    Have found that applying a slight dusting of Graphite Powder to the thread beforehand can help prevent this. Or, if you live near a cycle accessories retailer, a high quality dry chain lubricant (with PTFE preferably) is even better...

    Similar thread to this a while back - https://coffeesnobs.com.au/grinders/...h-problem.html

    I've used a H1 Food Grade grease sparingly (wiping off excess) on my K3 for the last few years. The actual brand is
    BioGrease Marlin-9 Food grade grease H1 (BGI-93HT).

    Re-assembling without some form of lubricant will cause galling and possible thread damage if you're heavy handed.

    Lucky I have some chain lube, used a bit on the threads, worked good. Now i’ve just wasted 1/2 kg of quality coffee trying to dial it back in ����*♂️, lesson learnt!!! Thanks for the advice.
