Nice. So in order to move from 32 to 33.5 to 37mm drill needs to be moved on steps of that aluminium shoe. Could you please show how the two are fastened/connected together (the drill and the shoe base)? Screw? Thank you.

A do czego służą w czerwonej nakładce zakończenia w postaci tulei? Np. przy palcu wskazującym w kadrze 0:59 ?
