Taming the wild Major!
peterz
There are a lot of old Majors out there for sale.
Mazzer sold a lot of them to *$, and they are being replaced.
I got what I consider a good deal on one, even though it is old and beat:(
It came with no doser, no hopper, and kind of a plate over the front with a copper fitting attached with silicon sealers:3


This is what it looked like when I got it down to basics:

users.rraz.net/peterz/major/new1.jpg

You can see it is really beat :(


It looks like it may have seen duty as medium in a rock crusher. s:7 s:8

I can not imagine how it came to look so mistreated.


It barely worked when I got it, but the vendor sent me a new start capacitor, and new burrs Grins:1

Also, the hopper fom my Mazzer Mini fits almost perfectly.

Next problem was how to handle the grinds? s:6


It pushes out lots of coffee.


First I tried using the set up it came with, but grounds went EVERYWHERE!;)s:8

So I tried as a backup, a large SS mixing bowl, and catching the coffee in a 1 pound bag s:8s:8c:1

More coffee went on me than went into the bag, and lots went over the walls and floor to.:@:@c:2

Before I grind any more, I need to harness this beast. s:4

I tried copying some of the adapters I have seen, but no luck. Coffee still sprays all over.

So I happened across a SS canister that just fit the doser curvature.
It gets held on with a spring (womans belt)
from a thrift store:

The canister is just the right size to hold a pound of ground s:2B)

and covers the whole area where the front plate was.


It had a clamp strapped onto the canister, but it was in the way.
So I removed it and just kept the plastic lid with the silicon washer.

Here is a picture of the inside, you can see how I cut a square hole with my Dremel to match the Mazzer Major outlet.

Now the ground storm is all contained! s:1s:2

Nothing gets out while grinding Grin

The wild coffee spreading Mazzer Major has been tamed s:2

Peter. Want a hoppe? I have a hopper from my MM that may fit. If you'd like it, it is yours. If so, first measure the inside diameter of your inlet so I can make sure it will fit. Dan
peterz
HI Dan,
Thank you very much for your generous offer.Grins:1

The neck inlet on the Major is ~ 2+5/16 inches.
The neck on the Mini is ~ 2 + 1/4 inches.

btw, your pm box is full s:3 s:8s:8

Pete, that thing is cool--where can they be found?
peterz
They sell a lot of grinders like this on ebay;

could be better or worse condition:|

The SS container I got at Walmart, or some such store. Maybe even a thrift store, but they are quite common s:2
and not expensive at all s:2s:2

It is about 5" in diameter and 8"tall, roughly measured with a tape measure. B)

The canister is not mounted permanently. While grinding I need to hold it against the port, with a finger over the lid to keep that on tight s:8s:8

The good part is there is no mess, and I can just dump it into a bag when it is finishedB)
The spring just helps keep it on when not in use. c:1

I've got to put wings on an idea I've had about discharging the static charge generated by grinding. I'll whip up a small Tesla coil or TV flyback transformer for a high frequency, well insulated high emf electrostatic field.

About like erasing magnetic media- tape, disc, etc- the high frequency alternating electromagnetic <Erase> field is used to rearrange the magnetic domains in random order.

12vdc at low power ought to to power the power oscillator circuit.

So simple- all I gotta do is try it out!
Cheers -RayO

i LIKE that idea there.
I have a doser on mine but I dont want to sit there and clunk out half ounce lumps of grounds for 10 minutes to fill a pound bag, which the thing will make in about 20 seconds.

Ill have to play now and see what I can rig up to mine.

"...a 42" Tesla Coil would look great in the midle of my wife's new kitchen. She might not mind it."

Oy, Brett. I haven't the slightest idea what you're referring to.

You don't know me- but one of my Hi school chums and I took the better part of a week after school to wind the secondary on a small carpet tube. Might have been about the size you mention. I disremember- I set up a big electrolytic cap as the mandrel at one end while one of us cranked a breast drill to turn the tube and the other fed the 40-gauge wire.

Scott (Perkins) and I were sitting quite a distance apart when we got the coil finished. Two 833A triodes in a Hartley oscillator. Too much- no sparks, just violet streamers would reach out for people as they walked by.

A transistor power oscillator with a flyback transformer would be less spectacular, but adequate. It's just a fire hydrant that also grinds coffee. I probably ought to resist setting the grounds on fire in the chute.
Cheers -RayO
