Topic: Change those grinder burrs! (22 msgs / 432 lines)
1) From: Bob Brashear
Changed out the burrs on my Solis Maestro yesterday. Today, I 
re-experienced the discovery of great coffee. It really makes a 
difference. Finished up a pot of last years' Panama Gesha and am in heaven.
I work in metals (blacksmithing) and I'm amazed that tool steel can be 
affected by coffee beans. Live and learn, I guess. I'm going back 
through my notes later today. I believe I've gone way beyond the 50 lb 
limit some advocate here.

I picked up a comercial  Astra grinder AGS00? yesterday off of Craigslist
for $65.  It has titanium burrs which are suposed to be good for 1100-1700
pounds.  :-)

In some commercial busy environments that'd be a year at best. Don't assume
the burrs are sharp.

What was I thinking, at a modest 25LB per week that'd only be a year between
burr replacements! Definitely don't assume your $65 commercial deal has
decent burrs.

5) From: Bob Hazen
So it follows that a reputable house would be changing burrs every couple of 
weeks, unless they're of the titanium version spoken of below.  For some 
reason, I suspect that few if any of the non-artisan houses adhere to that. 
Could it be that the behemoth we love to hate and the local drive-up hut on 
the corner actually change the burrs regularly?  Perhaps it's my cynicism 
poking through again.
Bob

6) From: R Nepsund
I asked and the seller said that " a little mom and pop coffee place it came
from closed their doors rather quickly, so i don't think they were doing
much biz,"  after that she bought it from them and left it in her garage for
5 years never getting around to adding espresso drinks to her bar.
Considering the cobwebs inside it and the burrs being stuck from petrified
coffee grounds, I believe her.  I have pulled the doser and I'm fiddling
with making a doserless adapter.  I figure that if the burrs still have 1/2
their live span left ,at 3 pounds of coffee a month it should still last me
about 19 years.   I'll look into seeing if their is a way to check for
remaining life span after I have the doser problem taken care of.

7) From: Donald Varona
Is there a way to know the life expected of our burrs?  I've never heard
this mentioned as a metric for grinder lifespan.

Yes-
If you have to ask, Replace The Burrs. If you can't tell the difference, it
was a little early, not too early. It's an insidious situation, because the
burrs are wearing out from Day 1 on all grinders.
It's not magic- the performance starts getting worse the instant you start
using any brand new machine!
Cheers, Mabuhay -RayO, aka Opa!
Take notes.

9) From: Frank Parth
Hmm, so maybe the safe approach is to order new burrs for my 13 month old Rocky and replace the existing ones. If it 
makes a difference, keep the new burrs in. If it doesn't, then the old burrs were good enough to keep. Try this every 
two months until the new burrs make a difference.
At about a pound a week I've gone through maybe 60 pounds of SM's beans.

10) From: Eddie Dove
A good approach, RayO.
After having the Mazzer Mini for 8 months, a new set of burrs was
ordered to replaced the original set; the Mazzer Mini was purchased
new.  There were several reasons for this:
1. Gain the experience of changing the burrs and dialing in the grind again
2. Do the swap when I could schedule the time / purchase
3. See if I could notice a difference in the coffee
4. Have a good spare set in the event that I run a rock through the grinder
All accomplished.
Eddie

It's a great time of year to be going to Tahoe. Enjoy!
You may already be familiar with it, but if not, If you like
bar/restaurants with lots of good beer on tap and good burger baskets,
you might try the Bridge Tender, just across from the dam where Tahoe
drains into the Truckee.

Baratza is about to skip all that steel and go for ceramic burrs in
their new Vario grinder.
Ceramic is 10X harder than any metal/tool steel. I'm hoping all the
computer gizmos they put on it don't mess it up.
And, they shouldn't cost any more to manufacture.
It should be available in a few weeks.

If we have a coffee grinder with very thick stone burr ( like 2 inches
thickness for each ) , they will last forever or more, but with
precision???? Also, the burrs on our grinders can never be sharpened
and they just disintegrate and disappear.? Why don't they use
tungstene like on skilsaw blades or winter tire nails or a kind of
carborundum or zirconium-like synthetic diamond.? May be they are not
interested and they are in a kind of interest conflict.

Ivan,
Do you know if the new burrs will be compatible with older grinders?  I was
about to order a set of replacement burrs, but maybe I should just wait and
see what the new grinder looks like, instead.
Thanks for the heads up!

I wish!
I highly doubt it since they say that the Vario will be a flat burr, not
conical like the rest of their old line.
It may be the ultimate grinder with their powerful 480w motor and over 150
grind settings. Matched with ceramics that hardly ever dull, it could save
$$ in the long run. The ceramic burrs are larger too, meaning more grinding
area and longer life.
It should add up to better brew.
But, I'm still holding out for that Romulan Molecular Disruptor grinder. :-)
