They probably put the sticker in the wrong place while assembling
I have a "Rocky" grinder that is still under warrinty, that is now grinding on #5 -im a little concered why the numbered postion is so low -(burrs are touching slightly on #4 zero point) and as i seem to remember the TWO other "ROCKYS" i viewed on display were grinding about position #11 & #8 - Im useing freshly roasted beans roasted approx on the 4th March from North Side roasting company. I use approx 2kgs of coffee every month (approx 18kgs thru burrs has passed)-Ive had the grinder just checked out while still under warrinty witch cost me $40 :( & there have been no MODS at all to the burr carrier housing. Why is the position so low should it not be grinding around or close to #10? and why are the burrs touching at #4 on the scale should it not be reading zero on the scale?.
My shot time is timed about 25sec for the standard double basket of my "ROCKY"
They probably put the sticker in the wrong place while assembling
My immediate response is that if you cannot safely wind the scale back to 0 the unit is faulty and unsafe and it should be re-calibrated so that it is safe to use. *It is obviously not safe to use. This is the sellers responsibility and it is at their cost. I think you would be well covered by the trade practices act - as the unit is not doing what it expected to do and is more importantly is unsafe to use.
Please disregard if this is irrelevant to you question.
Yes and No... * If *you have a thing with Zero being Zero.. Remove and re seat the decal... *TOriginally Posted by 71727F7F6A130 link=1268825943/0#0 date=1268825943
The hardware does not allow for little adjustments for Zero. *The top carrier can go on in 3 different positions.. *Absolute Zero will always be = Burrs touching.. *Zero on the decal can be any thing....
They are also a spare part.
1: Coffee by numbers does not work..
2: The Rocky does have a safety screw that should (not SHALL) actually stop you from taking it into a full burr on burr setting. It may still chirp see the links below.
3: The numbers mean little... They are an indicator..
If you went to use my rocky... Burrs touch at 20.. *On my other one 0 was the espresso setting....So what.. *
What I look for is the number of Clicks above Zero.. *Any thing else is just smoke and mirrors.
If the number worries you, ya can remove the decal *;) *Then ya just make a little pen mark where it needs to be for Plunger and for Espresso; PROBLEM SOLVED.
This has all been done and dusted only yesterday..
ANGERMANGEMENT firstly thankyou for your reply and also thankyou to the other pp that have replyed too!. I did read the posts b4 about the true zero point but do appreaciate your feed back ,but i was just a little concerened that if i do in future need to grind finer (one click less when the burrs are touching ) will i be doing any damage to the burr set?
Different beans & bean freshness do have have different grind settings dont they?
Yes... But if your grinding at ONE click above zero / burrs just *touching etc....Originally Posted by 32313C3C29500 link=1268825943/4#4 date=1268832563
Then if ya need to grind that fine. *Your Rocky; is not going to do it.. So why would you try to go finer.. *
The other issue; is the reason why you only ever adjust with the system running.. That way you hear it first and you dont crush teh burrs together.
1: ALWAYS adjust slowly and ONE click / step / little bit at a time..
2: If ya hear chirping etc... Why would one go an further ???? * Sorry I dont get it..
Lastly... If your grinding at one click above ABSOLUTE Zero.. You have a problem..
Where am I coming from..

