Topic: Rocky grinder question (8 msgs / 227 lines)
1) From: Steve Carlson
I recently got a Rocky Ranchilio grinder, which I really like.  It has
dramatically improved my cup. I have a question about grinder settings.  I
am little confused because the settings seem to be the opposite of what the
manual indicated, and I want to make sure I am doing this right.
The coarsest grind I get is when I turn the barrel counterclockwise and get
the little triangle indicator not quite to "0", and there is a clunk telling
me it has gone all the way.   (the zero remains to the left of the triangle
indicator).  The grind is pretty coarse at this point.
If I then turn the barrel clockwise, and really torque it, I can get the
triangle indicator up to the 40.  The 30 is coming into view (to the right),
but I can't turn the barrel to get to the 30.
The grind at 40 is pretty fine, probably about the coarseness of ordinary
granulated sugar.  I thought the grind would be finer than it is, but I am
pretty happy with the results (although I might want finer if I get serious
about making espresso).
Is this mode of operation consistent with your experience?  Is there a way
to get the setting down to 30, or 20, or 10?

If I remember right, the collar position is a bit arbitrary. To find true
zero, rotate to finer and bump the on button. Reapet util the burrs just
click against each other. Then, back up 2 - 3. Thats zero. My espresso
setting is ~10 above that, and FP, AP, etc 20- 25.

Without going in and disassembling mine, I can't say for sure. But it sounds
like something isn't assembled quite right. If you're somewhat mechanically
minded, you might want to take it apart and check it out. It's not very
complicated.

Sounds like the barrel was attached about 2/3 of a turn off, so what 
you're seeing is a large "calibration error." Turning the barrel 
clockwise brings the burrs closer together, counterclockwise takes them 
apart, so Rocky's working OK. It might also be that there are beans or 
pieces of beans causing you to use effort to turn the barrel and to 
think that it is as far as it will go when the burrs are not yet 
touching. I think that some recommend adjustments be made with the 
grinder running, but I usually turn clockwise, hit the on switch 
momentarily, turn again, and repeat until the burrs touch. Once you've 
reached this point, you can remove the three screws in the barrel, 
remove the barrel (it comes straight up) and reposition it so that the 
zero indicator is in front--or as close as the screw placement will 
allow. When you have the barrel off, you will notice a single screw 
protruding down from the bottom edge. This limits you from making a 
full revolution. This is probably what you are encountering at 40. I've 
heard it is OK to remove it if you want, but I've never felt the need. 
Hope that helps.

If the indicator band is really off, you can order a new one and put it on so that the grind is finest at true zero. 
That's what I did when I replaced my Rocky's burrs. I ordered a new dial indicator at the same time, peeled off the old 
one and replaced it with the new one after I found zero. It's very easy.
You can get it from espressoparts.com

how fine is the grind for you all when you take it to the finest?  In
relation to normal granulated sugar, is the grind much finer?

I'm not sure I understand how you are getting what you are getting.
I have true zero at about 5. That is where I hear metal on metal. A clockwise turn makes the grind closer to zero and therefore smaller. Turning counter clockwise makes the numbers go up towards 40 and therefore a larger grind.
I can walk you through this but I guess I need some more info. You can write me here...or off list and we can talk on the phone if you'd like.
Where is true zero? it may be that the factory put the decal on wrong or that you have over turned a revolution. However...there is a screw on the bottom of the hopper to prevent overturning past zero.
Let me know....as you turn counterclockwise the burs separate and essentially should be easy to turn. As you go clockwise the burrs get closer....on mine since the true zero is 5...if you turn past that to zero...the hopper is harder to turn.
If its screwed up....the hopper can be taken off...burrs set to zero...and hopper replaced.
To give you an idea of my settings...
true zero 5
turkish 5-6
espresso 7-9
aeropress 14-15
moka pot 15
vac pot 15-20
french press (i switch up) 35-45

Steve,
Turning the hopper clockwise (if you are looking down at the hopper),
should bring you to lower numbers, though you might be crossing the
zero point.
The first thing you need to do is find your "true zero", which is
where the burrs touch.  Run the grinder for a second, then stop it,
and as the burrs are coasting,  turn the hopper clockwise, slowly,
until you hear a metallic sound, which is when the burrs are touching.
 This is true zero.  About 5 divisions counter clockwise from here is
a good starting point for espresso.
If you are off by 20 divisions or so, your hopper may have been put on
2/3 off from where it should have been.  Set your burrs to "true
zero", remove the 3 screws in the hopper, and take the hopper off.
Then put it back with zero as close as possible to the arrow in the
front.
If the hopper was put on wrong, there is a screw that will stop it
from making a complete turn around to the zero point, so you might
want to set your zero with the hopper off (just keep all fingers out
of the throat!!)
Let us know how you make out.
