Subject: Commercial Espresso Grinding Beast tamed for home use - Sold
 

I am selling my Faema MPN grinder.  I really like it but I need to consolodate from two down to one grinder, so I plan on getting a Baratza Vario.

Photos: http://s436.photobucket.com/albums/qq89/Monkey_K/FaemaMPN/

This is a commercial espresso grinder that I have rehabilitated and modified.  
The modifications that I have done make it similar to a Faema MPN S without a hopper. Base features of this grinder:
-Heavy Duty 300 watt motor (120v)
-54mm flat burrs
-very fine stepped adjustment.  It has 48 steps of adjustment per revolution (and a revolution is a pretty small amount at that --measuring the threads, there is less than 1mm/revolution)
-doser, adjustable from 5-9grams


The Faema MPN is built to provide fine adjustments, consistent results, and high output in the demanding environment of a busy coffee shop. New the Faema MPN would be a $1000 grinder.  This one is far from new, but easily continues to fulfill it's purpose.



What has been done:
-Thorough cleaning

-Put in new burrs.  The new burrs have seen less than 20 lbs of coffee, so they should just be hitting their stride.

-Replaced what remained of the hopper when I got it with a small collar extension (well really 1/2 of a grocery store bought cheese shaker).  This provides a couple of benefits:
1) it provides a decent means to percussively clear out some of the remaining grounds by slapping the top of the collar extension with a cupped hand.
2) The height of the grinder is reduced from 23 to 16 inches
With the extension in place there is room for about two double shots worth of beans.

-Bypassed the hopper interlock switch. As a commercial grinder, this grinder is set up by default to require a hopper full of beans to run. Bypassing the switch allows the grinder to run without a hopper full of beans

-Removed the automatic shutoff lever and switch.  Realistically this was just another thing that became hard to clean.

-Removed the Doser cover bolts.  This makes it possible to clean out both the doser and the ginder chamber exit.  

-Removed the built in tamper.  It mostly just got in the way.


There is onle problem with the grinder: the a couple of screw mounts on the adjustment collar plastic are cracked from screwing it to the brass part too tightly.  The cracks are not visible  and the plastic has been superglued together, but it does make the adjustment collar look as if it is not straight even though it is.


I have little exprience packaging something like this, so I really prefer a local sale.

Mike:

I'm interested, but obviously... I'm not local.

Can you please tell me the full dimensions of the grinder (Ht x Width x Depth) I need to know if it will fit where I keep my current grinder.

So... as far as I can tell from your description, it's built like a tank, functions without any flaws, and has a few minor cosmetic, not functional issues.

What about reliability, maintenance required?  How hard is it to keep it clean, so that you don't end up with stale grinds in the mix with the mods you've made?  How stable are the grind settings?  Does it have any tendency to float around?

Thanks for the info,

Rick

PS...  what do you think shipping would be to South , Florida?

(feel free to email me @ rsingerATcomcastDOTnet)

Rick, I think that the answers to your questions are probably useful for a range of people:

Height: 16 inches
Width: 8 inches (but to use the doser arm, you would need space for your hand)
Depth: 12 inches

The grinder is a Faema MPN.  It is indeed built like a tank.  


As for subjective attributes, please consider that I have only been making espresso for half a year.  I started using my Solis Maestro Plus (also for sale) with my Solis SL90, and thought that I was doing OK.  I bought the MPN to see if there was anything to all of the claims of the Solis MPs inadequecy for espresso (verified).  I can usually  do better than Caribou, but it is not infrequent that my cap turns into a mocha ;)

I think that the MPN grinds consistently.  Based on the construction alone, float is unlikely: the adjustment collar locks into the steps quite firmly.   That said, I do not know how I would verify that it does or does not float around.  

I feel that reliability should be high and I have not been given any indication to the contrary.

Cleanout appears to be a weakness of the MPN --by design even.  I could see it and several reviews suggest the same.  Most of what I have done has tried to address that.  By allowing better access to the doser, the doser and grind chamber exit chute are relatively easy to clean.  Clapping the extended collar also helps to clear out the grind chamber.

LOL

I guess that I forgot one mod.  I am not above humiliating the beast as part of my domestication program.

This is true. I removed the same two bolts you did, and I found that with practice and care, I was getting <0.2g grounds retained according to my measurements. The doser, with a little assistance from a brush, sweeps very clean for me. Good luck with your sale. It sounds like someone's going to get a good grinder at a great price :-).

I think that I must have seen the post.  I recall seeing something to the effect of using an easter egg and it seemed like a good idea to keep the ground coffee off of the center of the doser.  Ideally I would switch it out for something taller and steeper, but an easter egg is pleasingly comic as well.

Thanks for the idea.

Cheers!  I was enamoured by the frivolity of the egg, too.  I'm happy to pass on any old silly thing that I come up with, and happier still if it he'ps a brudda out!

I know I'm not really local, but I need something better than my $40 black and decker.  Any interest in shipping to Ontario, Canada?
