John. I read somewhere that tables for the grinders (with ball bearing ) have to be transported separately. Or it is urban legends?

The balls and cages were removed, wood placed onto the ways and the table were strapped down for transport. Unfortunately, sometime in the past it looks like the first one I’ve started cleaning wasn’t done this way. I can see round dimples in the flat way of the table where the balls have (I assume) bouncing in transport. Hopefully the second one is in better shape.

ball or roller, not urban legend although I suspect of the table is firmly strapped down things would be ok. When I've done it, they come out before transport. The issue as I understand it is that the table is held down by gravity so even small bumps cause it jump and the impact on the rolling elements causing brinelling.

brinelling

I like this terminology - is that the same Brinell that developed his own system of measuring steel hardness by pressing steel ball into surface ?

yes the same Brinell. famouse Brit engineer.
