Subject: Rocky - unknown part
I decided to clean Rocky. Removed the hopper and underneath, screwed
into a hole next to one of the hopper screw holes (protruding downward)
is a course thread, screw (approx 1.5 in long).
1. What is the purpose of this screw? (Can't find it on the parts
diagram)
2. It is bent at about a 30 degree angle? Is this correct?

I had run some REALLY oily beans and wanted to get that residue out
before it stuck to everything...but cleaning can't hurt, Dave. Anyway,
I did remove the majorly bent stop screw and now I can unscrew the
upper burr without having to remove the hopper, etc.

Although Rocky is a lot of grinder for the money and will last a
lifetime, it is not the best designed grinder in the world. The
terribly designed detent spring on the doser is an example. After
breaking two in about a year I made my own which has lasted years.

As for the design as it relates to cleaning, on the top side of the
upper burr carrier there are three depressions designed to assist in
bean feeding. Unfortunately these tend to gather a lot of coffee
debris and oil. They fill up and slow the feeding of the beans and
exacerbate the problem of blockage necessitating a rap on the side to
get things moving again. The grinds ejection arms on the lower burr
carrier also build up grounds that sit around and then can end up
breaking off and ending up in the portafilter. Much the same can be
said for the area around the acorn nut in the middle of the lower burr
carrier.

The frequency of cleaning should be regulated by amount of use and the
level of oil the beans exhibit. Two or three times a year I will
remove the upper assembly and clean out manually with a chopstick or
similar. Otherwise I like the way that "Grindz" works. About 3/4 - 1
scoop of them in a coffee measure does the trick so even a small
container should clean the grinder a number of times. I have not tried
rice so can't comment. Grindz are not cheap, but the benefit of this
method is that you are not wearing the threads of the burr carrier
assembly by unscrewing it repeatedly.

All other things being equal, a bit too clean is better than a bit too
dirty. It's odd that so much effort is placed on using fresh coffee
to get the best taste possible, but there are those here who seem to
think that cleanliness of the espresso machine or grinder (or lack
thereof) does not have an effect on flavor.

Nice idea. I'll remove it and mail it off to Daveb.
I realize Rancilio's intent with the stop, but, if one is paying that
little attention, rotates the hopper 360+ degrees,( the zero point is
now actually 74 or something which should make for really fast shot
timing) they should have their tamper taken away in a ceremony similar
to the British stripping rank.
Thanks for the tip

That would only work if you were in the habit of having your tamper sewn to
your uniform with a little thread. Surely your tamper is properly attached?

It should not be bent. I removed mine to allow the removal of the
hopper (and thus, the bottom burr, giving easy access to the grinding
chamber) without using tools.

Thanks. When I reassembled Rocky, I realized the function of the screw.
I've only had Rocky for 7 weeks and have never run him without the lock
engaged. Maybe daveb knows since he repairs Rockys. Daveb are you out
there? Dave, Dave......
Thanks again

If it is the one I am thinking of, it prevents the hopper from unscrewing
completely... Have you ever run the burrs with the grind adjustment
unlocked? That could explain the bentness!
