Topic: my zass find (12 msgs / 283 lines)
1) From: John Casey

I recently won an ebay auction for a zassenhaus 156 (nearest match I can
get from the pix I've seen), but it was in need of cleaning when I got
it. I found a copy of Tom's maintenance instructions online, and
followed that to clean it up, but it sort of left me wondering whether
this thing needs a little more TLC. I know next to nothing about this
stuff, being an extreme newbie to the roasting scene, and could use a
pointer or two, if someone can spare some advice... :)
I've noticed that when I have the knob set at about the halfway point, I
can only hear the burrs rubbing for part of the turn. To me, it would
seem that this on-again, off-again action would lead to uneven grinds.
I'm fairly sure it's caused by play in the bearings/bushings/whatever
along the crank-shaft...but I still don't know if this is bad.
Are there any places online or otherwise where I can go to find out
about maintaining this thing? Are there other things I should be
concerned about? It was a good buy if it's in decent working order...
BTW, I've found this list to be an unbelievable source of education, and
I've learned a lot from you all in the last six months. Thanks for the
great discussions!

      I have three Zasses and none of them make uneven contact.   You 
are not the only person who has reported this in their Zass.  It makes 
me believe there may be a quality control problem that I have not 
experienced.   I guess I may have to back off my enthusiastic 
recommendations in the future.  Sorry I can't help with the alignment

If your in the SF bay area I do have a small shop in the basement we 
could take a look at it.

I missed the original post - but I agree with you Jim. I have a DG169 and m=
son also has a 169 and we've had no problem with uneven contact. I would be=
more concern about why the unit was for sale on E-Bay than questioning the=
Zassenhaus quality control.

I'm sure it's not the brand, but the fact that I bought it on ebay for
$28, that's more indicative of the problem...
oh well, I'll see if I can fix it.

Thanks anyway. :)

Unfortunately I have had two Zass DG 169's and both have uneven contact -- 
creates dust and not suitable for espresso.  I am not a Zass basher, however.  I 
just love it for trips and when I am in the mood to grind for drip. I have no 
doubt that an even Zass would be great.  Only wish I had one.

Not that far, if you have a personal Learjet.  If you did you could 
probably hook up one of those rotisserie roaster close to the exhaust 
and roast while you go...

...or just buy a new zass! :)
I might look at taking this one apart, to see if I can find a
replacement bushing...anything I should be careful of?

alright, I took the grinder assembly off of the box, and the whole
mechanism looks subtly different from the pictures here:http://www.coffeegeek.com/forums/coffee/machines/74643so I'm lead to conclude that either (a) this is not in fact a Zass, or
(b) it's such an old model that the grinder assembly has changed (like
with the advent of plastic, for example!). Anyway, upon turning the
crank, I noticed that the inner burr wobbles, like the shaft is bent...
also, I took a closer look at the inner burr, and noticed a sizable
chunk taken out of one side! I dunno who decided it would be good to
grind a chunk of concrete in there, but it's hurting.
So, I guess I'll chalk this one up to experience, and start sticking to
"caveat emptor" a bit more closely.
BTW, just ordered a shiny new knee mill from SM, so this won't be a
problem again.
Thanks for the advice/etc.

I didn't read this until after my "morning thoughts" post. I now think
most hand grinders are self centering when the beans are added and this
play is normal. I would use it and if it works you are OK.

I'd like to second John's observation. I have a brand new knee mill (about 
2 mos. old). I'm having considerable problems with it. It coarsens with use 
and when attempting to adjust the burrs I frequently turn the adjustment 
upwards of nearly 2 full turns to see any difference. Once I get the press 
pot dialed in, I then have to play around again to get it close to the 
espresso adjustment again and it never seems to quite make it 
(frustrating..). I'm actually going to take the time to take it apart this 
weekend and see if the mechanism is sitting loosely instead of properly 
bolted down inside. I'm hoping that such is the case.
I've been less than enthusiastic about the "boulders and powder" that seems 
to come out mixed at some grind settings - no I don't think I'm being fussy 
when there is probably 20x difference in the size. The only thing I can 
think of is that the mechanism has slop in it causing it to grind close on 
one side and at a greater distance on the other side. I'm hoping that I'm 
not going to have to pay to ship it back. I'm going to be definitely peeved 
if I'm left with no grinder for my coffee!
