I found this old post and it got me fired up to do a burr swap on my mini. I didn't want to purchase the outrageously expensive mini-e burr carriers so I modified the existing carriers to take the SJ 64mm burrs. Photos can be viewed on HB here (multiple photos are easier to post on HB).

Found this thread while researching the Mazzer, and even though it is an old thread, was glad to see ethorson revive it. Ok, I just wanted to confirm my assumption that the burrs (64mm) are the same in both the Super Jolly and the Mini Electronic A&B. With that said, I know the burrs in the Mini-Doser are 58mm. What I gathered in the beginning of the thread that they wanted to put burrs from an SJ (64mm) into a Mini-Doser (58mm), and, assuming my interpretation is correct, that this can be done as a "bolt in" (no machining required) by changing the burr carrier and burrs from the Mini-Doser with a set of burrs and carrier from the SJ. And again I'm assuming that the grind difference issues between the Mini-Doser & Mini-E are resolved, giving the fact that they are basically the same grinder except for the burr size, and the obvious doser/doser-less thing. Ethorson, once again I get to see the engineer, great machine work. I've followed your projects on your BZ35, I also have one of these that still remains a work in progress. I miss the days when I had access to a lathe and "GOOD" drill-press. But I wanted to chime in to verify if this swap could be done as a "bolt-in" with, the parts, some hand tools, and a little know how. I currently decided to buy a new machine & grinder, but wanted to file this in under "good to know" information for future reference in case a deal comes along on a Mini-Doser to pair with the Bezzera.

I have not seen the SJ burr carriers so I can't comment on the fit in the mini. I did find that both mini burr carriers had to be modified to take SJ burrs. This does not agree with one post that claimed the upper burr carrier was the same. It is possible that Mazzer has changed the design over the years.

After using the conversion for a month I can say that I am delighted with the results. The mini motor does not seem to have any problem driving the SJ burrs in a home use setting. It grinds much faster and seems to be very stable. I was surprised to find that the adjustment ring calibration marker ended up in nearly the same position after the swap even though the SJ burrs are thicker. It could be that the difference is exactly one turn of the adjuster.

I see what you mean by the price of the parts, (about $300) may be worth to find a small machine shop to do the work. May have found a deal on a used Mini-Doser, going to check it out this weekend. Thanks for posting this, looking at the Mini-Doser & the Mini-Electronic I don't know why Mazzer didn't use 64mm burrs across the board.

Ethorson, want to thank you for posting the pics you did on you burr swap. I found a small machine shop that will do the work and found the burrs for $40, so I'm about $100 all in for the swap part. Haven't got to see the grinder or should I say grinders yet, but I'm told I should be able to make one from the two. It's a friend, of a friend, of a friend, kinda deal so I have my fingers crossed. Either way thanks for sharing the info, I'm surprised there aren't more owners of the 58mm mini's making the swap to the 64mm burrs. After all the I believe the motors in the Mini-Doser and the Mini-E are both the same at 250 watts.

Can someone please confirm whether or not both the upper and lower Super Jolly burr carriers are required to fit the SJ burrs onto a standard 58mm mini? While pricing the parts I saw that 1st line sells only one upper carrier and states that it applies to the SJ, MiniE & Mini while espressoparts sells both a Mini upper carrier and SJ carrier. Thanks

I believe they are different based on the part numbers and ethorson's photos. Clearly the screw pattern is larger for the 64mm burr set. Maybe the upper at 1st Line is double drilled for either burr set?
