would it be possible to know. the belt tension. and should you leave some room so that you can tighten it when it gets loose over time ?
it would really help if you made a video to show how much force you should use and how it should Glide
how smooth Should the root move. and should the bearing have any influences or artefacts in the movement pattern
I think you should add how many newtons you can tighten the u bolt since some people have access to tork wrench and as a work injurd I get chills down my spin seeing you tighten with a plaer on the picture.
