Topic: Out of plane rocky burrs (4 msgs / 68 lines)
1) From: Mike Koenig
Since there is quite a bit of Rocky experience on this list, I'll
throw this question here..
I've come to the realization that my burrs on my Rocky are
out-of-plane with each other.  I've started noticing my grind has a
few "rocks" in it,  larger chunks than I'd expect, along with fines
(mind you, I mostly grind for espresso).  I recently replaced the
burrs in an attempt to fix it, but no luck.  When I turn it so the
burrs touch, I get an intermittent sound of metal touching metal,  and
if I paint the outer edge with a marker, and then run it with the
burrs touching,  both burrs seem to show a side with no wear.
Does anyone have any experience with a DIY repair for this?  Something
along the lines of shimming the burrs?  If it turns out I need to send
it in for repair, I'll probably just look into getting a Mazzer.
thanks in advance,
--mike

Did you let some ex-baggage handler ship the grinder for you?
Which of the burrs had the asymmetrical marks on it?
It is possible that the driveshaft of the spinning burr has bent, so that
the spinning burr has a high spot. That would show the wear spot in your Dye
Chem, or the shiny wear pattern on the unmarked burrs.
With both burrs showing the asymmetrical wear pattern, Rocky is definitely
SNAFU. The driven burr likely has a bent shaft, and the stationary burr has
a high spot that could be shimmed.
I don't even think Vicki's Rocky took it that heavy, even with the sudden
change in acceleration (jerk) when it hit the floor!. Rancilio will charge
about $350 to fix it for you. It'll look like new, too. Make your appeal to
the Diety...

It's a Mystery.

Deity hates me- so what else is new.

Nope, my burr assembly was fine when my Rocky became Pebbles--everything 
else was broken. The fellow who repaired my machine said that 
replacement parts (other than the usual culprits) are hard to come 
by--have to be special ordered and can take a long, long time. My repair 
shop said they took parts off of another (new) machine for mine whilst 
they waited for the parts to come in. The repair bill was $250ish.
