Hi Andrey,
Sorry but I did not get well what kind of experiment I should make.
My statement regarding the mag guiding is that once you have tuned well the wire and the mag dimension and gap between the wire and the mag, the arm wand react as follow:
1) The mag in default keep centred the wire track, but also allow the micro movements due to the eccentricity fo the record in plus or minus with the tendency to return to center when the record turn centred.
I do not understand well ( sorry for my slow understanding of things ) how a side rigid contact cam allow the plus and minus off centred of the record can keep the cam in contact with the bearing. In my mind should loose contact depending on the off centred of the record, being not a fixed swing system but a side contact. May be I am wrong and if so I have no problem to accept.
Regarding the inner position of the cam comparing to the original LT TA I also could not imagine the advantage therefore I asked.
Thank you and best regards
Adelmo

Now the answer is up to you and Carlo. The ball is in your court.
No thanks - not mine
In the past i've done a couple of Birch geometry tangentials, the belted Rabbit and the Doug's dual pivot 3DToy, but I've always stayed away from "cam driven".
First because their official geometry is a trade secret, and i dont' know how to design it correctly; second because I'm not convinced by the cams: the magnetic ones because I still remember of Earnshaw, and the rigid ones because they are rigid and can bring problems on warps and eccentrics.
My congratulation, Andrey, are deserved to a novelty (rare, nowadays) in this typology: i like new things, and I'm already happy if are not worse than the old ones.
