JahLaza making me nervous about going near it now! I guess I’d have to actually do the marker test on inspection to confirm this wouldn’t I?
No need to be, think about 2 rotating disks and the types of misalignment, a marker pen simply shows you rub points.
Below is a work in progress, it’s unfinished and I don’t know if I will ever get round to finish it. It takes a grinder where the upper burr is fixed and as part of the adjustment process is not rotated (e.g. K3 or ECM grinders etc..). I started this a few years ago. At least it gives you some things to consider. |Take it all with a pinch of salt, I can’t remember what comments I was going to put on the last image and I can’e remember if it replicated some stuff in the first image….enjoy
