How and Why (?!) to Shim your Timemore Grinder - C3, Nano, & More
HTML-код
- Опубликовано: 5 окт 2022
- Well this was a surprise. Max pointed out that the burrs on my Timemore Chestnut Nano Grinder were still slightly abutting when grinding for espresso. This caused uneven grinding, and premature wear on the burrs. In this video, we shim up the internal stationary burr, in order to get it spinning concentrically around its axis, like it's supposed to. We go from needing to open to 12 clicks for clearance, down to 8. Just enough for espresso.
Thank you to CC Piano for posting the solution to this problem!

Thanks for watching, comments welcome!
"Max Mustermann" is the German equivalent of "John Doe" in english. "the person on sample pictures of official documents so as to not show real data"
To anyone whose C3/C3esp is only slightly out of spec (like, the burrs make contact at 7 or 8), I managed to restore mine to acceptable concentricity by tightening it as much as it could go (at this point around 1), then heating the section with the burr (no handle or grounds collector) in boiling water.
After heating for a few minutes, I found (with the help of tongs and a tea towel!) that I could tighten it further to 0. At this point I let it sit in the boiling water a few minutes more. Then I took it out, and left it to cool still at 0. Having cooled, I found it could now rotate freely within spec (6 and above).
For those with only slightly eccentric grinders, this might save you all the messing about with unscrewing the fixed burr, which I found to be a real pain with mine (and trying to make this easier is how I stumbled upon readjusting it with heat). It does leave the fixed burr unshimmed of course, so a sharp impact (like dropping the grinder, as I discovered) would push it out of concentricity again.
Another trick is to tighten down the center of the burr into the outer burr but with the locknut loose. this alines the burr assembly. you then tighten down the locknut. It then spins freely at four clicks or less. thanks!
Thanks Stephen, I will have to give that a shot!
thank you, I had to do it that way cause the casing of my C2 burrs is made of plastic and the gap was too tight. works like a charm now
Hi, could you elaborate on what you mean by tightening down the center of the burr into the outer burr?
Do you mean unscrew the locknut, then get to 0 click?
@@musicianoffailure-3804 Loosen the retaining ring for the outer burr, tighten the cone burr to '0', then tighten the outer burr retaining ring. This works because the conical (cross-section) shape will self-center the outer burr to the conical burr piece and become concentric.
@@BigBenAdvThank you, this worked for me! Spins freely around 6 clicks now. Only watch-out: Make sure the outer burr is loose (and not jammed like in my case) for the aligning through tightening the cone burr to actually work.
Wow this really worked . Mine was way out of center. I can go to 6 now no problem. It took me 10 minutes to do 17 grams at 6 but it was a test . 9 now seems a perfect basic espresso for me compared to a commercial grind.
Thank you for sharing the knowledge
Thank you! You just saved my grinder and coffee. I didn't know about this. I just assumed it was missaligned and I needed to pay more and upgrade. Now I have an easy fix c:
That’s awesome, happy to hear it! 👍🏻
great vid, thanks mate. I have this setup, so will look into the mod
Very nice Craig, thanks for watching! I hope that’s helpful.
Superb trick
Thanks for this!
Thanks, todos los días se aprende algo nuevo.
My new C3S after just a few cups spins clear at around 4 clicks, where Timemore recommends 6 as the minimum setting. If I spin just the outer burr, it looks perfectly centered!
That's great! I think they have since fixed this issue.
Hi Tom. Thanks for all the great videos. I have a question. My timemore c3 pro esp is somehow misaligned and when I turn the dial to maximum it stops at 1 instead of going all the way to zero. This happened after I disassembled it and put it back together. Do you know how to calibrate the dial so that when it cannot turn anymore it reaches the '0' indicator on the bottom.
Very useful
Thanks, I used 2 small pieces office tape.
To be honest I put some Teflon tape around it just like you would in plumbing it worked perfectly and it was easy to apply you should try it guys.
Ok, thanks for sharing the tip!
hey Tom, thanks for the video and for the tip! I am wondering, did you change the settings on your DeLonghi machine to be able to get a shot is about 30 sec with the 1:2 proportion or you are using a standard one? I couldn't see which button you pressed and whether you hold it or not.
At the moment, to pull a shot I have to press the button (for single espresso mode) and hold it until I get the right coffee-to-water proportion. Normally I can get 30-32 ml of espresso from 15 grams of coffee in around 24 sec, I am using Timemore Slim Plus with the burr set at 8 (doesn't go finer).
Hi Alex! With the Dedica, I just set the 2 cup button to be way too much, but stop it early. I like to either measure it with a scale, or eyeball it. Thanks for the feedback on the Slim!
