the thread, or maybe I missed them by accident.

Hi Andrey,
This thread and the angling for 90° thread have both become very long. Finding the information that you are looking for can be difficult. Especially if you are using a translation program. There is a lot of excellent information buried in them. If you can't find what you are looking for or need something explained please ask. We all like an engineering challenge and love to share the knowledge we have gained.

Hello Niffy and all forum participants.
I will continue.I will have to say a few words about the path that led me to this topic. At the beginning of my path as a tonearm builder, I conceived of building two ordinary tonearms of my own design, a simple and a complex one. However, after building a model of a simple tonearm (in the photo) and listening to it, I abandoned the further idea. Why? It was a short straight tonearm with the stylus not reaching the spindle. This is an amazing tonearm, it completely turned my understanding of the mechanism of extracting truly full-fledged sound from the groove of a vinyl record upside down.If earlier I was engaged in improving the anti-skating mechanism, I made designs with an ideal characteristic and believed that it worked perfectly, then after listening to many records with this tonearm, I realized that it is impossible to create an anti-skating that would automatically change the anti-skating force for all records. As a result, with a single adjustment of the anti-skating, on different records, sometimes on one side of the track, sometimes on the other, there is an undercount of musical information. This manifests itself in a lack of high-frequency sounds in one of the channels.
In the short straight tonearm I built, there is one point with zero error, and at this point the skating force is zero. And at this point and near it, I heard how music should sound with a full signal reading from both sides of the groove at the same time. This really struck me. I listened to many records in the area of the zero point and immediately compared them on a regular tonearm. And it turned out that on a significant number of records I listened to, there was clearly not enough high-frequency sounds in one channel or another, and on some it was the same.
This new understanding of the detrimental effect of the rolling force on the completeness of readingof sound information from both sides of the grooves made me turn my attentionto tangential tonearms.
I thank all my colleagues who read my introduction to the end.
In the next message I will tell you about the question that worries me and to whichI have not found an answer.

Hello Andrey,
Welcome to the exciting world of tonearms. This thread is about linear tracking tonearms, where the arm is tangentional to the groove at each point of stylus travel, and the pivot follows the stylus movement.
The other thread is about pivoted tangentional tonearms, where the arm is similar to the conventional pivoted arms, completed with a clever trasmission that makes the arm tangentional to the groove at each point of stylus travel.
It is difficult (for me) to decide from your photos, which category your arm belongs to.

Hello Icsaszar,
I think Andrey's tone arm is a straight tone arm with so-called underhang.
