@ Dover , your statement about azimuth is incorrect and misleading. Indeed there is azimuth adjustment on the Korf arm. Better to own one before making such a statement.
I made the statement because I asked the designer about the non offset bearings & azimuth when the 1st preproduction run was in process.
If it has azimuth adjustment then that is different to what I was told by the designer in an email he sent me.
Notwithstanding that, with non offset bearings when you change VTA the azimuth goes out and needs to be reset every time you adjust VTA.