1 - The numbers on Rocky are not at all calibrated to any standard, and mean nothing on their own. They are only relative to your own grinder. iirc, when I changed the burrs on mine the correct grind setting went from around 5 to around 15 or something like that... (just guessing from memory).
2 - When the burrs are "touching slightly" if you pull up on the hopper the touching will most likely stop. The same effect will take place when the grinder is actually grinding beans. The presence of the beans between the burrs will keep them apart. One thing to do is to use the teflon tape mod on the threads. They threaded portion of the burr carrier and matching threads on the grinder are of low tolerance and have a lot of slop when new. This mod takes care of that.
3 - The burrs touching slightly like that will not damage them to any extent unless it is allowed to go on for some time. Only the outer, flat portion of the burrs will touch, and unless it is a had, grinding noise, or as I stated, allowed to go on for some time, it wont damage the grinder.
4 - Rocky should be able to grind fine enough to choke any machine. If it cannot, there either is a problem with your technique (dose, distribution, tamp, etc.), the espresso machine is not working properly (too high brew force..?), or the grinder is faulty.
Personally, I recommend to anyone who asks in regards to espresso (and a few who do not) to bypass the Rocky and step up to a better grinder- I like any of the grinders by Mazzer or possibly the Baratza Vario (although I have no experience with that model). The Rockys price is not reflected in its quality, in my opinion.
ROCKY burrs touching
I have a "Rocky" grinder that is still under warrinty, that is now grinding on #5 -im a little concered why the numbered postion is so low -(burrs are touching slightly on #4 zero point
I may be misreading your post and if so I apologise.
I have had a look at my old Rocky again.
Something is very wrong. *Having to grind so close to the burrs touching suggests that the burrs are faulty or miss-aligned or there was a manufacturing problem with the lower burr too high on the drive shaft, or the cradle for the upper burr not machined correctly.
In an earlier post I said I thought the unit was unsafe. *I believe the Rocky is sold to a domestic market. So Consumer Protection would insist it must be safe for anyone to use. It would not be unreasonable to have a child or a not in the know partner or friend to wind it down in the natural course of use, or for the catch to become jammed in the open position . I have not every tried this but it may be possible in such a case that the burrs could lock and the unit to burn out, over heat or a short out.
Under the bean container there is a self tapping screw that is supposed to prevent the burrs getting into a locking situation. *
It may be okay for coffee snobs to play with a margin of danger. *But I dont think it is a good idea to make do when the unit as you say is still under warranty.
in relation as to the numbers on the grind setting.
if you unscrew the top carrier and look at the thread is there only ONE start point in the thread?
if there is 2 can you rotate the carrier and change the number for "zero".
i doubt that the thread on these is like that (two starts) but an old non coffee machine i worked with in a prior life had this issue and it had two thread starts on one bit and allowed you to change the "number" depending on which "thread" engaged 1st.
make sense ? to me it does .....
It would make sense; but no it is a very manual process and what the good ones might do is change the decal..Originally Posted by 48444D404049250 link=1268825943/8#8 date=1268878386
I have tried all three positions and as there are so many variables etc *as to stretching and general mechanical issues including worn burrs; Zero is not stable.
Guess what change it to all little marks and no numbers and every one would be happy.. *Coffee is not by numbers...
Yes something is wrong ::)Originally Posted by 4150484C5C44250 link=1268825943/7#7 date=1268873569
Not really.. Read the manual.. Disclaimers are thereIn an earlier post I said I thought the unit was unsafe. *I believe the Rocky is sold to a domestic market. So Consumer Protection would insist it must be safe for anyone to use. *
To make it 100% safe. Disconnect from the power and put in a box and place lying down in a locked *and secure place.
As it is; you have to depress the safety to change the grind setting...It would not be unreasonable to have a child or a not in the know partner or friend to wind it down in the natural course of use, or for the catch to become jammed in the open position . I have not every tried this but it may be possible in such a case that the burrs could lock and the unit to burn out, over heat or a short out. *
I would be more worrying about a vertically challenged person ( I do not discriminate agents kids) reaching up and pulling a bloody heavy object down on their foot *;D
Yes but there is Frito Pendejo to contend with *::) *See link at bottom.Under the bean container there is a self tapping screw that is supposed to prevent the burrs getting into a locking situation. *
NO never.. Risk management is about removing ALL danger!It may be okay for coffee snobs to play with a margin of danger. *But I dont think it is a good idea to make do when the unit as you say is still under warranty.
If under warranty - Return it.. *But no hard and fast assurance the service person is fully trained or understands.. *Often service is done by small retailers who do not know better...
Sponsors or retailers with a true service department and experienced staff.

Need coffee, meds and a peanut butter sandwidge ;D :D ;)
1 click from acceptable espresso pour to burrs touching does not sounds right, regardless of where the decals have been placed. Having not used a Rocky I cannot comment on tolerances, some people comment that Rockys burr carriers can be a bit loose. If the same thing were happening to me I would also be suspicious that something might be wrong, and wondering if perhaps there is some misalignment of the burr carrier causing problems.

but is more than possible with an underdose and/or stale coffee as well as decaf....
Ya know what [s]@mcm[/s]... opps 2mcmOriginally Posted by 114E56404B404C454546464E424D230 link=1268825943/11#11 date=1268882512
Ya got a very good point there.... Mine was always at about 4 clicks off Abs Zero with good beans... Stale of Decaf could be a contender..
Bugger... For got to read my own post on trouble shooting and forgot about the raw product and made assumptions.. *[smiley=lolk.gif]