@@TomsCoffeeCorner thank you for the answer 🙂
Hello! Nice video by the way! Is your c3 a bit loose after srewing? I mean, the bottom part where you adjust clicks. the "clicker" itself tends to rotate a bit (left and right) (without clicking ofc)
No, it's not loose. You just have to make sure to hold the spindle via the handle when adjusting the grind size.
Yes, thanks! But I mean, this big "screw" where you place two "wheels" has a small loose , about 0,5mm or less, and it allows to spin the "wheels" about few milemeters left or right (because of the loose on the screw), i bet its normal
(Sry for bad english hah)
Have the same phenomena with my C3. A big question mark for me,whether this is normal or something wrong.
One year late, but I've just encountered this video. My Chestnut C2 (though with metal nut) is spinning on first click and stops touching on 3rd. It's 3+ years old, seem I'm lucky enough to have it properly working.
Hey Tom! Thanks for this vid!
I picked up a Timemore C3 Espresso version with the 30 click dial wheel - so perhaps don't need to shim this device. This vid was helpful to see you grinding to an espresso blend using a manual grinder and using a standard basket. I've been using my grinder with the dual wall basket with my Bambino ... but now might have the confidence to go with the standard basket as it seems like you CAN grind fine enough. Not sure how fine to grind though use the C3 Espresso so if you have tips that would be appreciated - e.g. how many clicks back from 0 would I start with to dial in.
I haven't used the C3, but on the Nano it was 6-8 clicks. Cheers!
I don't know how you can have such a beautiful extraction with this grinder. I had a c2 that i modified with titanium burrs. there were always minor problems with the exractions. After testing with different roasts i saw that there were uneven cuts. After a while i sold it and now i wonder if i made a mistake.
It might very well have been because it needed to be shimmed. I was not getting very nice looking extractions before that, either.
😂 Love the shoutout to Max Mustermann! Greetings as well to his mother Erika! But on topic: thanks for this hack!
You betcha Tim, thanks for the feedback!
Just for everyone who is not familiar with the name Max Mustermann:
It's the german male quivalent of John Doe. Just an exemplary name.
I just bought c3s version. The seller said its upgraded version of c3. I don't know if I'm just lucky or timemore really fixed the issue with outer burr alignment. I do test my grinder and i only hear burr grind sound only at first 3 click. The 4th is all clear, the casing / handle can spin freely.
Then you should be good to go!
hey Tom i have one question, i just bought a timemore chestnut c2 and i dont have an espresso machine, i use a moka pot, should i shim the grinder if im not gonna grind as fine as espresso? for example, if burrs touch at 12 clicks and the finest i decide to grind is 13 clicks, should i still shim it?
I would recommend still shimming it if you can. Once I did that, my grind became more consistent, and I also was able to grind faster.
@@TomsCoffeeCorner thank you so much for the recommendation, ill try to shim it then, have a great day✨
What could it be with C3S Max, after i tighten and loosen to 7 clicks, i go to grind first beans, then i tighten back to finest but it goes 10 clicks? Somehow it loosens turning grinding
Tom do you think this grinder gives much better quality grind than La Specialista build in one does?
Hi Ivan, I don't think so. There is too little adjustment. But the Jx-Pro would give a marked improvement.
@@TomsCoffeeCorner perfect, thanks for suggestion. Just checked on Amazon, it has 5 stars. Def looking of getting one, to change the quality of shots.
I've noticed another important effect to keep in mind when using this grinder. it is made of thin aluminum (and not thick steel) and aluminum conducts heat very fast, so the heat due to the friction while grinding will fastly reach all the inner and outer burrs (you can feel some heat on your hand, when grinding). the heat do expand the metal inside, lessening the gap between the burrs and making them somehow collide (if, prior to grinding, your setting was that they were just spinning freely, to the lowest click possible). my advice is to make your experiments, because the poor thermal management of this grinder can affect (and deteriorate) your burrs. I ended up using this grinder only for moka pot (where the grinder is coarser than espresso), so to avoid any problem.
Hello Federico, thank you for that feedback. I’m afraid all grinders that I have seen are made out of aluminum. Steel would make them very heavy. In both metals conduct a lot of heat. Have you found a better hand grinder for similar price for espresso?
@@TomsCoffeeCorner I have also the 1Zpresso JE and it doesn't have this thermal issue. it has its own (different) flaws, but overall I think it's a better grinder if you're grinding very fine like the espresso.
😮 cool
Got my C2 Max couple days ago, tried 27 clicks (from zero start) for French press and the nut seemed substantially loose, while the grind was only marginally acceptable with mostly larger consistent grinds as well as some unwanted powdery slurry that ended up as muck in the bottom of my coffee cup; left me wondering what I did wrong.
I haven't tried the C2 Max, but you just have to experiment with the setting. If that was too coarse, then tighten the grind a bit. Cheers!
can i use the ims basket verybarista you recommended with the c3 timemore grinder ?
