Parm it shouldn’t need that much torque though, it’s only holding the burr down so just a nip, the burr is turning clockwise so it should tighten the screw regardless.
So in this case there is something OBS wrong with it.
This shouldn’t happen, I’m lucky enough to have had in effect two duo and never had a problem with either but when you are spending any money be it £60 or £600 it should be right out of the box,
No manufacturer has immunity from this be it niche, acs, londinium,zerno they all have problems and it’s about working out how to stop it
I could write a whole list of issues from the above manufacturers but it’s not worth trawling mud.
