Topic: Mazzer Magic (6 msgs / 177 lines)
1) From: Jerry Procopio
I know this is going to be long and boring, but I need to share this 
with you people in hopes of finding an explanation.
A couple months ago I did a doserectomy on one of my Mazzer Majors.  I 
used plastic and fibreglas to cover the hole left where the doser was 
removed. (The metal one from EPNW was too small to fit).  I removed the 
sloppy paint job as well as the original paint and primer (not an easy 
job), then sanded, filled, primed and painted.  After removing the micro 
switch that lives in the doser, I realized that I needed to install a 
jumper on the terminal inside the machine body or the grinder wouldn't 
start.  I had to drill and tap new holes for the spout assembly since 
the holes didn't align with any holes in the grinder body.  I also 
purchased and installed the silly looking anti-static screen as well as 
new burrs.  I got a new short hopper and after installing little round 
felt pads that stick to the bottom of the rubber feet, the machine just 
fits under my cupboards.  The felt pads allow the machine to slide 
easily on the formica countertop.
I used some stale coffee to adjust the grind (in the garage) then 
brought the Major into the kitchen to his new home.  Next morning I 
eagerly put 3 scoops of beans into the hopper, opened the little trap 
door, closed it, then hit the switch.  In a matter of seconds I had 
evenly ground coffee.  The problem was, I had it all over the place. 
How do you spell S-T-A-T-I-C?
Well, I have been struggling, trying to find a method that would work 
without a mess.  I've ground into glass mason jars, measuring cups, 
plastic pitchers(the worst), paper bags, glass bowls, tin cans, filter 
holders - all with the same result - coffee all over the place.  Coffee 
would shoot out of the spout into the receptacle, then fly thru the air 
back towards the grinder and stick to the outside of the spout and clip, 
sometimes covering it completely.  Every morning I would have to sweep 
up coffee grounds from about a 3 foot radius around the machine. 
Needless to say, I was disappointed.
Finally, one morning I ground directly into my Chemex.  Hardly any mess 
at all. So for a couple weeks I ground into a Chemex filter, then dumped 
into the Technivorm filter.  This was the least messy method of all.
Now the twist.  I did my monthly maintenance, removing the burrs, 
cleaning them, taking the grinder into the garage and taking the 
compressor hose to it, then putting everything back together again.  The 
next few days the static cling was worse than ever.  Then suddenly 
overnight it stopped.  I mean completely.  I now grind directly into the 
Technivorm filter, in it's plastic holder.  No mess, no stray grinds 
clinging to anything.  I'm certainly happy about this new turn of 
events, but I don't have a clue what has happened.  I'm just calling it 
Mazzer Magic.
Does anyone have any ideas?

Jerry,
I have the same problem.  I think that when everything is super clean
in the Major you have an interaction between all of that nice brass
and iron creating static like crazy.  I have found running a ground
wire off my metal spout helped stop the static.

First guess, Jerry, is that the humidity has gone up in your house due 
to change of seasons :)
I know in winter time (in Massachusetts) I would get zapped from just 
walking across a carpet and touching a doorknob. Not so in summer. 
Humidity allows static to discharge less actively.
Interesting about the Chemex filter though.
While reading  I very first thought that these things usually grind into 
an enclosed doser, so coffee stays inside until you remove it.
My adapter is fully enclosed, but the inside of the container gets 
coated all over. Not so much on the top, but the sides are coated with 
grounds.
I suspect the filter was providing a nice ground plane somehow.
With my Major I could do nothing to keep grounds from spreading all over 
until I ground into a closed container.
There is always lots of low humidity, here in LHC.
Nice Tradition offering, I hope it gets some good use :)
I wrote that disclaimer when the list was alive with folks making all 
kinds of disclaimers. That was tongue in cheek, but we still should be 
careful when playing with 1200 Watts or better and 450 + temperatures.
So far I got a slight burn on my inner arm when I leaned into the lid my 
PGR when reaching over it while roasting.
I like to stay away from things that get that hot usually.
Nope still no gloves, and less than 2# cools quick enough with a hair 
dryer. Still the same hair dryer :)
BTW I took apart the first PGR today, the turbo oven part. Someone 
should come up with a better way to connect to the heating element.
The connections had all but oxidized away!
Guess it was not really designed to do back to back to back roasts for 
months at a time.
Yes, I will replace the connectors, and this time run 10 gage wire into 
the element also.. to replace the 18 gage it has been running on :)
Factory issue!
I should look up the date of when I first started using it... well over 
a year now.. November 2004 I brought it on line??
Seems like only yesterday..
Sorry this was so long :)

Some people say that monthly cleaning of this sort is not necessary.
Personally, my palate has never been able to detect a change in coffee
flavor due to grinder gunk build-up.   Keep the machine well-brushed and any
old nasty stuff is unlikely to slough off.  I switched from rice to Grindz,
and I do that every month----more as an act of faith than any
empirically-based need.
Just my FWIW

This is a multi-part message in MIME format.
The static (if I understand correctly) is possibly due to a combination =

else might be in the path.  One I believe may be getting positve charged =

the coffee and  involved materials, possibly try replacing the =
fiberglass material, maybe. Plastic and glass based materials don't =
always work well together.

I've had my Mazzer Major ( may be a ~20-year-old model ) almost completely
apart, with the exception of dismantling the motor itself. With just the
back (bottom) cover off the motor, the lead wire pigtails just disappear
into the windings with no starting switch, etc.
With the exception of the doser's plastic windows and the dispensing parts,
the grounds are only exposed to metal in the grinder. Oh, yes- there's a
small O-ring type foam seal around the exit port of the grind chamber, and
the grounds pass near it as they drop into the doser.
If there are any other plastic or glass parts installed, I think they're
aftermarket, not OEM.