Heck yes, you can!
I cant seem to find an answer on this but does this trick work for the timemore c3 pro max....it doesnt seem to have the same space on the sides as the one in the video
Hi! The C3 Pro Max may not have the issue with the axle wobble. If not, then no need to shim.
Nice hack, also i think it would be easier to use the metal from a can of coke or beer, easier to cut and bend to your liking.
Perhaps, but I would be really careful with that, because those pieces would be super sharp.
My time more stops rubbing at 4 clicks. This grinder has been dropped a dozen times and has several dents. Amazing it's still calibrated.
Does this grinder have enough clicks for espresso? Or did you modify it somehow? I make espresso on one grind - I get 70 grams of coffee in 25 seconds, I do one less click - I get 10 grams of coffee in 25 seconds or something like that. :(
The resolution in this is not ideal, no. I would highly recommend the Kingrinder K4.
I've noticed this issue about my Nano shortly after I got it (burrs touching at 12 clicks as well). I've done quite a research and found a few posts on Reddit that were describing the same method that you've used. After trying it, the burrs started touching at 10 clicks - still too coarse for any attempt to make an espresso though. I've retried it now, 10 clicks it is for me. It's not that much of a deal as I use it for my office V60 anyway, but if someone wanted to have one main grinder for all types of coffee, I'd probably suggest going for something else.
I would suggest the Kingrinder K4. At the same price, it is a MUCH better grinder.
Twice the price in Amazon. Sticking with c3
Hello Tom, What kind of funnel do you use?
That's an Edesia funnel: amzn.to/3ypBLlx
HELLO TOM, TIMEMORE GRINDER, DO YOU RECOMMEND THE TIMEMORE Chestnut C3 ESP PRO? AM I INTERESTED IN ESPRESSO COFFEE, OR DO YOU RECOMMEND ANOTHER GRINDER?
I have not tried that one yet, but I have heard that it’s a good one. My favorite is the K4 or K6 from Kringeinder. Cheers!
Hello, I bought an ims 18g nano and I still haven't been able to make the shot join in a single shot of coffee with the original gaggia basket, the shot of coffee always joined. What do you recommend to be able to achieve it, I always use 18g of coffee.
Hi Victor, which grinder are you using, and what kind of beans?
Tom I'm using baratza encore and the coffee is medium light if I put the basket that came with the bottomless portafilter it comes out perfect and I put it finer and it takes 45 seconds to make 36g of coffee
Ok so you say it comes out perfect, but just doesn't look that good? Maybe try WDT method. 👍
@@TomsCoffeeCorner Tom s also use the WDT method always
I use a c2 with that new knob from c3 esp and it takes about 10 minutes to grind 18gr on click 25. I hate how long time it take to. Is it normal?
It should take like 40-50 seconds.
Any video for Timemore C3 Max? It's different from the inside. I can put out the last part.
I think they fixed this issue on the C3 max. Cheers!
My C3 pro doesn't seem to have issues if i have it spinning, but I tried both level 7 and 8 but still it's a bit too much liquid and not much cream (14 in, 30 out). Any help ? Using pellini n82 vivace
Well, how long does the shot take for that 2:1 ratio? You could try 1 click finer...just make sure the burrs aren't abutting.
Same, 7 clicks and too much liquid, very disappointes. I got cheap delonghi which is grinds fine for espresso.
@@Edgardo.o found best settings in: level 8 with double filter 18gr in. Or level 7 single filter 14gr in. Or level 6 single filter 11gr in.
@@pizzatimechannel did you try 5-6 clicks just watched amother videos people using under 7, just dont want to damage the burrs :/
@@Edgardo.o cannot go lower than 6 from my tests, or it will "explode" damaging the sealing ring. I had already to replace it twice
Does this happen with all versions of timemore or only with the nano?
I think it happened with the C2 also, but they may have cleared that issue up by now.
How many clicks do you need for a Timemore C3 for a geyser coffee maker?
Not sure, I would try 10 at first.
Hi, I bought a Conqueco grinder for 117 euro with steel blades, I can't find a tutorial for settings to grind coffee for a Delongi dedicated to could you help me?thank-you
Hi there! I have never tried that grinder, so I don't know the resolution. But check this video for reference: ruclips.net/video/-Aj9i8QGUKo/видео.html
Don't you find the squeezing noise from Timemore annoying when opening the bottom container?
Oh yes, it's ear wrenching.
Can I get the same result with timemore chestnut c2?
Yes sir.
Just got my C3 and it spun clean at six clicks, maybe they got more precise at making them.
Sounds good, thanks for sharing!
my C2 doesn't seem to have this issue with the outer bur. I think they fixed it with the updated version
This video must be earlier than now )before I bought another one grinder ,now I have chestnut and kingrinder)
So which one do you prefer?
