I just bought a used Super Jolly that was used in a coffee shop. It looks to have been built in 2000 and had quite a bit of caked on coffee residue everywhere. After a few hours of disassembly and cleaning it looks pretty good. I am now attempting to get it dialed in and I was hoping to get some feedback on how it sounds.

When I see other videos the mazzer seems quieter so I thought I'd post mine here to see if anyone can tell me if this is what is normal or if perhaps I have an issue. Thanks in advance!

Sounds perfectly fine to me.

Yep. Sounds exactly like mine. I would definitely look into replacing the burrs though, if you haven't yet, as I'm sure they're well past their life.

Thanks for posting, really. I had the same question when I bought my first SJ last spring - and the question still nagged me every once in a while. No longer.

Thanks for the feedback. I just got some new burrs for Christmas so I will be replacing those. Also, I am thinking about refinishing my super jolly like jmelan did and I was wondering if I should be replacing the bearings while I had it all torn apart. Based upon the responses, it seems like I can skip the bearing replacement and move on to the other fun mods I have been reading about here.

If you watch closely, the burrs are not moving in a perfectly circular motion; they seem a bit off center. I've often wondered about my SJ that does the same thing, and now maybe won't be so concerned. My grinder came from a ski resort after it was shelved because the doser screws came loose and stopped working. I have feared it was damaged in some other way because of the movement of the burrs. After I cleaned it up and replaced the burrs, I really think it brings out a more rounded flavor than my Baratza Vario. I should just stop worrying and enjoy the coffee.

I expect it's just fine, and what we (think we) see is an illusion of wobble due to alternation of irregular light and dark patches on the spinning parts. If it keeps you up at night, you could open it up and measure the runout with a dial indicator, but with that much mass spinning at 1600 rpm you'd have a noticeable vibration problem (and more noise) if there was significant wobble.

I have noticed that it is possible to install burrs slightly off center on top and bottom burr carriers; it takes a little care and paying attention to detail to avoid screwing it up.

I hear a very slight rubbing. I've watched and re-watched at full quality, full screen just to feel like I'm sure: spinning comes to a full stop at the same point where the rubbing is happening. Don't feel like I see any wobble, though.
