Topic: Sharpening Burrs on Zassenhaus Grinder Eddie Dove (12 msgs / 243 lines)
1) From: Jeremy DeFranco
Eddie,
      I noticed on Tom's Zassenhaus tip page that he says there's no need to
sharpen the blades...Metal's rock solid. Did you see this yet??
---Friends and family,
Has anyone sharpened or have ideas on how to sharpen the burrs of a
Zassenhaus?
Thank you in advance.
Eddie

My friend has one and its producing a lot of fines.  He got it off of
ebay from Germany.  I told him I would look at it and see if I could
do something with it.  He also said he's got it set to grind as course
as possible.

There's got to be some way to get them sharpened, maybe a local machine shop
could help?

If he is set to grind as course as possible, that in itself could be 
the fines issue.  The beans are breaking and producing fines instead 
of getting ground.  Even sharp, (assuming the burrs need help), a 
loose setting can have the beans moving too much in the hopper and 
just cracking.  Have you actually examined the burrs to determine 
what they need?

Thanks, Sir John.
He is supposed to bring the grinder to work today.  I will take a look
at it with that in mind.

I don't own, in fact have never handled a Zass. But I wonder if acid
sharpening would work:http://tinyurl.com/253s68It seems like it would.

Dave,
That is a fascinating read.  I may have to try that on some old mills
I have for decoration just to see how it works.

I got a Zass from someone on eBay and it doesn't grind any better than 
my Bodum Antigua. So there are some duds out there. I'm not sure if 
sharpening the blades would improve the evenness of the grind.

Good call Alchemist John,
My friend brought the grinder in and I brought him some coffee today
(Ethiopian Sidamo & Columbia Peaberry from Ginny that he really
likes).  First thing, I pulled out the drawer to look inside and
jerked my head back, "Have you been grinding black pepper with
this!?!?!?!"  "No!  Is that what that smell is?  I thought it was the
smell of the Mahogany!"  We talked about Minute Rice ... lots of it!
Do I need to take his mill apart and lightly sand the inside?
The uppermost part of the burr looked like somebody tried to grind
rocks with it, but the rest of it looked pretty good.  I ground some
coffee and the grind was all over the the place - really uneven - some
pieces looked to be the size of 1/4 of a bean.  I adjusted it and
ground some more, and adjusted it and ground some more, and I found a
setting that was fairly course and just shy of starting to be a bit
uneven.
All the while I was placing the grounds on sheets of paper.  I
motioned to dump into the trashcan and he about tackled me!  He really
loves my roasted coffee, which I consider a great compliment.  He is
the only person I know personally, on a daily basis, that can taste
and discuss the subtle flavors and nuances.  Anyway, he left the
office snorting a Styrofoam cup full of ground coffee.
Thank you to everyone for giving me ideas.  I am not that familiar
with the hand grinders and you folks helped me help a friend.
I still think I will have to try the acid sharpening on my files
though ... especially my favorite one.
Respectfully,
Eddie

I bought an antique Armin Trosser grinder non eBay.  It too had been =
used
for some funky grinding - my guess is that an artist had used it for
pigments.  I cleaned each burr with a pointy tool, ran a bunch of rice
through it, and now I use it to grind spices.
BTW - it works GREAT for grinding up huge amounts of spices for BBQ rub. =
 If
I need a half-cup of ground black peppercorns, it is the only tool I =
use.
It works equally well for grinding large amounts of coarse sea salt into
powder.
The moral of the story is that if you are buying a grinder on eBay, =
inquire
as to the condition of the burrs!

12) From: John Moody
I assume you are kidding, but in case anyone is actually thinking of
following those acid instructions, think twice.  They suggest adding water
to acid; bad idea.  Further into the text, that is mentioned but I worry
some might not understand the danger.
John
