I have a question about burr alignment (in my case EK43, but would apply to most grinders I’m sure).
First burr to align is the static burr. After employing the marker pen/shimming technique, we get to a point where the marker pen is wiped clean across the whole face of the static burr.
Now, we move onto the moving burr. How is it possible for the moving burr not to be parallel with the static burr if it has wiped off marker pen from the whole of the static burr? If it was at a slight angle (i.e. not aligned), then it would only meet the static burr at a certain point and the marker pen would not have been fully wiped off.
The curious thing is that the moving burr does indeed appear to be not yet aligned, i.e. when employing the same marker pen technique it appears to require shimming.
I just cannot work out why or how this is possible!
