After my last attempt at drowning the Rocky by pouring the water in there rather than down the Gaggia Baby, my "zero" point where the burrs start to catch is -10 (I took it apart and it obviously didn't quite go back the same
).
SW (Thinks She) MBO is the espresso drinker in the household and has been away for a week, so I haven't had the Rocky on the espresso setting for a while. Obviously when she gets back from her holiday in Brittany she wants one of my nice coffees
So, I sort it all out, measure the beans, set the grind and off I go. Hmm, what's that funny noise - must be the "handle" vibrating in the metal holder for it on the Rocky, I'll hold it a bit tighter. Nope, noise hasn't stopped 
Oh bu**er - I've got the setting on the Rocky wrong - the noise is the burrs catching!
Took it apart and the burrs seem to be OK...
Anybody fancy a job as a barista in Rotherham?
