I thought that I'd post a couple of the mods that did on my Mazzer (before I sold it).

In standard form, the doser vanes of the Mini do not sweep the doser as efficiently as I wanted them to. To reduce the amount of cleaning required, the amount of coffee wasted and especially the amount stale coffee in the doser the electrical tape mod or the sweep mod is an easy to do and cheap improvement.

Just double fold an appropriate length of electrical tape and attach one strip to each of the vanes on the "star" section of the doser mechanism as per the picture. Just make sure that no adhesive surfaces are exposed!

Here you see the difference between the sweep efficiency pre and post modification...

I removed the finger guard of the Mazzer because it prevents easy cleaning of the chute area. However, it somewhat escalated the buildup of ground coffee on top of the dosing mechanism as pictured.

...to eliminate this problem, I found a suitably sized plastic cup, chopped it to the appropriate height (you'll want to have the top of the cup above the level of the exit chute) and carved in nocthes to match the dosing vanes - enabling it to fit snugly on top of the dosing mechanism...

...and the "inverted cup mod". With these two mods the Mazzer is significantly cleaner/more efficient than it was in stock form...

...oh, and the shorter hopper does make the Mini more convenient when placing it under the kitchen cabinets. The pic shows the difference - enough for allowing beans to be poured into the hopper with the grinder in situ vs having to pull it out. Looks better with the shorter hopper, too (imo).

Thanks. I saw that you just (finally) received your Mini, and thought I'd post these. Looking at the mods you've done to your other equipment, these probably aren't to the same standard so I look forward to seeing your mods...

Br,
Teme

Thanks for the Mazzer modding ideas. Easy to do for anyone & very clever. I was half considering attaching brushes to the wipers, but this should to the trick as well.

Simon, congrats with the Mini - it's a step up from the Rocky & you'll like it a lot.

Cheers,

HV

I just couldn't take all those grounds left at the bottom of the doser, so I was up at 12:30 last night doing the old favourite insulating tape job on the vanes. Much better now. I also removed the stainless plate that limits the dose per vane, as it just makes it more ricky to clean out, and I only ever grind for 1 shot at a time, so the doser is just used to deliver all that is in it to the portafilter.

How do you get the finger guard off? It really is a pain in the arse!

I totally choked the Silvia using a different blend to last night, simple tweak to (fractionally too fine) 30s shot. I do seem to be getting slightly longer shots before blonding with the Mazzer, but it could just be my imagination after splashing the cash Laughing

Good idea removing steel plate from the dosing mechanism!

With regards to the finger guard, in the newer Mazzer's it comes off easily just by undoing the two screws holding it place. However, on older Mini's I understand that the guard is also wedged in and is a lot tougher to remove. This is a quote of Mark Prince's review on CoffeeGeek:

"Basically you have to pull it straight up, with a lot of force and leverage. I would guess it requires maybe 75 lbs of upward pressure. I've been told by Chris Coffee to not worry about doing this in that it won't break anything, but still, you want to secure the machine (hold it down or have someone else hold it down), remove the hopper first (so you don't accidentally hit it), and get a firm direct grip on the guard as you attempt to lift it up. Be prepared for the instant where it releases, and your hands shoot up..."

There was also this advice from Dan Kehn.

I hope this helps...

I also found that blonding started slightly later with my Mazzer compared to the Rocky.

Br,
Teme

Thanks Teme!
Especially the Idea with the tape does wonders on my Gaggia MDF grinder. Easy, small end efficient!

McGyver would be so proud... although instead of tape, he might have used the silver paper from a stick of chewing gum Wink


----EDIT----
Teme, perhaps you could slap this into an article for the How-to?

In my case the hopper fell during sanding the new rim. A large crack was the result. I already bought a new one when I found that cutting the hopper down to the "cross" inside the hopper and fitting a doserlid also does the trick. So if you are a bit sloppy like me there is at least a second chance.

Regards, André

I must say I like the hoppers on the Mazzer. Although I'd like them even better if they were more like the hoppers on the Jolly (the cone shapes) in miniature.
