Yeah that's an idea.. the slots on the plastic clip do fit really snugly into the carrier teeth though, but it's just the way it fits into the hole that I reckon is the issue.. Just sits too loosely in there, the hole being bigger than the insert..

I had a closer look at this / your photo (below) see area on left hand side the hole
And would like another photo from above please so I can see it better without the clip
It's possible that a removable/ replaceable collar is fitted in the top of the recess to stop the movement and it's gone missing

This is a photo of brass "shaft guide collar" that I found on the internet so you get the idea of what I am trying to convey

Ah wow, that is a very real possibility haha... yeah as far as I know it came like that, there is just the hole, adjustment button, and the spring that sits inside the hole. It would make sense that one would be there to guide the shaft and hold it still.. pics below.

 Ps. I really really appreciate all your help with all this KK, I'm at a loss with all this, and close to just getting a new grinder, but if I can salvage it that'd be great as I do love the grinder otherwise

I am a mechanical engineer so I look at things logically

You see on the last photo - there is a larger recess hole (top) for a few millimetres to that of the lower section hole where the spring is
If your lock pin is swimming in that larger top section but snug in the lower section - then we may have found your issue
You probably need a guide collar
Contact Paul to see if a new unit has a collar or similar guide insert that slips in from top all the way to the bottom to confirm

Thanks KK, yeah I even looked it up on the Quamar website and the schematic only shows the pin and the spring, so not sure if there are any newer models, and also the Bombora one they have all sorts of spare parts and they only sell those too, no guiding collar (they didn't have the Q50 on there, but had a few other Quamar and Fiorenzato grinders that had just the button and spring only).
I even rummaged through the old box for the Quamar and couldn't find any missing pieces hehe.. I wonder if there's anything similar I can buy at the hardware store, otherwise I'm just leaning towards a new grinder... :( and selling this one to the lucky person who wants it :D ;D.

That's the thing, if it's really only just my grinder doing and not many others, then it doesn't make sense, if it generally didn't come with a guiding collar everyone's grinder would be having the same issues.. anyways I shall ask and see.. Thanks mate

Will also try wrapping foil around the shaft, the paper i tried just screwed up ripped when I tried putting it back in the hole haha..

Based on all the supplied information of the fault
I am confident that we have found your issue

You have a couple of options
1) Add a thin metal tube sleeve over the plastic shaft - this will take up the slack & make it tight in the hole and will take the daily use operation
2) Add a collar on the top

3) ditch to and source a replacement. The amount of money you're saving by making coffee at home means that you've paid it off in a year!

You might actually be able to use a locking pin from another brand too. If it's better quality and the shaft is slightly thicker that'd be ideal. Even if it's slightly too big you can always drill the hole out to fit.
I love coffee. It's as simple as that.

Thanks KK, tried foil around the shaft but it kept ripping up, so tried some tape around the actual adjustment button, and that's actually really helped keep it more steady, as the button sits in with minimal movement. Upper burr carrier has only slight movement now when I use my hand as it's filled in any slack in the hole where the pin sits, and also can't see any 'snapback' when I turn the grinder on. Will give it a crack and see how i go!

But if this doesn't work, and if this movement wasn't the issue, and the steps show to be too large I don't what next as I can't explain it, unless my technique is THAT poor which I can't see it being honestly, I'm thinking try:

-teflon/hemp tape
-different filter basket
-up/sidegrade :s
3) ditch to and source a replacement. The amount of money you're saving by making coffee at home means that you've paid it off in a year!
Yeah am sort of leaning towards that at this stage.. Will trial out some other stuff first then will bite the proverbial bullet! I'm happy to pay a bit more for a grinder than the price of this one, $800ish should be doable..

Hehe love the dedication crossing over forums for pretty much the same thread, cheers mate XD.
Yeah I considered that, just not sure if the teeth in another locking pin would fit in collar for this grinder.. they're all different I guess, but will keep in mind for sure!

Pulled two shots today with the 'tape' mod, going only one notch finer from first to second shot.
After the first shot, I even removed the beans from the throat, removed the top burr carrier, swept, toothbrushed, AND vacuumed everything out, then after reassembly I purged about 14 grams or so on the new finer setting, to reeeeally make sure old grinds weren't the issue. Results:


-20g gr2.1 y38.3g 25s
-20g gr1.5 y21.4g 35s

:( quite drastic a difference still..

So it doesn't really seem that the stability of the upper burr carrier is the issue, the tape really held the adjustment button and thus upper burr carrier really well..

Will try a different filter basket tomorrow..

Okay, so I ended up spontaneously buying a secondhand Compak K3 Touch Advanced. Super excited about that, to be honest I'm at a point (not just with the grinder specifically, but in life in general) where I want to simplify how I do things, and not get so caught up in minor things. I know I have the patience and tenacity to have potentially sorted this all out, but honestly I was just done.

Want to be able to just move on and stop hesitating and dillydallying, so the timing was perfect, so I jumped on it.

I want to take this time to thank each and every one of you for your amazing support and help, especially KK. Honestly have learned so much more about coffee and grinders in general from this thread (and from constantly taking apart my grinder haha), so none of this thread or your answers have gone to waste. Know that I truly appreciate it very much.

Looking forward to a new chapter haha :), thanks all.

Well sometimes you need to bite the bullet and move on
You want to be making and drinking coffee ☕️ and not in daily repair

I would say that many of us have had similar issues at some point in time with equipment in general and sometimes it’s best to trade up

Now let’s return to drinking coffee ✅
