T64 Grinder From Bella Barista

Adrianmsmith The 2mm o ring did its job

was that to stop coffee getting under the burrs?

Adrianmsmith

That seems to be its only purpose as with the original ring for the mazzer burrs.

I’m having grind setting problems in dosing my espresso grounds. I was using it on setting 65 for pour over. I switched it to 15 to do espresso and the grounds are all messed up, chunkier, coarser and uneven. I think I got a bean or two stuck in the burrs because I can hear rattling. I’ve tried rotating it in a couple different ways but now i’m lost at sea. What may I be doing wrong here?

gregE

Quick update. I sat myself down and said you can do this. Be smarter. You can see in my photo there is a bit of silver thread showing where the grind settings are. I think i needed to tighten it more by rotating it back in more. The turning mechanism is both used for the grind settings and to screw or unscrew that part on or off. I think i got it to grind more consistently now.

Unscrew it completely and lift off, throughly clean out the grind chamber then recalibrate.

Interesting observation on this T64. The grinder leaves about 0.2 to 0.3 grams in the chamber as that last amount needs some extra gravity to take it through the chamber a couple mins after i turn off the grinder. As such, i either grind 18.4g and let that amount sit in the grinder (and purge before next use or use in the next use) or i wait a minute or two, turn the grinder back on and get that last 0.2g or so out. Or third option, don’t worry about it. Any of you have this experience or notice this? Just flagging my experience.

gregE I’ve removed the protector in the chamber and covered the holes with electrical tape which seems to reduce grounds from that side but a couple of knocks and puffs generally gets it all out.

gregE that amount sounds about right, it’s pretty standard for single dose grinders in my experience . As long as it isn’t significantly impacting shot consistency you’ll be good! I weigh in and don’t bother to weigh what I get out, I just rev the rpm dial at the end to get any final grinds out.

Get a bellow to puff it out after grinding

gregE

Tal I do have the bellows. That is even after this. I use the bellows near the end of the grinding.

gregE

dang2484 Thanks, interesting I will take a look at that

gregE

FadedFrontiers Checks out! thanks for the confirmation

I am firmly in the “don’t worry about it” camp :)

Think we chase perfection in something that is a chaotic system, chill with the still, listen to the dolphins

hi, i have similiar grinder but not from bella barista it come with lcd rpm display and step adjustment , but the grinder only will run at adjust rpm for 15 sec and then go full speed, did anyone know how to make it run at designated rpm full time or make it to 25 or 30 sec ?

some beans with 18gram dose cant be done in 15 sec at 1200 or lower rpm

kiva - looks like it’s a feature… a very annoying one….

And by the sounds of it Dave fed that back to the manufacturer and they removed from the one sold by BellaBarista at least, as I haven’t heard anyone complaining about that.

MediumRoastSteam The BB one ran for 60 seconds then cut out if my memory is correct

Yup a really anoying one

Maybe will open up the grinder n take a look the pcb

Hope to find how to change or disable the timer

The Bella Barista version did cut out after about a minute…I have no idea why6 they changed it to 15 seconds? I think this shows what happens when no one keeps a weather eye on things and manufacturers make “improvements” no one asked for.

Update on the DLC burrs, as I finally got round to fitting them. As was the case with the Mazzer burrs, the lower moving burr carrier was slightly too small for them to sit fully flat. I could have still installed them but it would be poorly aligned (or required filing) which was not worth doing for me so I reverted back to the SSP HU straight away.

Getting the HU out and then back in made me appreciate how close the tolerances are compared to grinders like the DF series. After putting them back in I’m at the same lock and touching point, something that would have shifted drastically had I done the same with my old DF64 v1.

Not much retained grinds either, after cleaning out and putting 16g of beans in I got 15.6g out for my first shot. After a few more shots it should give closer to 16g out again.

FadedFrontiers The tolerances on the T64 are tight and quite accurate.
