Adjusting grind on DF64 (and perhaps DF83)

Maybe cutting some kitchen grip mat and using that when changing grind size could help adjusting?

Having spoken with my retailer and distributor of the DF64 in Australia, the suggestion is not to over lubricate the threads but
to make sure the threads are clean, try a new collar (which will be provided by post) or get Auspresso to take a look at how I've replaced the hopper and collar. Super helpful!
It is good to have this local support for my DF64 :-)
It's a grinder that has really opened my eyes to the possibilities of coffee!

I did not use this grinder. But sometimes tighter adjustment collar is pretty normal for new grinders. You can carefully apply a small amount of food-grade lubricant around the thread. However, if it does not work, contact the manufacturer and explain the issue to see if they can assist you further.

I tend to shy away from all greasy/oily lubricants for use on grinder threads or other metal bearing surfaces. Better to use a dry PTFE based lubricant or even Graphite Powder (used by locksmiths). Both are economical to use with emphasis being on the "Less is more." principal.

Great suggestion, which I'll try too. Makes me think that it could be coffee fines actually sticking to areas that had lubricant on them around the threads (not actually on the threads). So I might try cleaning the thread and bits really well and then carefully applying lube on just the threads and not spreading it all over the place.

Yes, I've lubed the main thread on the collar but it was a while ago now. I've got the v2 and I've also done the alignment trick twice now (not shimming under the screws though - just rotating the carrier to find the best alignment, which was pretty good, as it evenly removed the marker ink).

Also found this video here which I found quite helpful, https://youtu.be/MWgMyYHuBQ0

I just tried turning it while pushing down on the hopper and it moves easily, so I think I might need to clean the contact between the hopper and the collar. Time to get some food grade lubricant!

I bought it from Auspresso in Parramatta. They are very close so I might have a chat with them too.

Might be your collar my DF64 is relatively new and I have not had this problem. I have only ever struggled to move the collar when I have screwed it on too tightly after cleaning the burrs.

Hi Paul,Originally posted by paperythinideas View PostHi all, really enjoying the latest DF64 I purchased a month ago.
I have been adjust the collar back and forth from 24 to 65 and back as I make espresso and V60 through the day. The taste of the coffee is incredible in both cases (compared to me built in Breville conical burrs).
However it is always very difficult to adjust down from 65 to 24. I turn the grinder on to make it a little easier, but my hands tend to slip on the collar. It makes me not want to make filter coffee.
Is this something others are finding? Is it because the springs are very tight when the grinder is new? Will it get easier, or should I try to add more lubrication to the collar?
Thanks in advance!
Paul
Where did you buy the grinder from? Maybe best reach out to them and see if they can get you a new collar.

Chirping might not necessarily be that the burrs are actually touching. In some cases you may have a fragment of a coffee bean that did not grind and is lodge in there somewhere. The sound should disappear as it eventually gets ground when going finer.

Exercise caution if using Molykote..... they do make food grade lubricants but many of their other lubricants warn that they must not be used if there is any possibility of contact with any food item.
There are plenty of food safe greases available (and they are good for portafilter seals as well as assorted O rings).
Vaseline grease is food safe for example!