@@TomsCoffeeCorner Thanks for answer Tom,kingrinder k4 is much better than C2 ,burrs synch best ,but I have standard portfilter on my EC685 and today I tuned my C2,I think keep it for alternate methods.Thanks for you tips,burrs is sync better a Little bit after this. I would be glad if you recommended a dosage for a standard portofilter, because I can't repeat the result. I don't know what the reason might be.Now I use 14g and 25 sec,but sometimes there is an acid taste ,not a delicious shot,and you do it so easy and perfect ,I’ll be glad for your help.
@@akselerant Hi there! Well, the dosage depends on the roast. Medium roasted beans are denser than dark roast, so you can fit more in the basket. For example, on the Dedica, I try for 14 grams of darker roast espresso. But if I am using light or medium, I can fit even 17-18 grams, due to the higher density.
You will just need to experiment with your dosing, as well as trying the steam temp hack: ruclips.net/user/shorts8GO1b94CgN4?feature=share
@@TomsCoffeeCorner Oh Tom ,thank you very much ,I tried the hack temperature too,now I will know that dosage depend on roast.I will try with fresh roast coffee and give the feedback to you.Sorry for my not so good English)I hope you saved my espresso )😊And another one question, Do I understand correctly that for different grains it is necessary to use the maximum dosage in the holder?
Is this also true for the chestnut x?
Not sure about that...
Hey tom, timemore c3 its good grinder?
It is a big time seller, so I am assuming it's good. But I never tried it myself.
@@TomsCoffeeCorner you use that on video Tom, So you dont try? 😃
Good afternoon, Tom, if you can help me with the problem I have, friend, I'll explain. I bought a gaggia classic pro 30th anniversary a month ago and a baratza encore I tried to grind finer and the mill got clogged, there will be a number and when the extractions come out with 18g of coffee takes more than 40 seconds for 36 g of coffee and the coffees come out super bitter I hope you can give me light friend I have asked a lot and nobody has helped me, I am using google translate because I speak Spanish only if you have one good afternoon .
Hola Victor, que pasa?! The Encore is a decent grinder, although not very ergonomic. If it is getting clogged, maybe you are grinding too fine. Also, if a 2:1 ratio is taking more than 40 seconds, you are likely grinding too fine. Try 2-3 notches coarser. Maybe watch this video: ruclips.net/video/RLdQXlhUX8M/видео.html
Cheers, Tom
Ok tom s I'm going to try right now I'm going 2 thicker clips to try, but first of all thank you very much for responding, I also received an 18g ims barista nano basket today to see how it goes.

Toms where can I buy a used grinder that is good better than the one I have encore or should I not buy another one, and keep trying
@@victorm.claudio7801 why did you copy my words of my comment
I think only the nano have this problem cos my c3 didnt move when i spin it
Hi Gary, thanks for that feedback. Still a good thing to keep an eye on. Cheers!
My c3 has a lot of give to it, it's really loose like his nano, but my burrs don't touch until 4 clicks. I feel like the give is definitely an issue, but for my purposes it is still usable.
You better use some thread lock paste to fix this issue.
I'm not so sure I'd want to use that though in a food product...or do they make food safe lock paste?
@@TomsCoffeeCorner you put it on the threads only, It doesn't touch the coffee, or you can use teflon tape. Just need to fill the threads a little bit fermer.
The problem with the Chestnut C3 is that it doesn't have fine grind settings. C3's 80-83 microns per click is too big compared to 1Zpresso's 8.5 micron per click. So there is no way we can perfectly tune the C3 grinder for espresso extraction. There is only one setting for espresso extraction. If we go 1 click above then the extraction is going to get delayed and if we go 1 click below then espresso will get extracted more quickly. Not perfect for espresso lovers. Go for the 1Zpresso.
I actually prefer the Kingrinder K4, which performs similarly, but is in my opinion nicer to use.
@@TomsCoffeeCorner I have to try both 1Zpresso as well as Kingrinder K4. Thanks for mentioning the Kingrinder name because I haven't heard about this. K4 & K6 grinder has 16 microns per click and the rest are 18 microns per click. Another precision grinder. 👍👍
how to replace the lid timemore c3
What do you mean by lid?
@@TomsCoffeeCorner thank u Tom for your reply . I mean the plastic lid cover on the crank
@@lucasyu9224 I don't have this grinder anymore, but I think that it was metal. Anyway, to take that apart, I think you'd have to pull a pin.
@@TomsCoffeeCorner Tnx Tom
I have a C3 and it has zero gaps that you can put a shim to. So its not good for C3
I think that Timemore has started to correct this shimming issue in the C3.
not working on C3
Rats! Maybe yours was already tuned well?
Does this apply to C3 Espresso?
I've heard the C3 is better, not requiring shimming.
